1.Normal Dehumidify Operation

When normal dehumidify is selected, the compressor will not turn on without a cooling demand. If dehumidify demand exists while cooling, dry contact will also be active (24VAC removed). This output commands variable-speed blowers to reduce their airflow, which improves water re- moval from the cooled air.

2.Cool to Dehumidify

The cool to dehumidify selection tells the system to operate the compres- sor, within limits, when there is a dehumidify demand even if there is no cooling demand. The limits are that the system may overcool up to 3_F, but no more, while attempting to satisfy a dehumidify demand. Within this 3_F range, there is an additional balance between overcooling and humidity satisfaction. When overcooling must occur, the dehumidify set- point is adjusted upward by 2% per degree of overcooling. For example, a cooling setpoint of 76_F and a dehumidify setpoint of 60% is equiva- lent to a cooling setpoint of 75_F and a dehumidify setpoint of 62%. This dehumidify setpoint change is internal to the Thermidistat Control and is not shown on the display.
