Adjusting Room Temperatures
If the 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 .
