Backup battery replacement
The internal backup battery should be replaced approx. every 5-7 years. Replace the battery, if the
alarm Low BackupBatt occurs. Follow these instructions:
1. Disconnect all terminals from the controller and remove the controller from the switchboard.
2. Release the rear cover using a flat screwdriver or another suitable tool.
3. Remove all plug-in modules.
4. The battery is located in a holder on the circuit board. Remove the old battery with a small
sharp screwdriver and push with a finger the new battery into the holder. Use only CR1225
lithium battery.
5. Put the rear cover back. Use slight pressure to lock the snaps into the housing. Pay attention
that the cover is in correct position and not upside down!
6. Plug the modules back into the slots.
7. Power the controller on, adjust date and time and check all setpoints.
