Programming the Thermostat

IMPORTANT: With Adaptive Intelligent Recovery™,

program the times for when the homeowner wants
the home comfortable. The thermostat will decide
how early to begin the temperature changes.

NOTE: Some models will show 32

°

F instead of the

current temperature, indicating the thermostat is op-
erating on backup batteries until the thermostat is
mounted on the wallplate and the system is powered.
