Replacing ERC Battery

Overview

This article describes the steps for changing the battery on an Enlighted Room Control Switch. 

When the red or green LEDs on the ERC do not flash when a button is pressed, it’s time to replace the battery. The ERC uses a standard CR2032 battery that is accessed after opening the case.

Depending on the ERC model number, refer to the corresponding section:

If the ERC is mounted on a wall or a junction box:

1. Remove the cover face-plate.

2. Using an appropriate screwdriver, remove the four mounting screws turning each one counterclockwise.

3. Remove the switch compartment cover and gently pull the ERC switch from the mounting frame.
4. Insert a flat-head screwdriver into the notch provided between the cover and backplate of the ERC.

5. Applying light pressure on the back case, open the front side. Gently pull the front case away from the backplate. The battery is accessed after opening the case.
6. Slide the old battery from its compartment using the flat head of the screwdriver. Be sure to dispose of used batteries in an environmentally friendly manner.

7. Insert the new battery with the “+” or logo facing up (away from the circuit board).
8. Replace the front case with the backplate.
9. Using the four screws, re-mount the ERC into the compartment cover and snap on the cover face-plate.

8. Using the screws, re-mount the ERC into the compartment cover and snap on the cover face-plate.

FAQs

What is the expected battery life of the ERC?

Battery life depends on how often the ERC is used. We estimate multiple years of battery life based on normal office usage. 

When you replace a battery, do I need to reprogram the switch?

No, you need not reprogram the switch.    

How do you know when the battery is low?

When you press any button in normal operation, and when the flash turns red, it means that the battery is low. See the ERC Installation guide for LED status indicators.
