(ii) Heating oriented dehumidifying
After interrupting the compressor operation for 3 minutes (by the 3-minute timer) following the determination of
heating oriented dehumidifying, the unit enters in the heating operation. If the room temperature exceeds the setting
temperature by 2ºC or more, the unit checks the room temperature at 3-minute intervals and, depending on the result,
determines the range of heating oriented dehumidifying operation.

Notes (1) Protective function will actuate with priority even during the continuous mode.
(2) If the "Room temperature setting" is changed to 18~30ºC during the continuous dehumidifying operation, the unit enters in
the cooling oriented dehumidifying operation.
(8) Outline of automatic operation
(a) Determination of operation mode
The unit checks the room temperature and the outdoor air temperature after operating the indoor and outdoor blowers for 30
seconds, determines the operation mode and the room temperature setting correction value, and then enters in the automatic
operation.
Room temperature (˚C)
(b) The unit checks the temperature every hour after the start of operation and, if the result of check is not same as the previous
operation mode, changes the operation mode.
(c) When the unit is started again within one hour after the stop of automatic operation or when the automatic operation is
selected during heating, cooling or dehumidifying operation, the unit is operated in the previous operation mode.
(d) Setting temperature can be adjusted within the following range. There is the relationship as shown below between the signals
of the wireless remote controller and the setting temperature.
