Thermostat Fan Switch Operation

lating air blower will run continuously.
With the thermostat fan switch in the AUTO position, the cir-
culating air blower will only run during a cooling or heating
cycle and when the electric heat accessory is required ifthe
electric heat accessory is installed,
Adjusting Room Temperatures
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.
