OPERATION
System Selector Switch
The System Selector switch on the front of the thermostat determines the operating
mode of the thermostat. You may select COOL, OFF, HEAT.
NOTE:
Anytime you install or remove the thermostat from the wallplate,
slide the System Selector to the OFF position to prevent the possibility
of a rapid system On-Off.
Fan Switch
The Fan switch should normally be located in the AUTO position. The Fan will be
turned on along with normal operation of your system. In a normal gas or oil furnace,
the Fan will be turned on by your furnace after its warm-up delay. For electric heat, air
conditioning, and heat pump operation, the Fan will turn on with the system.
To run the Fan on continuously, slide the Fan switch to the ON position.
