2) When any one of below conditions meet, the function cancel:
a Indoor coil temp. rise to 10
℃
;
b Ta is equal or lower than set temperature;
c The unit stops or working mode changed.
Note: Anti frosting temperature changes from +1
℃
to -3
℃
.
2.2.5 Indoor evaporate anti frosting function
:
Auto operate
: When the compressor works for 3 minutes, if indoor coil thermistor is equal or lower than -15
℃
,
and this last 3 minutes, this protection function starts automatically.
Operate period
: The compressor will stop for 6 minutes, and then restart, within 6 minutes of the compressor’s
working, if this happen again, the unit will stop and trouble indicator signal will show.
Indoor fan control
: choose fan speed through the indoor panel, when the outdoor unit is under abnormal
inspection period, fan speed is always in low flow.
Swing louver control
: the swing louver is controlled through indoor panel.
Outdoor unit abnormal inspection
: the compressor continues working for 3 minutes, indoor coil temperature
is at least lower 5
℃
than room temperature, if this difference do not last for one minute, indoor fan will
change into low flow automatically. After 5 minutes, if the difference is still not in this range, it means
outdoor unit is abnormal, and then the compressor will stop. This period will show on panel.

.2.6 Over heat protection: see page 47 outdoor unit control. If outdoor coil temperature rise to 68
℃
, the indoor coil
temperature will remain a lower temperature: 7-12
℃
3. Dehumidifying mode
3.1 Temperature control: the same as cooling mode
3.2 The compressor control:
3.2.1 Compressor 3 minutes protection: the same as cooling mode
3.2.2 When in inspection function, the compressor stops.
3.2.3 When room temperature is lower than 18
℃
, dehumidifying mode don't work, when room temperature is
higher than 10
℃
, the compressor will begin a intermittent work, the working or stop time is decided by Rt.
(Rt = Ts – Ta) ( The compressor should have worked for 3 minutes at least.)

and high than Ts, the compressor will stop for 3 minutes.
e Ta is equal or higher than Ts, the compressor will stop for 10 minutes.
3.3 Indoor fan control:
When the compressor works, indoor fan is in low flow mode, and the air flow can not change by the panel, when
the compressor stops, indoor fan stops.
3.4 Swing louver:
The action is the same as in cooling mode. When the compressor stops, the swing louver also stops.
3.5 Outdoor unit abnormal inspection: in dehumidifying mode, this function do not work.
