Humidity Control Adjustment
To maintain optimum humidity control without causing
condensation on cold surfaces such as windows, the
homeowner must adjust the setpoint as the outdoor
temperature changes.
To reduce relative humidity, reduce the setpoint
approximately 3% RH humidity every 24 hours. To
increase relative humidity, increase the setpoint
approximately 3% RH every 24 hours.
Setpoint Adjustment
Set the humidity setpoint according to the prevailing
outdoor temperature. See Table 1 for recommended
settings.
