runs long enough to effectively reduce
humidity when the cooling equipment is
cycled on. The compressor will run for the

desired humidity level is reached.

reduce humidity by lowering the
temperature up to 5° F below the current
cool setpoint until the desired humidity
level is reached.
The thermostat keeps the temperature
below the cooling setpoint until the desired
humidity level is reached.
