POWER & RESET OPTIONS
The equipment control module is powered from
24VAC. The thermostat is powered from the equipment
interface module and has a battery back-up option for
the clock.
The thermostat has a memory backup that saves the
thermostat settings in case of a power interruption.
The system settings will be retained but the clock will
reset after 90 seconds with no battery or equipment
control module power.
The reset button located under the battery cover can
be used to reset the thermostat to factory defaults. The
system settings will also be reset to default.
