HUMIDITY 
To adjust the thermostat's humidify and dehumidify setpoints:  
•  Drag the wheel up or down  
•  Tap the top of the wheel to decrease the setpoint by 1% 
•  Tap the bottom to increase the setpoint by 1%.  
 
If cooling equipment is not available, COOL TO DEHUMIDIFY is not adjustable on the thermostat and the blue 
Dehum Setpoint wheel is not adjustable. 
HUMIDIFY — not adjustable on the thermostat (the orange Hum Setpoint wheel is not adjustable) unless 
configured to use one of the following outputs: 
•  O/B 
•  Y3 
•  W2 
 
DEHUMIDIFY = YES — When humidity is above the dehumidify target, the cooling setpoint is adjusted downward, 
increasing cooling demand, according to the equations in the following table, when you select YES for 
DEHUMIDIFY (not true for OVERCOOL (2) or HUMIDIMIZER selections). 
Use the cooling setpoint only 
Cooling setpoint = Cooling Setpoint – (Cooling Setpoint - 70°F) x (Dehumidify 
Error / 10) with maximum dehumidify Error of 6% (i.e. use 6% if >6%) 
Cooling setpoint = Cooling Setpoint – (Dehumidify Error / 2) with maximum 
dehumidify Error of 6% 
 
When cooling to dehumidify, the minimum ON timer increases to 5 minutes and the second stage (or greater) is 
not started unless there is also a cooling demand.  
OVERCOOL 2° commands the system to operate the compressor, within limits, when there is a dehumidification 
demand, even if there is no cooling demand. The system may overcool up to 2°F and no more, when satisfying a 
dehumidification demand. 
 
Humidi-MiZer™ 
When configured as a HUMIDIMIZER output, and the humidity level is above the dehumidify target, 24V is output 
at the selected terminal. When the humidity level is below the dehumidify target, 0 Vac is output on the selected 
terminal. There is a +1/-4% hysteresis around the dehumidify target to prevent rapid on/off cycling of the selected 
output. 
This output may be connected to compressor outputs on commercial equipment. If the selected output is 
energized without any compressors being energized, the 5-minute time guard must be enforced.
