cooling or rated heating
Displayed during the test of maximum
cooling or maximum heating
Displayed during the test of
intermediate cooling or intermediate
heating
1. Voltage between L and N on the
terminal differs from 210 to 250
VAC;
2. Compressor wiring loose or sliced ;
3. Compressor damaged;
4. Overabundance or insufficent
refrigerant;
5. Poor heat exchange (exchanger
dirty or poor air circulation).
1. Voltage between L and N on the
terminal differs from 210 to 250 VAC
2. Wiring loose or sliced (the unit
must be powered off for at least
20 minutes before checking the
wiring);
3. Capacitor damaged;
4. Electronic board damaged.
Electronic board damaged.
1. Check the thermal insulation of IPM
module and the radiator (the unit
must be powered off for at least
20 min);
2. Electronic board outdoor unit
damaged.
1. Ambient temperature is too high;
2. Poor heat exchange (exchanger
dirty or poor air circulation).
1. Ionizer wiring loose or sliced ;
2. Ionizer damaged;
3. Electronic board damaged.
1. Wiring the compressor loose or
sliced (under normal conditions the
resistance to this terminal should
be less than 1 ohm);
2. Overabundance or insufficent
refrigerant.
3. Obstruction refrigerant circuit;
4. Malfunction of compressor.
1. Condensing temperature is too
high;
2. Ambient temperature too high
3. Poor heat exchange (exchanger
dirty or poor air circulation).
