If the Battery Dead alarm occurs, the controller displays an

alarm message and the global alarm output turns on. Ac-

knowledging the alarm restores all settings to factory defaults

and turns off the global alarm output.

CAUTION!

Acknowledging this alarm restores all setting

NOTE!

The controller retains its settings when pow-

not powered.

1. Replace the controller.

2. Using your record of controller settings, re-enter your

settings.
