Using Your Air Conditioner to Dehumidify

the thermostat has the ability to initiate a cooling cycle for advanced
dehumidification operation. When the thermostat detects the humidity
percentage is above the setpoint for dehumidification, and heating or
cooling is not on, the thermostat will force the compressor to run with
the fan, thus reducing moisture in the air. The green LED will blink
once every eight seconds to indicate this is taking place. This feature
will also allow you to adjust the cooling overshoot of the setpoint, from
0 to 5 (adjustable in step #11). ° °
set for 3 F and the cooling setpoint is set for 74 F, then as long as the room °

compressor and fan to dehumidify the air.
