4.8 Outline of drying operation
(1) After the fan commences operation (1st speed for indoor fan, 3rd speed for outdoor fan) within
20 seconds after the start of operation, the room temperature TION, the outdoor air temp. sensor
TO and set temperature SP are checked to determine whether to use cooling & drying or heating
& drying.
● TION > SP-3 or TO ≥ 19℃: cooling & drying
● TION ≤ SP-3 or TO < 19℃: heating & drying
Cooling & drying or heating & drying is selected again one hour after selection.
(2) Outline of control
(a) Cooling & drying
● Room temperature TION, set temperature SP and value of humidity sensor are checked
every 5 minutes after the cooling & drying is selected to determine the operation range of
drying.
● Operation ranges are shown in the table below:

● When the set temperature change signal is received, the original range will be continued till
finished; in the next 5 minutes, the room temperature TION, set temperature SP and value
of humidity sensor are checked to determine the new operation range.
● When a range other than Range I is switched to Range I, the control is as follows:
