Commercial No This option ensures that the compressor runs
long enough to effectively reduce humidity
when the cooling equipment is cycled on. The
compressor will run for the "minimum on time"
you set until the desired humidity level is
reached.
Commercial No The thermostat uses the cooling system to
reduce humidity by lowering the temperature
up to 5° F below the current cool setpoint until
the desired humidity level is reached.
The thermostat keeps the temperature below
the cooling setpoint until the desired humidity
level is reached.
Both No This ISU is only displayed when ISU 9000
Dehumidification Equipment is set to

Click boxes on screen to select which system
modes allow dehumidification. If a box is NOT

Auto mode, the thermostat will allow
dehumidification if the last call was for cool.

when the system setting is Off.
