14.20 Compressor Reverse Rotation Protection Control
•
If the compressor is operating continuously for 5 minutes or longer and the temperature difference between
intake air and indoor heat exchanger is 2.5°C (cooling mode)/5°C (heating mode) or less for continuous 2
minutes, compressor will stop and restart automatically.
•
Time Delay Safety Control is activated before the compressor restart.
▲ T = Indoor heat exchange temperature - Intake air temperature (heating mode)
▲ T = Intake air temperature - Indoor heat exchanger temperature (cooling mode)
•
This is to prevent compressor from rotate reversely when there is an instantaneous power failure.
•
If this condition happens continuously for 5 times within 50 minutes, unit will turn OFF with TIMER LED blinks.
•
The 5 Times counter can be reset when either one of the following condition happen:
o
Unit is OFF by remote control or AUTO OFF/ON button.

o
Fan speed is at Lo or QLo.
o

o
Compressor is continuously running.
•
Fan speed, angle of horizontal louver (vertical airflow angle) and angle of vertical louver (horizontal airflow angle)
will be adjusted accordingly in this control.
o
Fan speed will be increased slowly if the unit is in quiet mode and Lo fan speed.
o
The angle of horizontal louver will be changed as table below:
