Please check the high pressure switch itself and the system pressure at first because HP1 means the system pressure is too high;
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℃.
You can solve the problem according to such points: 1) Check whether the filter is blocked; 2) Check whether the water flow rate is higher than the rated rate;
Please check the water inlet temperature sensor at first because E1 means this sensor is short or open; If necessary, please replace it with a new sensor.
Please get in touch with native distributors of Phnix.
One year for the whole heat pump, and two years for the major parts.
Please check the system pressure switch itself and the system pressure at first because LP1 means the system pressure is too low.
Please check the water outlet temperature sensor at first because E2 means this sensor is short or open; If necessary, please replace it with a new sensor.
