- The unit will heat in the heat pump mode in ambient temperatures above approx. 45°F. The furnace will
automatically engage at ambient temperatures below approx. 45°F.
MODE - DRY

additional cooling is not required.

- Set the temperature to desired set point. Note: the fan speed is locked in LOW.
- The compressor will cycle on and off at approximate intervals of 6 minutes to extract moisture from the air.

- The unit can provide no dehumidification if the room temperature is below 64°F (18°C).
