will enter the defrosting mode.
After the compressor starts up and keeps
running, mark the minimum value of T3 from the
10th minutes to 15th minutes as T30.

.
Condition of ending defrosting:
If any one of the following items is satisfied, the
defrosting will finish and the machine will turn to
normal heating mode.

If the machine switches mode between heating
and cooling, the compressor will keep stopping
for 15 minutes and then choose mode
according to T1-Ts.
If the setting temperature is modified, the
machine will choose running function again.
6.4.5 Drying mode
Indoor fan speed is fixed at breeze and can’t be
changed. The louver angle is the same as in
cooling mode.
All protections are active and the same as that in
