STEP 7 Adjust Fan Operation Switch, As Required
■
The thermostat fan operation switch is fac-
tory-set in the NON ELEC position. This is the
correct setting for most systems. If your system
is an electric furnace, set the switch to the
ELEC position. The ELEC position will allow the
fan to turn on immediately with the heating or
cooling system if the G terminal is connected to
a fan relay.
NOTE: Either the switch must be set before the
batteries are installed, or the left battery
must be removed to access the switch.
