8.4.3.5 High evaporator coil temp.T2 protection:
(1) T2> TEH2 , 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.
(2) If T2<48 or T2 stays in 48~℃℃ TEH2 for 6 minutes, the frequency will not be limited by T2.℃
(3) If T2>60, the compressor will stop and restart when T2<48.℃℃
While TEH2=53℃ for 9k,12k,18k models, TEH2=55℃ for 24k model..
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
ΔT＞1℃
Cooling
-1≤ΔT≤1℃ Fan-only
ΔT<-1℃ Heating
Indoor fan will run at auto fan of the relevant mode.The louver operate 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 rechoose mode according to T1-Ts.
If the setting temperature is modified, the machine will rechoose running function.
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.
