Condition of ending defrosting:
If any one of following items is satisfied, defrosting will stop and the machine will turn to normal heating
mode.
① The defrosting time achieves 10min;
② T3 ≥15℃;
③ T3 ≥7℃ for 60seconds.
1.3.3.5 High evaporator coil temp.T2 protection:
For 12k models：
----T2> TEH2℃, the compressor running frequency decreases to the lower level every 20s.
When the frequency decreases to F2 and the T2 is still over TEH2℃ for 3 minutes, the compressor will
stop.
----T2<48℃ or TEH2℃<T2<48℃ for 6 minutes , the frequency will not be limited.
----T2>60℃, the compressor will stop and restart when T2<48℃.
Console 18k：T2>63℃, the compressor will stop and restart when T2<52℃.
For other models: T2>60℃, the compressor will stop and restart when T2<54℃.
1.3.4 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 ∆T (∆T =T1-Ts).
For 12k models:
∆T=T1-Ts Running mode
∆T＞1℃
