Dehumidifying With Air Conditioning*

Cool to Dehumidify:

   If Cool to Dehumidify is on 

and the Humidity Module is installed, the thermo- 
stat  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 . 

 

For Example:  If the cooling overshoot is set for 3 F and 
the cooling setpoint is set for 74 F, then as long as the 
room  temperature  reads  between  71 F  and  74 F  this 
feature  will  energize  the  compressor  and  fan  to 
dehumidify the air. 

When the indoor humidity falls below the setpoint 
you have selected, the Cool to Dehumidify function 
will  be  de-energized.    The  value  for  this  setpoint 
ranges  from  25%  to  99%.   

For  more  information 

regarding dehumidification using the air conditioner, 
please consult your Owner’s Manual.
