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
ΔT＞1℃
-1<ΔT≤1℃
ΔT≤-1℃
Indoor fan will run at auto fan of the relevant
mode.
