Move the switch to the proper setting:
Gas or Oil: For gas or oil heating systems, leave the fan
operation switch in this factory-set position (for systems that
control the fan in a call for heat).
Electric or Heat Pump: Change the switch to this setting
for heat pump or electric heat systems. (This setting is for
systems that allow the thermostat to control the fan in a call
for heat, if a fan wire is connected to the Gterminal.)
