Please check the compressor discharge temperature at first because tC1 means the compressor discharge temperature is too high.
A heat pump is unlikely to heat your whole house. Heat pumps are like powerful, very efficient fan heaters. A typical heat pump provides the same amount of heat...
1) Please adjust the defrosting exit parameter D04 from 13 to 18 and the defrosting start parameter D03 from -7 to -3; also please check whether the setpoint is "0" for both D15 and D14.
Installation is critical. Sizing and positioning and installation are very important to good operation. The units require connecting piping to be added plus professional wiring during installation...
Because moisture or condensation can be a by-product of the PHNIX hot water heat pump depending on humidity and the run time of the heat pump. Condensate amount will vary according to these conditions.
The PHNIX hot water heat pump will not work without electrical power. When power is restored after an outage, the water heater will go through the dry fire process then automatically revert back to the original user setting.
1) Fan motor noise (blockage or the fan capacitor is aging); 2) Fan motor electromagnet noise (change a new one);
Operating a PHNIX hot water heat pump instead of a standard electric model could help a household avoid up to 62% of CO2 emissions on the grid from water heating.
The range of ambient running temperature of the unit?among -7℃-43℃.
