HC-MPU Battery
The battery sustains volatile information when the power is off. Controller operating parame-
ters are stored in non-volatile memory and will not be affected by battery removal. The battery
provides 3.3 VDC. If battery voltage falls below 2.2 VDC, the battery should be replaced. If bat-
tery replacement is part of a regular maintenance schedule, we recommend it be replaced every
two years.
Replacement:
1. Shut down power to the controller.
2. Replace the battery on the HC-MPU board.
3. Restore controller power.
4. Reset date and time. Please refer to “Date/Time, View / Adjust” on page 4-63.
