Dehumidifying With The DEHUM Terminal*

Dehum  Terminal: 

To  control  a  MISC  output  for 

dehumidification,  place  the  MISC1,  MISC2,  or 
MISC3  jumper  on  the  terminal  labeled  DEHUM.   
This  will  supply  24VAC  to  the  selected  MISC 
terminal when the humidity in the home is above the 
setpoint you have chosen.   Only one of the three 
outputs  (MISC1,  MISC2,  or  MISC3)  is  req-
uired  to  have  a  jumper.   

For  more  information 

regarding the MISC1, MISC2, and MISC3 outputs, 
please  consult  your  thermostat  Owner’s  Manual.

When the indoor humidity falls below the setpoint 
you  have  selected,  the  MISC  terminal  will  be  de-
energized.   The value for this setpoint ranges from 
25% to 99%.  To utilize this feature your HVAC unit 
must  be  equipped  with  a  DEHUM  terminal.

  For 

more information regarding dehumidification using 
the  DEHUM  terminal,  please  consult  your 
thermostat’s Owner’s Manual.

  

*Dehumidifying with the DEHUM terminal  may not be available 
  with your thermostat model number.  Please consult your 
  Owner’s Manual for details.
