Adjusting the Dehumidification Setpoint

Adjusting the Dehumidification Setpoint
Dehum Terminal: If a MISC terminal is selected for DEHUM operation
(see page 10.2), then the thermostat will provide power to this terminal
when the humidity in the building is above the setpoint you have chosen.
See page 10.6 for detailed programming instructions. To utilize this
feature your HVAC unit must be equipped with a DEHUM terminal.
Cool to Dehumidify: If the thermostat is programmed for Cool to
Dehumidify operation, then the thermostat will energize the cooling
system any time the humidity in the building is above the setpoint you
have chosen. See page 10.4 for detailed programming instructions.
In each case, when the indoor humidity falls below the setpoint you
have selected, Cool to Dehumidify and the MISC terminal will be
de-energized. The value for this setpoint ranges from 25% to 99%.
NOTE: Due to variations in environmental conditions, it is not always
possible to achieve the desired humidification or dehumidification setpoint.

5% differential is forced between the humidify and dehumidify setpoints.
