In Dry Mode, the unit operates in a mild cool mode to lower the humidity of the room. In order to
maintain a high efficiency in the drying operation without over lowering the room temperature excessively,
the Dry Mode is different from the Cool Mode in two ways.
1. The IFAN is forced to operate at low speed only. And, the IFAN is turned off with the COMP.
2. The unit operates in either the “Dry-on” state or the “Dry-off” state. If RT = SPT, the unit will operate
in “Dry-off” state. The COMP is forced to operate for 6 min after it has stopped working for 15 min.
If RT > SPT, the unit will operate in “Dry-on” state. The COMP is forced off for 3.5 min after it has
been working for 15 min.
Note 1: COMP is forced off in Dry-on state.
Note 2: COMP is forced to operate in Dry-off state.
7-5 Fan Mode Operation
In Fan Mode, the indoor fan is turned on to improve the air circulation in the room. COMP and OFAN
remain OFF all the time.
Note: If the user has selected the Auto Fan Speed setting, the IFAN speed would be selected by the unit
automatically according to the difference between RT and SPT, as in Cool Mode.
