Compressor phase current Compressor stops Check if the power cable to compressor is broken overload (over current) or short-circuited.
  • Page 93 Code Name Heat pump status Possible reasons and solutions Power plus offline Unit stops Communication between CPP controller and driver is OFF. Check if the wiring is loosened or not. Power plus generic AL Unit stops Check if the 3-phase power for outdoor unit is OK or not.
  • Page 94 Code Name Heat pump status Possible reasons and solutions High evap. temp. EVO Unit stops Bad ventilation condition for outdoor unit fans. Check if there is an obstacle at the fan system. Not enough water flow leads to low heat exchange in condenser.
  • Page 95 Code Name Heat pump status Possible reasons and solutions Amb. temp. probe fault (B1) Unit stops Sensor wiring is loosened, or sensor is defective. Check the wiring, if wiring is OK, check the sensors resistance. If resistance is not OK, replace the sensor.
  • Page 96 Code Name Heat pump status Possible reasons and solutions High press. swtich defect Unit stops Too much refrigerant. Reclaim and vacuum and inject the correct amount. There is air inside the refrigerant system. Vacuum again and inject new refrigerant. Not enough water flow leads to low heat exchange in condenser.
