User Manual

Possible Cause: The unit is not set to Heating mode.
Solution: Press the MODE button until the HEAT icon is displayed.
Possible Cause: The set temperature is too low.
Solution: Set the air conditioner to a higher temperature. The unit has a 5°F temperature
cushion; the unit will heat until the ambient temperature reaches within 5°F of the set
temperature.
Possible Cause: The internal water reservoir is full – Red light is flashing, STOP or P1 appears
on the display.
Solution: “Drain the collected condensation from the lower drain port or turn the pump feature
on (applicable models). Note: some models have a rubber stopper and others have a plastic drain
cover and rubber stopper. Refer to the user manual for more information. It is normal for the unit
to collect more condensation and need to be drained more often than it does in Cool mode as the
self evaporative feature does not engage in Heat mode.
If after draining the red light is flashing, STOP or P1 still appears on the display, there may be a
loose internal connection. Please contact Whynter Customer Support for service. ”
