Create Motion Group

When fixtures in a room are configured as a motion group, the occupancy detection is communicated to all fixtures when an occupant enters the room. The fixtures will react and adjust their light levels according to their configuration in their profile.

Motion groups are listed in a table under the Groups > Motion tab.

Motion_Grp_List.png

A group can be created when a floor is selected. Additionally, groups can be edited or deleted by clicking the Edit or Delete button.

Note: Since all fixtures and plugloads in a group must be bound to the same Gateway (GW), fixtures from other floors cannot be supported.

You can create, edit, or configure a motion group’s configuration. 

Creating a Motion Group

The steps to create a group are:

Step 1: Click Facilities in the left navigation panel and select a floor. Note that a group is created on the selected floor and cannot be moved to another floor.

Step 2: Click on Groups

Step 3: Click on sub-tab Motion.

Step 4: Click the Create button above the groups' table.

Create_Motion_Grp_List.png

Step 5: In the Create Group pop-up, specify the name for the motion group, select the type of fixtures (firmware version) in the group, and click Ok. This will result in an Edit Motion Group pop-up.

Create_MG.png

Step 6: To add fixtures to the motion group, click the Fixture tab.

Step 7: Select the required fixtures on the floor plan.

Step 8: Click the mceclip2.png left arrow button. The fixtures are added to the Fixtures table. To remove fixtures or sensors from the table, click the mceclip3.png control.

Note: All fixtures in a group must be the version specified when the group was created and bound to the same Gateway.  

Edit_Motion_Group.png

Step 9: Choose a role for the fixture.

  • Act only – the fixture “acts” on reports of motion received from other members of the group. Fixtures will do (act) whatever is configured in the profile to do when motion is sensed in the group.
  • Report only – the fixture only “reports” or informs all fixtures in the group that it has sensed action.
  • Both – the fixture acts and reports to the members of the group.

Step 10: Plugloads are Act only devices that act based on reports received from fixtures. Suppose you prefer to add Plugloads to the motion group, click the Plugload tab, choose a role for the Plugload, select the preferred plugloads, and add them using the mceclip2.png left arrow button.

Note that the Plugloads can belong to multiple motion groups, or multiple plugloads can be in the same motion group.

Step 11: Click Apply and close the Edit Motion Group dialog pop-up.

After creating a motion group, it will take two or three minutes for the fixtures to be updated. If a fixture is powered off or rebooting after an image upgrade, the fixtures cannot be updated until they are operating normally.

Editing or Deleting a Motion Group

From the Groups tab, select Motion, and click Edit the desired group. Make changes in the Edit Motion Group pop-up and click Apply to save edits.

Before you delete a group, you must remove all fixtures from the motion group. In the Edit Motion Group dialog pop-up, select sensors in the table, click the mceclip3.png control to remove sensors from the group, and then click Delete.

Create Switch Group

Up to four Enlighted Room Controllers (ERCs) or EnOcean physical switches can be associated with a virtual switch to control a group of fixtures' light level. Refer to the article Adding ERC or Adding EnOcean switch. 

Creating a Switch

Most configuration settings for a switch are dependent on the floor plan information, such as the Location, Device, Scene, ERC, EnOcean that can be associated and controlled by the switch. You can control all these in the Edit Switch Group dialog box. Refer to the article Switch Configuration Settings.

The steps to create a switch are:

  1. Click Facilities in the left navigation panel and select a floor. Note that a switch is created on the selected floor and cannot be moved to another floor.
  2. Click on Groups and sub-tab Switch to display the switch table.

The switches are listed in a table. 

Swtiches_Table.png

  1. Click Create. The Create Switch popup is displayed.

Create_Switchpopup.png

  1. Type the switch name in the Enter Switch Name field.
  2. By default, the system ships with the Template_20_40_60 scene template, which determines the light level setting from 20% to 40% and 60%. Select the scene template from the drop-down box. If your organization requires additional templates to meet the requirements specific to your conference rooms or building needs, see Creating a Scene Template.
  3. Click Ok. This will result in an Edit Switch Group. The Edit Switch Group window has several fields. Refer to the Switch Configuration Settings for a detailed explanation of all the fields related to the switch.  

Edit_Switch_Group_First_Display.png

In the Edit Switch Group dialog, click on the Location tab, and then right-click to select the Set Switch.
Position the switch icon on the floor. The virtual switch icon appears on the floor plan.

Edit_Switch_Location.png

The next step is to associate sensors to the virtual switch. A prerequisite condition for this is the sensors  in close proximity to the switch must be enabled to SCAN mode. Refer to the instructions in Set Bluetooth Mode to enable SCAN mode.

Click on the Device tab and select the sensors to be controlled by the switch. Click the left arrow Left_arrow.png 
button to add the selected fixtures to the Fixtures table. To remove fixtures or sensors from the table,
click the right_Arrow.png control. 

Suppose you prefer to add Plugloads to the switch group, click the Plugload tab, choose the plugloads to be controlled by the switch, and add them using the Left_arrow.png left arrow button.

Edit_Switch_Devices.png

Click on the Scene tab and create scenes. For each scene, adjust the Light Level for each fixture. If the fixture supports Tunable White, adjust the Override Color temperature for the fixture to the desired level.  

Edit_Switch_Scene.png

Click the Switch tab to add one or more (up to four) ERCs or EnOcean switches to control the fixtures. If the ERC has not already been commissioned, click the Add ERC or Add EnOcean button to add, commission, and then associate the switch to the virtual switch. Refer to the article,  Adding ERCs or Adding EnOcean.

If the physical switch has already been added and commissioned, select the ERC or EnOcean switch icon on the floor plan, click the left Left_arrow.png arrow button to add them to the table, and associate them to the virtual switch.

Edit_Switch_ERC.png

When done, click the Apply button to save the changes and close the Edit Switch Group dialog pop-up. This will take 1-2 minutes when there are many fixtures to be updated. If a fixture is powered off or rebooting after an image upgrade, the fixtures cannot be updated until they are operating normally. 

You have successfully created a switch to control a group of fixtures. Refer to the Switch Control to make sure that the switch buttons function as programmed.

Note: After creating an EnOcean switch group, atleast three sensors in close proximity to the Gateway must be enabled to SCAN mode. Refer to the instructions in Set Bluetooth Mode to enable SCAN mode.

Edit or Delete a Switch Group

From the Groups tab, select Switch, and click Edit the desired group. Make changes in the Edit Switch Group and click Apply to save edits. To delete a group, remove all fixtures or Switches from the group. Select the group fixtures in the Device tab. Click the right right_Arrow.png arrow to remove fixtures associated with the switch. Click Delete to remove the switch

Create Daylight Group

Daylight groups provide a uniform dim level across a group of fixtures for improved aesthetics. The lights are dimmed or brightened to achieve a uniform group light level in response to daylight fluctuations. Daylight groups aim to find the right balance between aesthetics, occupant comfort, and energy efficiency.

Before creating a daylight group, read the Recommended Preliminary Steps for Creating a Daylight Group.

The steps to create a daylight group are:

Step 1: Click Facilities.

Step 2: Select a Floor.

Step 3: Select Groups.

Step 4: Select sub-tab Daylight.

Step 5: Click Create. The Create Daylight Group dialog box appears.

1_Create_Daylight_Group.png

Step 6: In the Create Daylight Group box, specify a name for the daylight group.

Step 7: To add sensors to the daylight group, select the required group of sensors on the floor plan.

Step 8: Click the mceclip1.png control. The table displays the list of selected sensors. To remove sensors from the table, click the mceclip2.png control.

Note: You can select up to a maximum of 1000 sensors, and the sensors may exist across gateways. However, all sensors must be on the same floor. A sensor may only be part of a single daylight group. If the sensors already exist in another daylight group, you have the option to move the sensors to a new group or skip sensors in the group.

2_Create_Daylight_Group.png

Step 9: Choose a method for calculating the Group Light level. 

  • Average Daylight – Some fixture light levels in the group will be brighter than the Target Ambient Light Levels and some less bright. On average, the light levels will meet the targets. This is the recommended option to use.
  • Maximum Daylight – Fixture light levels will optimize for reduced energy usage. If all the sensors have the same target, then the sensor with the maximum daylight will be the sensor that dictates the Group Light Level. As daylight increases, the lights will be dimmed to the minimum required amount of light. With this setting, no occupants will have too much light, and occupants can always turn on their task lighting to increase comfort.
  • Minimum Daylight – Light levels will ensure all targets are met or exceeded. All fixtures will be set to the maximum light level required to meet all the sensors’ targets. If all the sensors have the same target, then the sensor with the minimum daylight will be the sensor that dictates the Group Light Level. That is, all occupants will have sufficient light. Choose this method in an office environment where it’s important that all occupants have sufficient light, and it’s unlikely that too much light would cause discomfort.
  • Daylight at Master Sensor – Light levels will ensure that the user-designated master sensor's light level is set to its target. In this case, the targets and ambient readings of all other sensors in the group are ignored. This method simulates more traditional lighting systems. It is a safe option only if one sensor accurately reflects the ambient readings for the group. 

Step 10: Choose Group Ambient Sensitivity.

Tip: Use a value of 5 for moderate utilization of daylight. The lights will never turn off due to daylight.

The group ambient sensitivity overrides the sensitivities set in the profile. A value of 10 will allow 100% of the Target Ambient Light Level to be provided by other light sources. A value of 0 requires that the fixtures provide the light, defeating the daylight group's purpose. Choose a value of 5 such that 50% of light may be provided by light sources other than the fixture.

Step 11: Choose the roles of each sensor.

  • Report and Act – Sensors report their ambient readings and they respond to the Group Light Level. This is the recommended option for typical office environments.
  • Report Only – Sensors only report ambient readings, but they act independently of the group and follow whatever behavior their profile dictates.
  • Act Only – Sensors do not report ambient readings, but they respond to the Group Light Level.
  • Master Sensor – If you have chosen Daylight at Master Sensor option as the method for calculating the group light level, choose a sensor from the list of sensors to be the Master sensor.  

Daylight_Master_Sensor.png Step 12: Click Apply to create the daylight group.

After creating a daylight group, it will take two to three minutes for the fixtures to adjust to a constant light level. As the amount of daylight changes, the daylight groups respond gradually over a 10 to 30-minute period. Occupants will likely not notice changes to the light levels.

Editing or Deleting Daylight Groups

From the Groups tab, select Daylight, and click Edit the desired group. Make changes in the Edit Daylight Group dialog pop-up and click Apply to save the edits. Before you delete a group, you must remove all sensors from the daylight group. In the Edit Daylight Group dialog pop-up, select sensors in the table, click the mceclip2.png control to remove sensors from the group and then click Delete.

Configure Groups

An Enlighted system can be set up easily and faster using the Configure Groups action. The Configure Groups allows you to create a switch group, motion group, apply scene template, and profile to sensors – all in one step. 

Using Configure Groups

In the left panel, select a floor, and then select the Floor Plan tab. Select the required fixtures on the floor plan, right-click, and choose to Create/Configure Groups > Configure Groups.

(Note: If you do not select a sensor, the Configure Groups option on the menu is disabled). If needed, zoom the floor plan's display and pan the display to see all the sensors in the room.

1_Configure_Groups.png

A Create Switch pop-up is displayed.

Step 1: Type a name for the Switch Group (typically, the room name is used as the switch group) in the Enter Switch Name field, and click Ok.

Note: The name specified in the Enter Switch Name field is also used as the suffix of the optional motion group's name.

2_ConfGrp_CreateSwitch.png

Step 2: An Edit screen is displayed; the various fields on this screen are explained in the following table. The selected sensors are displayed in the table. Choose the required options for the switch.

3_Configure_Groups_FloorPlan_MotionGrp.png

Field Name

Field Description

Switch Name

Enter a name for the Switch Group.

Switch type

Auto-on/Auto-off – When set, fixtures that are controlled by the switch behave as if a switch did not control them. The fixtures turn the lights to the maximum light level defined in the lighting profile when it detects motion.

Manual-on/Auto-off – When set, the fixtures behave as if a switch controls them. For example, a fixture will not turn on the light in the luminaire when occupancy is detected. Instead, the switch (or an ERC) must be used to turn on the light in the luminaire. However, for safety concerns in very low or no light situations, fixtures will always turn on the luminaire's light when occupancy is detected.

Initial time

The initial time will determine the time taken for the sensor to transition from manual or auto-on mode to auto-off when the Switch type has a value of Manual on/Auto-off or Auto-on/Auto-off.

If the initial time is set to zero, then the sensor will transition to auto-off after a period determined by [Active motion window plus Extension period (Active motion window time)], i.e., 2 x Active motion window.

If the initial time has a non-zero value, then the time taken to transition to auto-off would be Initial time plus Active motion window (extension time). If the sensor detects motion during the extension time, the sensor will transition to auto-off after an additional extension time (active motion window time) starting from that moment when the motion was detected.

Create motion group

Select this option if you need to create a motion group. All sensors in the group will behave similarly when a sensor in the group detects motion.

Motion Group name

You can change the name of the Motion Group. This field is available only if you select the Create motion group option. By default, the name is MG_Name of the Switch.

Apply Scene Template

Select this option if you want to apply a scene template to the group.

Apply Scene Template (drop-down)

Choose a scene template from the drop-down menu of scene templates. For example, the Template_20_40_60 applies three scenes where lights change from 20% to 40% and 60%.

Apply Fixture Profile

Select this option if you want to apply a profile to the fixtures in the group.

Apply Fixture Profile (drop-down)

Choose a profile from the drop-down menu of profiles.

Apply Plugload Profile

Select this option if you want to apply a profile to the plugloads in the group.

Apply Plugload Profile (drop-down)

Choose a profile from the drop-down menu of profiles.

Step 3: The Location tab is displayed by default. Here, you can position the Switch Group icon by right-clicking on the floor plan and choosing the Set Switch Position in the pop-up.

Note: The position where you right-click is taken as the position for the Switch Group icon.

4_Configure_Groups_FloorPlan_MotionGrp_Locate.png

Step 4: The Device, Scene, and Switch tabs are explained in detail in Switch Configuration Settings. Select your options accordingly.

Step 5: Click Apply to save the switch.

Create a Scene

A scene configures light levels to make the space better suited for activities. For example, in a conference room, you may want to turn off the lights directly in front of the screen to show a presentation. The lights on the perimeter of the room may be off or barely lit, and the lights directly above the viewers  set to a level bright enough to be able to take notes. 

You can create new scenes to control light levels for a group of fixtures or have them go ON/OFF with the following two programmed scenes: 

  1. All On – Sets the light level to 100% or to the current value of “Max Light Level when on” for fixtures controlled by the switch. See Understanding Profile Basic Attributes for Max Light Level when on.
  2. All Off – Sets the light level to 0% (off) for all fixtures controlled by the switch.

The two programmed scenes cannot be edited or deleted and thus are not listed in the scene list under the Scene tab. You can create additional scenes to set the light level individually for each fixture controlled by the switch. All fixtures controlled by a switch are affected when a scene is activated. 

Creating a Scene

The steps to create a scene are:

  1. Click Facilities in the left navigation panel.
  2. Select a Floor. Note that a switch is created on the selected floor and cannot be moved to another floor.
  3. Click on Groups 
  4. Click on sub-tab Switch to display the switch table.
  5. Click Create to create a new switch, or click Edit to edit an existing switch to add scenes. 

1_Create_Scene.png

  1. In the Edit Switch Group dialog box, click the Scene tab. 
  2. Under the Scene tab, click Create Scene

2_Edit_Switch_Group_Scene_.png

  1. In the Create Scene window, enter a Scene Name.
  2. Click OK. This should close the pop-up and create the scene.

3_Create_SceneName.png

  1. Select the new scene created from the scene drop-down list.

5_Scene_Added.png

Setting Fixture Light Levels for a Scene

After the scene has been created, set the light level for each fixture controlled by the switch; this is best performed by being physically under the fixtures controlled by the switch.

  1. Select the scene in the scene name drop-down list.
  2. Select fixtures on the floor plan (or in the table) that most likely will have the same light level.
  3. Adjust the light level using the slider in the Light Level boxThe light level for the selected fixtures is updated in the Light Level column of the fixture table.
  4. Configuring Tunable White: For fixtures with sensor firmware version 5.4 or lower, skip this step if the Color Value window is not displayed. If the Color Value window shows up, read the Configuring Tunable White - Recommended Prerequisites to ensure that all prerequisites are met before tuning the fixtures for Tunable White.  
    • Adjust the Tunable White color value for the fixture by dragging the slider from a warm-white to cool-white temperature in the Color Value box. The color value is updated in the Color column of the fixture table. For non-tunable white sensors, the value for color temperature appears as NA. Refer to the article Adjusting the Color Temperature for a Sensor with Firmware Version Below 5.3.
    • Continue selecting fixtures and light levels to set color values for the scene.
  5. Click the Apply button and wait for the fixtures to be updated.
  6. Click the Test Scene button and observe the lights to determine if the desired effect has been achieved until the Test Scene changes to End Test.
    If not, then select fixtures and readjust their light levels, and start back at step 2.

3_Create_Scene.png

If the desired effects change, you can later perform the above steps to readjust the fixtures' lighting. Note you can create a maximum of six scenes.

Changing the Order of Scenes

The order of the scenes in the scene name drop-down list is the same order that is displayed when you double-click a switch on the floor plan. This is also the order of the scenes on the ERCs for the switch when the ERC’s Cycle button is pressed. Use the mceclip1.png up and mceclip2.pngdown arrow buttons to change the scene order.

Switch Group Settings

The switch configuration settings are dependent on the floor plan information, such as the Location, Device, Scene, and Switches such as ERC or EnOcean that can be associated and controlled by the switch.  The steps to create or edit a new switch group are explained in the Create Switch Group.

This article provides a description of the fields for configuring the switch group settings:

 To configure any of the switch group settings for an existing switch,   

  1. Click Facilities in the left navigation panel and select a floor. Note that a switch is created on the selected floor and cannot be moved to another floor.
  2. Click on Groups and sub-tab Switch to display the switch table.
  3. Click Edit. The Edit Switch Group screen appears.

Edit_SwitchGroup.png

You can control all the switch group settings in the Edit Switch Group dialog box shown below.

1_Switch_Config.png

The Edit Switch Group includes the following attributes:

  1. Switch Name - The name of a switch based on location or function. Examples for location-based is "Board Room" or function-based is "Security Check" for a switch used for turning on lights in all areas of a floor.
  2. Switch Type - This controls the behavior of fixtures. This field supports two types of switches.
      • Auto-on/Auto-off (Default) —The fixtures turn the lights to the 'maximum light level' defined in the lighting profile when it detects motion.
      • Manual-on/Auto-off — The fixtures behave as if a switch controls them. For example, a fixture will not turn on the light when occupancy is detected. Instead, press the button on the switch to turn on the light. However, for safety concerns in very low or no light situations, fixtures will always turn on the light when occupancy is detected.
  1. Fixture Version - The sensors with firmware versions 1.x or 2.x+ controlled by the switch. The same switch cannot control sensors with firmware versions 1.x and 2.x+.

The Location Tab

The Location tab sets the location of the switch. When you right-click on the floor plan, select Set Switch Position in the pop-up window. The icon for the switch is positioned at the cursor point.

2_Switch_Config_Selectlocation.png

If needed, you can select the switch icon and drag it to reposition it on the floor plan.

3_Switch_Config_Switch_Moved.png

The Device Tab

Use the Device tab to select fixtures and plugloads controlled by the switch. Note that the selected sensors and the switch must be bound to the same gateway. Additionally, the sensors must match the firmware version specified when the switch was created in the Create Switch pop-up. For configuring a switch group, refer to the article Create Switch Group. 

Add fixtures to the table by selecting them on the floor plan and clicking the mceclip0.png control. One or multiple fixtures can be selected and moved.

4_Switch_Devicetab.png

The following image shows the fixtures added to the table, but the configuration has not yet been sent to the fixtures since the status is shown yellow.

5_Switch_FixtureStatus.png

If you need to remove fixtures from the table, select fixtures in the table or on the floor plan, and click the mceclip1.png control.

The Scene Tab

When a switch is created, the following scenes are created:

  • All On – Sets the light level to the current value of “max light level when on” for fixtures controlled by the switch. See Understanding Profile Basic Attributes for Max Light level when on.
  • All Off – Sets the light level to 0% (off) for all fixtures controlled by the switch.

Edit_Switch_Scene.png

These two scenes cannot be edited or deleted and thus are not listed in the scene list for the switch shown in the display under the Scene tab. Additional scenes should be created to set the light level individually for each fixture controlled by the switch. (Note: all fixtures controlled by a switch are affected when a scene is activated.) See Creating a Scene for the steps to set the light level individually for fixtures controlled by the switch.

The Switch Tab

There are two types of switches: ERC and EnOcean. Up to four switches can be associated with a virtual switch. Use the sub-tabs Add ERC or Add EnOcean to associate ERCs and EnOcean to the virtual switch.    

Edit_Switch_ERC.png

  • Add ERC - An ERC needs to be commissioned before it can be associated with a switch. If it has been commissioned, then it should be on the floor plan. To determine if an ERC is commissioned, tap any button on the ERC. If a single green LED blinks, then the ERC has already been commissioned. The ERC icon is shown on the floor plan after it is commissioned, as shown below.

ERC_Commission_Success.png

However, if you cannot find it on the floor plan, it has been associated with another switch. (Note: an uncommissioned ERC will have the red and green LEDs blinking when a button is tapped.)

  • Add EnOcean - An EnOcean needs to be commissioned before it can be associated with a virtual switch. Refer to the article Add an EnOcean switch. If it has been commissioned, then it should be on the floor plan.

Set Target Ambient Light Level

This article explains how to determine and set the Target Ambient Light Level. We recommend that you use this procedure under the direction of Enlighted Support

Overview

You will need to determine and set the Target Ambient Light Level during the initial set up of the Daylight Group or Daylight Harvesting. The sensor attempts to achieve the Target Ambient Light Level by adjusting its light level. The Target Ambient Light Level is also called the Ambient Threshold or Daylight Harvesting Target.

The Target Ambient Light Level of the individual sensors in the group is used to calculate the group target ambient light level, which is then compared with the group ambient reading to calculate the Group Light Level.   

You can set the Target Ambient Light Level either

  • manually or
  • automatically

Automatic calibration is preferred, but if you would like to fine-tune the lights' behavior, choose the manual method. If you are using the automatic calibration method, perform this at night and set the fixtures to a light level of 100%. Refer to the steps in Set Target Ambient Light Level.

1_SetTarget_pop-up.png

In spaces where the ambient readings vary widely at 100% light levels, the lighting designer may want to manually set the Target Ambient Light Level constant for all sensors in the Daylight group, especially when the Minimum or Maximum Daylight calculation is used.

For example, suppose a particular sensor has the lowest ambient reading in the group both at night at 100% light levels and during the day. With the Minimum Daylight method, this sensor’s low target and low ambient reading will be used for the Daylight group. The result is that there will be minimal daylight harvesting for the group.

Set Target Ambient Light Level 

The Target Ambient Light Level is the light level that the sensor attempts to achieve by adjusting its light level to determine energy savings. Energy savings are maximized by reducing the length of time a light is on, and the light's level (intensity). The procedure to obtain the best value is to perform this command when there is no ambient light (such as at night) with all lights set to full-on.

To set the Target Ambient Light level, follow the steps shown below.

  1. Select Facilities > Floor.
  2. Select all sensors or a group of sensors on the floor plan.
  3. Set the Override Light Level to ON. This turns all lights to full.
  4. With the sensors selected, right-click to display a pop-up window. In the window, select the Set Target Ambient Light Level.

2_Set_Target_Ambient_Light_Level.png

Automatic Calibration:

Perform this at night and set the fixtures to a light level of 100% before clicking the Submit button. Wait for a minute after you click the Submit button. Do not change the lights immediately to Auto mode. 

1_SetTarget_pop-up.png

Manual Calibration:

The selected sensors average, maximum, and minimum ambient readings are displayed in the Set Target Ambient Light Level window. Typically, you would choose the average ambient reading, but if you prefer darker or lighter light levels, choose maximum or minimum values, respectively. Enter the Target Ambient Light Level and click Submit.

3_Set_Target_AmbientLightLevel_Edit.png

Wait for five minutes for the data to be sent to the sensors.  The sensors dim the fixtures to maintain an ambient light level reading at the set target.

The Target Ambient Light Level may be set before or after creating a Daylight Group and may be changed at any time. Note that the targets for Act Only sensors are not used.

Recommended Preliminary Steps for Creating a Daylight Group

Daylight groups provide a uniform dim level across a group of fixtures for improved aesthetics. The lights are dimmed or brightened to achieve a uniform group light level in response to daylight fluctuations. Daylight groups aim to find the right balance between aesthetics, occupant comfort, and energy efficiency.

Recommended Preliminary Steps

Before creating a daylight group, follow the recommended preliminary steps:

Step 1: Check that all sensor firmware is version 5.1 or higher.

Step 2: Verify Transaction Fail Rate is lower than 30%. The daylight group sensors send ambient readings to Manage, and then the system calculates the Group Light Level. Hence, ensure that all sensors have adequate communication with Manage. See Viewing Network Health.

Step 3: Set Target Ambient Light Level. Generally, use the automatic calibration method to set the Target Ambient Light Level for all sensors in the group. At night, bring all the sensors to 100% dim level, and set the value automatically. Refer to the Determine and Set Target Ambient Light Level.

Step 4: Set Motion Sensitivity. Motion settings (such as Min. light level, Max. light level, Ramp-up time, Active motion window, Dim, and Linger) will continue to influence light levels. Suppose you do not want the motion to influence light levels, set Motion Sensitivity in the lighting profile to 0. See Understanding Profile Basic Attributes for details.

Step 5: To allow the Group Light Level to dim lights below the minimum light level, you may choose to set the following option in the Advanced section of the profile. See Setting Advanced Attributes.

mceclip0.png

Step 6: Assign all sensors within a daylight group to the same lighting profile. See Assigning Profile to Sensors.

Step 7: Create motion, switch, and plugload groups as needed. Motion, switch, and plugload groups continue to function independently of the daylight group. Create motion groups with the same group of sensors in the daylight groups to maintain a uniform light level. As daylight groups may span gateways and motion groups may not, it is not always possible to match them. See Working with Motion Group.

After performing all the preliminary steps, proceed to Create a Daylight Group.

Configure Advanced Daylight Groups

This article explains the capabilities of grouping fixtures for daylight harvesting for lighting designers. Engineers and technicians may also use this note to configure the Manage to satisfy a lighting design.

Create daylight groups to provide a uniform dim level across a group of fixtures for improved aesthetics.

In most cases, daylight harvesting without grouping will provide light levels that do not impact lighting aesthetics. However, occasionally lights are directed at walls or ceilings, and noticeable differences in dim levels may create undesirable patterns of light and shade on walls and ceilings. In these cases, daylight groups may be used to ensure a uniform dim level. Daylight groups are not recommended to be set for optimizing occupant comfort or energy efficiency.

The following concepts are introduced in this article:

  • Ambient Reading – The ambient light level that is measured by the sensor.
  • Daylight Group – A set of sensors that respond collectively based on the reported Ambient Readings of sensors in the group.
  • Light Level – The fixture's output light (frequently referred to as dim level by lighting professionals).
  • Group Light Level – The light output is calculated based on the ambient readings of reporting sensors in the group.
  • Target Ambient Light Level – The target ambient reading that the sensor attempts to achieve by adjusting its light level, previously referred to as ambient threshold value or daylight harvesting target.

Daylight Groups Scenarios

1. Open Office

Suppose an office with rows of pendant fixtures and large windows spaced along one wall. The pendants direct light both upward toward the ceiling and down toward occupants. The sensors point down toward the office workers to ensure ambient light levels fit for reading. Without a daylight group, the fixtures between windows may have higher dim levels than the fixtures in front of the windows. This pattern would create variations of shade and light on the ceiling if the daylight is directed toward the occupants but not at the ceiling. To provide a consistent shade on the ceiling, the light designer may want to create three rows of daylight groups with each subsequent group farther away from the window wall.

2. Office Atrium with Spotlights

Suppose an atrium with high ceilings and a few spotlights around the perimeter that are pointed at the ceiling to create indirect lighting for the office workers below. Without a daylight group, the dim levels of the spotlights would be based on the sensors controlling the spotlight. If one spotlight sensor were in the sun's direct path, the spotlight would dim, and a large area would be impacted. Similarly, the ceiling would have a hodgepodge of different shades depending on the ambient reading at each spotlight. To provide comfortable lighting for the entire group and a consistent shade on the ceiling, the light designer may want to create one large daylight group for the entire atrium.

3. Outdoor Parking Lot

Suppose an outdoor parking lot with hundreds of light poles. The parking lot is in a region where dark clouds occasionally block out the sun before sunset, creating the desire to use ambient light instead of an astronomical clock to govern lighting behavior. Without a daylight group, the fixtures would sporadically turn on as the sun starts to set, creating the false impression that the fixtures were not behaving correctly. To provide the impression that all the lights are functioning with more traditional lighting technology, a lighting designer may want to create a large daylight group. All the outdoor lights maintain a consistent dim level as the sun rises and sets.

Prerequisite Steps Before Creating a Daylight Group

1. Verify Firmware

TIP: Upgrade sensor firmware before creating a daylight group. Check that all sensor firmware is version 5.x or higher.

2. Verify Network Health

TIP: Verify Transaction Fail Rate is lower than 30%.

All sensors in a daylight group must have adequate communication with Manage. The group sensors send ambient readings to Manage, and then the system calculates the Group Light Level. Sensors that miss the command to achieve a particular Group Light Level may have different Light Levels and defeat the daylight group's purpose. Hence, ensure good network health between the sensors and the Manage.

To verify network health,

  1. Select a Floor in the facility left panel and click the Floor Plan tab.
  2. Select View > Network.
  3. Select Diagnostics > Network Health, and Metric > Transaction Fail Rate.

For a daylight group of fewer than 100 sensors, a Transaction Fail Rate lower than 30% is unlikely to result in failed transactions that would be observable by occupants. However, if the Transaction Fail Rate is substantially higher than 30%, contact Enlighted Support to address the high rate.

3. Set Target Ambient Light Level

TIP: Automatically set the Target Ambient Light Level of sensors at night with light levels set to 100%.

The Target Ambient Light Level of the individual sensors in the group is used to calculate a group target ambient light level. This group target is compared to a group ambient reading to calculate the Group Light Level.

Generally, use the automatic calibration method to set the Target Ambient Light Level for all sensors in the group. At night, bring all the sensors to 100% dim level, and set the value automatically.

Refer to the Set Target Ambient Light Level for details.

4. Create appropriate Lighting Profiles

TIP: Set motion sensitivity to 0 to ensure uniform lighting in the daylight group.

For the Office Atrium with Spotlights and Outdoor Parking Lot scenarios, motion sensitivity is usually set to 0 during time periods that are typically occupied. Late at night, it may be desirable to set motion sensitivity to a higher value if it is acceptable to have lights at the minimum light level.

For the Open Office scenario, motion sensitivity greater than zero may be desired.

In the Advanced section of the profile, you may choose whether to allow the Group Light Level to dim lights below the minimum light level. Check the highlighted option shown below to accomplish this.

 

5. Assign Lighting Profiles

TIP: Assign all sensors within a daylight group to the same lighting profile.

Manage does not require all fixtures in a daylight group to have the same profile. However, Enlighted recommends that all fixtures in a daylight group share the same profile to ensure that all sensors within a group maintain a constant dim level.

A few cases exist where lighting designers may want different profiles within the daylight group. For example, suppose a fixture in the Open Office Scenario is close to a hallway or a strong air vent. The designer may want the entire group to respond to motion but may want to create a special profile for this individual sensor to reduce its motion sensitivity.

6. Create Motion, Switch, and Plugload Groups as Needed

TIP: If motion sensitivity is desired, create motion groups with the same sensors as the daylight groups.

Motion, switch, and plugload groups continue to function independently of the daylight group. If it is desirable to have uniform group levels that vary based only on occupancy, create motion groups that match the Daylight Groups. As Daylight Groups may span gateways and motion groups may not, it is not always possible to match them.

7. Steps to Create a Daylight Group

1. Select sensors: From the Floor Plan, select sensors, right-click, and select Create/Configure Groups > Create Daylight Group.

2. Choose a method for calculating the Group Light Level.

TIP: Generally, choose the Average Daylight method.

1_Create_Daylight_Group1.1.png

  • Average Daylight: Some fixture light levels in the group will be brighter than the Target Ambient Light Level and some less bright. On average, the light levels will meet the required target light level. This is the recommended option.

  • Maximum Daylight: Fixture light levels will optimize for reduced energy usage and maximize occupant flexibility. If all the sensors have the same target, then the sensor with the maximum daylight will be the sensor that dictates the Group Light Level. As daylight increases, the lights will be dimmed to the minimum required amount of light. The method is helpful in the Office Atrium scenario if lighting designers want to rely on task lighting outside of the group. With this setting, no occupants will have too much light, and occupants can always turn on their task lighting to increase comfort.

  • Minimum Daylight: Light levels will ensure all targets are met or exceeded. All fixtures will be set to the maximum light level required to meet all the sensors’ targets. If all the sensors have the same target, then the sensor with the minimum daylight will be the sensor that dictates the Group Light Level. That is, all occupants will have sufficient light. Choose this method in an office environment where it’s important that all occupants have sufficient light, and it’s unlikely that too much light would cause discomfort.

  • Daylight at Master Sensor: Light levels will ensure that the user-designated master sensor's light level is set to its target. In this case, the targets and ambient readings of all other sensors in the group are ignored. This method simulates more traditional lighting systems. It is a safe option only if one sensor accurately reflects the ambient readings for the group.

3. Choose Group Ambient Sensitivity

TIP: Use a value of 5 for moderate utilization of daylight.
The group ambient sensitivity overrides the sensitivities set in the profile. With a value of 5, daylight will never dim a fixture to off. A value of 10 will aggressively optimize energy by utilizing daylight. A value of 0 defeats the purpose of a daylight group as daylight will have no impact on the group.

4. Choose the roles of each sensor.

TIP: Set all sensors in the Report and Act state for typical office environments.
Sensors in the group may be set to Report and Act, Report Only, or Act Only.

  • Report and Act sensors report their ambient readings, and they respond to the Group Light Level.
  • Report Only sensors only report ambient readings, but they act independently of the group and follow whatever behavior their profile dictates.
  • Act Only sensors do not report ambient readings, but they respond to the Group Light Level.

1_Create_Daylight_Group1.1.png

An Office Atrium with Spotlights pointed at the ceiling would likely require that the sensors controlling the spotlights are Act Only sensors because they may be far removed from occupied areas. So, ambient readings are not relevant. Furthermore, the designer may want to place Report Only sensors throughout the workspace. In this case, the Report Only sensors, report ambient readings from occupied areas to Manage. The system calculates the Group Ambient Light Level for the Act Only sensors to control the spotlights.

5. Click Apply to create the daylight group

After creating a daylight group, it will take two to three minutes for the fixtures to adjust to a constant light level. As the amount of daylight changes, the daylight groups respond gradually over a 10 to 30-minute period. Occupants may likely not notice changes to the light levels.

8.  View Daylight Groups

From the Floor Plan tab, select View > Daylight Group. Each group is a different color. Double click the sensor to see the sensor’s Daylight Group Name.

9.  Delete or Edit Daylight Groups

From the Groups tab, select Daylight, and Delete or Edit the desired group.

Advanced Daylight Group Behavior

Lighting behavior will continue to influence light levels. For example:

  • Switches and manual overrides will override daylight group behavior.
  • Motion and vacancy settings (Min. Light Level, Max. Light Level, Ramp-up time, Active motion window Dim and Linger, etc.) will still influence light levels.
  • Automated Demand Response, Demand Response, and Overrides will continue to function.

Daylight Group Overrides Daylight Harvesting Profile Settings

When a sensor belongs to a daylight group, the group behavior overrides most of the daylight harvesting settings in the sensors’ profile. The table below describes the parameters used for daylight group behavior instead of the parameters defined in the daylight harvesting profile.

Field Daylight Harvesting   Daylight Group
Profile Settings
1. Ambient Sensitivity Ignored Group Ambient Sensitivity value is used
 Advanced Profile Settings
1. Adjust fixture light levels when ambient light levels drop by X __ (%) or rise by Y__ (%) Ignored Values are replaced with

2. Only change fixture light level after change in ambient light level is stable for __ seconds.   A brief dramatic decrease in ambient readings that affect the entire group may cause light levels to be increased. A dramatic increase in light levels needs to be maintained for at least 20 seconds before the change will impact lights.
