Operation
Setting Fan and System Switches
Fan and System settings are controlled manually by
using the switches located at the bottom of the
thermostat case. See Fig. 11.
FANSWITCH
Fan switch settings are:
On: The fan runs continuously. Use for improved air
circulation and air quality.
Auto: Normal setting for most homes. In cooling, the
fan starts and stops with the cooling equipment. In
heating, the fan is controlled directly by the heating
equipment and may start a few minutes after the
heating equipment turns on (most systems). When
the fan operation (fuel) switch is in the E position,
the fan starts and stops with the heating equip-
ment.
Slide the Fan switch in the lower left corner of the
thermostat to select the desired fan setting.
SYSTEMSWITCH
System switch settings (see Fig. 11) are:
Cool: The thermostat controls the cooling system.
Off: Both heating and cooling are off.
Heat: The thermostat controls the heating system.
Slide the System switch in the lower right corner of the
thermostat to select the desired system setting.
