During cooling operation: compres-
sor will stop while indoor fan will
operate.
During heating operation, the com-
plete unit stops.
During cooling and drying opera-
tion, compressor will stop while
indoor fan will operate; During
heating operation, the complete
unit will stop
All loads operate normally, while
operation frequency for compres-
sor is decreased
Wireless remote receiver and but-
ton are effective, but can not dis-

When the outdoor unit receive sig-
nal of Gathering refrigerant
,the system will be forced to run
under cooling mode for gathering
refrigerant
During cooling and drying opera-
tion, indoor unit operates while
other loads will stop; during heating
operation,
the complete unit will stop opera-
tion.
AC stops operation once reaches
the setting temperature. Cooling,

A/C status Possible Causes
Possible reasons:
1. Refrigerant was superabundant;
2. Poor heat exchange (including
fifth blockage of heat exchanger
and bad radiating environment );
Ambient temperature is too high.
1. Poor air-return in indoor unit;
2. Fan speed is abnormal;
3. Evaporator is dirty.
1. In defect of refrigerant;
2. Indoor evaporator temperature
sensor works abnormally;
3. The unit has been plugged up
somewhere.
Please refer to the malfunction
analysis (discharge protection, over-
load).
1. Supply voltage is unstable;
2. Supply voltage is too low and
load is too high;
3. Evaporator is dirty.
Refer to the corresponding malfunc-
tion analysis.
Refer to the malfunction analysis
(overload, high temperature resis-
tant).
Replace outdoor control panel AP1
Discharging after the complete unit
is de-energized for 20mins, check
whether the thermal grease on IPM
Module of outdoor control panel AP1
is sufficient and ahether the radiator
is inserted tightly. If its no use, please
replace control panel AP1.
1. No jumper cap insert on main
board.
2. Incorrect insert of jumper cap.
3. Jumper cap damaged.
4. Abnormal detecting circuit of
main board.
Nominal cooling mode
1. Loosening or bad contact of
indoor ambient temp. sensor and
main board terminal.
2. Components in main board fell
down leads short circuit.
3. Indoor ambient temp. sensor
damaged.(check with sensor
resistance value chart)
4. Main board damaged.
1. Loosening or bad contact of
Indoor evaporator temp. sensor
and main board terminal.
2. Components on the main board
fall down leads short circuit.
3. Indoor evaporator temp. sensor
damaged.(Check temp. sensor
value chart for testing)
4. Main board damaged.
