8.4.3.5 Evaporator coil temperature protection
----T2> TEH2
℃
, the compressor running frequency decreases to the lower level and runs for 20s.
When the frequency decreases to F2 and the T2 is still over TEH2
℃
for 3 minutes, the compressor
will stop.
----T2<48
℃
or T2 stays in 48
℃
~ TEH2
℃
for 6 minutes, the frequency will not be limited by T2.
----T2>60
℃
, the compressor will stop and restart when T2<48
℃
.
8.4.4 Auto-mode
This mode can be chosen with remote controller and the setting temperature can be changed between
17~30
℃
.
In auto mode, the machine will choose cooling, heating or fan-only mode according to ΔT (ΔT =T1-Ts).
ΔT=T1-Ts
Running mode

Cooling
-1<ΔT≤1

Fan-only
ΔT≤-1
℃
Heating
Indoor fan will run at auto fan of the relevant mode.
The louver operates same as in relevant 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.
8.4.5 Drying mode
8.4.5.1 Indoor fan speed is fixed at breeze and can’t be changed. The louver angle is the same as
in cooling mode.
