OPERATION

8This system operates on your system’s 24 Volt power supply. The supply is monitored by the thermostat, and it will stop functioning if AC power is lost. (When using backup batteries, “No AC Pwr” will be displayed.) All system controls will remain

off until power is restored.

NOTE: The INDIGLO® Night-Light will not function when AC power is lost.

NOTE: Any remote temperature sensors (if used on your system) will not operate when AC power is lost.

BATTERY WARNING

9Batteries may be used optionally to prevent the loss of your thermostat’s clock, programs and options due to a power outage. However, when the batteries become drained, a low battery warning will appear on the display. When this message occurs, install 2 new AAA batteries. You have approximately 30

seconds when changing the batteries to keep thermostat’s clock and program settings.

NOTE: The default system selection at power-on is HEAT. Batteries are recommended to prevent an undesired system change due to a power outage.
