PRINCIPLE OF OPERATION
When the room temperature is below the set point,the variable-speed
fans can operate according to a minimum ventilation cycle. Running the
fans even though ventilation is not required for reducing room tempera-
ture is useful to reduce humidity levels and supply oxygen to the room.
It also prevents the fans from freezing in winter.
