If it is detected that the low-pressure switch is off when the compressor is stopped, the complete unit will be stopped,
E3 will be displayed and the unit cannot be restarted automatically. You have to press ON/OFF key to switch off the
unit and press this key again to restart.
7.1.5.4 Exhaust Pipe High-temp. Protection
After the compressor is started, if the exhaust temperature is too high or exhaust sensor is in short circuit (or open
circuit), the unit will be stopped when the indoor ambient temperature reaches the preset value.
After the compressor is stopped for 3 minutes, the complete unit will be restarted when the exhaust temperature is
resumed to normal.
In case of above issue, the complete unit cannot resume its operation and E4 will be displayed. You have to press
ON/OFF key to switch off the unit and press this key again to resume operation under preset mode.
7.1.5.5 Indoor Overtemperature Protection
If it is detected that the evaporator tube temperature is too high under heating mode, the outdoor fan will be stopped.
When the evaporator tube temperature resumes to normal, the outdoor fan will be started.
7.1.5.6 Low-voltage Protection
If the current is detected over 22A as the compressor is started, the unit will be stopped when indoor ambient
temperature reaches preset value. The compressor will automatically resume to its original operating status after it is
stopped for 3 minutes. If E5 is displayed, the compressor cannot resume to its original operating status automatically,
in which case you have to press ON/OFF key to switch off the unit and press this key again.

7.1.5.8 Compulsory Cooling (Heating) Mode
If no valid key-press upon first energization:
①
From the remote controller, you can press temperature selection key (+) to enter into compulsory heating mode, in
which case all the keys on front panel and remote controller will be shielded, all loads will be started and the indoor
fan will run at high speed. If it is detected that ambient temperature is in open circuit or higher than 105 , or that
℃
evaporator temperature is in open circuit or higher than 105 , the buzzer will beep. After five minutes, the unit will be
℃
stopped and enter into normal standby status.
②
From the remote controller, you can press temperature selection key (-) to enter into compulsory cooling mode, in
which case all the keys on front panel and remote controller will be shielded, all loads except the 4-way valve will be
started and the indoor fan will run at high speed. If it is detected that ambient temperature is in open circuit or higher
than 105 , or that evaporator temperature is in open circuit or higher than 105 , the buzzer will beep. After five
℃
℃
minutes, the unit will be stopped and enter into normal standby status.
The functions stated in 1 and 2 are only for test purpose. Compulsory heating function is not available for cooling-only
unit.
7.1.5.9 Indicator
Power indicator: It is bright when energized and black when de-energized. It will blink under indoor antifreeze
protection, compressor high-pressure protection, low-voltage protection and defrosting.
Cooling indicator: It is bright under cooling mode, dehumidifying mode, auto cooling mode or auto dehumidifying
mode. It is black under other modes.
Heating indicator: It is bright under heating mode and auto heating mode. It is black under other modes
7.1.5.10 Power-OFF Memory Function
Memory function includes the mode, swing, preset temperature, preset fan speed, Auto ON/OFF (If the power is cut off
before the preset time for AUTO ON/OFF, the timer will count the time again once the power is resumed. If the power is
cut off after the preset time for AUTO ON/OFF, the unit, once energized again, will run under the mode after preset AUTO
OFF time).
Once energized again after any de-energization, the unit can be automatically restarted according to the memory.
