I Single Package Heat Pumps
Thermostat Fan Switch Operation
With the thermostat fan switch in the ON position, the circu-
lating air blower will run continuously.
With the thermostat fan switch in the AUTO position, the
circulating air blower will only run during a cooling or heat-
ing cycle and when the electric heat accessory is required if
the electric heat accessory is installed.
Adjusting RoomTemperatures
Ifthe temperature in individual rooms is not as desired, bal-
ance the system by adjusting the dampers in the branch
ducts. Adjust a little at a time and wait a day after each
change to judge the effect. Once the dampers are adjusted
for normal weather conditions, it is best to leave them that
way. Compensate for temporary weather changes by ad-
justing the thermostat setting.
