5) Congratulations, the furnace, air conditioner or heat pump and thermostat will
now work together to bring you all the benefits of Ideal Humidity System®
Technology.
Furnace Dehumidification with Performance Furnaces
Enhanced dehumidification is achieved by reducing the blower speed to 90% of the
cooling blower speed during a call for dehumidification. You can also choose to use
Cool to Dehumidify and set the cooling off delay to 0 to prevent re-evaporating water on
the coil after a cooling cycle.
When the call for cooling is satisfied and there is a demand for dehumidification, the
cooling blower-off delay is decreased from 90 seconds to 5 seconds. If unit is in
continuous fan, there will not be an off delay.
