(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 begins in the heating operation. If the room temperature exceeds the setting temperature by
2ºC or more, the unit checks the room temperature at 5-minute intervals and, depending on the result, determines the range
of heating oriented dehumidifying operation within the (M) range.

seconds, determines the operation mode and the room temperature setting correction value, and then begins 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 control and the setting temperature.
