8.4.3.5 High evaporator coil temp.T2 protection:
(1) T2> TEH2, compressor running frequency decreases to the lower level every 20s. If the frequency
decreased to F2 and the T2 still over TEH2 for 3 minutes, the compressor will stop. If T2 deceased to
lower than 48, or 48<T2< TEH2 last for 6 minutes, release the frequency limit control.
(2) If T2>60, stop the compressor and restarts until T2<48.

8.4.4 Auto-mode
This mode can be chosen by 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 the difference
between T1 and Ts.
T1-Ts Running mode
T1-Ts＞1
Cooling
-1< T1-Ts≤1 Fan-only
T1-Ts≤-1 Heating
Indoor fan will run in auto fan of the relevant mode.
The louver operates the 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 the mode according to T1-Ts again.
If the setting temperature is modified, the machine will choose the running function again.
