Four-way valve reversal failure in your hydro-s Heat Pump can be caused by the valve failing to reverse or a lack of refrigerant. To troubleshoot, switch to cooling mode to check if the 4-way valve has reversed correctly, replace the 4-way valve if necessary, and add refrigerant.
What to do if my hydro-s Inverter 16 shows a low pressure failure?
A low pressure failure in your hydro-s Heat Pump could be due to a bad connection or failure of the low pressure switch, a blocked EEV or jammed pipe system, abnormal motor speed, or gas leakage. To address this, check the wiring for the low pressure switch, or replace it. Inspect the EEV and piping system, check the motor, and use a high pressure gauge to check the pressure value.
Why does my hydro-s Inverter 16 Heat Pump show input current over high protection?
An input current over high protection in your hydro-s Heat Pump can be triggered by a compressor current that is too large, abnormal water flow, power fluctuations, or an incorrect PFC inductor. To troubleshoot, check the compressor and the waterway system. Also, verify that the power supply is within the normal range and that the correct PFC inductor is being used.
How do I resolve exhaust temperature too high protection on my hydro-s Inverter 16 Heat Pump?
Exhaust temperature too high protection in your hydro-s Heat Pump can occur due to a lack of gas, low water flow, a blocked piping system, or a faulty exhaust temperature sensor. To resolve this, check the high pressure gauge and add gas if the pressure is too low. Inspect the waterway system and water pump, check the piping system for any blockages, and replace the exhaust temperature sensor if necessary.
What to do if there is an inter-chip communication failure on the main control board of my hydro-s Inverter 16 Heat Pump?
If there is an inter-chip communication failure on the main control board of your hydro-s Heat Pump, turn off the electricity supply and restart it. If the problem persists, replace the main board.
What causes inlet water temperature sensor failure in hydro-s Inverter 16?
Inlet water temperature sensor failure in your hydro-s Heat Pump can be caused by a sensor failure or short circuit, or loose sensor wiring. To resolve this, re-fix the wiring of the sensors or replace the sensor.
What should I do if my hydro-s Inverter 16 displays IPM module protection?
IPM module protection in your hydro-s Heat Pump can be triggered by data mistakes, wrong compressor phase connection, compressor liquid and oil accumulation, or damage to the compressor or driver board. To resolve this, turn off the electricity supply and restart after 3 minutes, replace the driver board, and check the compressor sequence connection.
What causes DC fan motor failure in hydro-s Inverter 16 Heat Pump?
DC fan motor failure in your hydro-s Heat Pump can be caused by a damaged DC motor, a damaged main board, or a stuck fan blade. To fix this, test the DC motor and replace it if necessary, replace the main board, and remove any obstruction that is preventing the fan blade from spinning freely.
How to fix communication failure between main board and driver board in hydro-s Inverter 16?
A communication failure between the Main board and driver board in your hydro-s Heat Pump can be caused by a poor connection or damage to the communication wire. To resolve this, check the wire connection and replace the wire if necessary.
Why is the temperature of the IPM module too high in my hydro-s Inverter 16 Heat Pump?
If the temperature of the IPM module is too high in your hydro-s Heat Pump, it could be due to an output exception of the IPM module thermal circuit, a motor issue, or a broken fan blade. To solve this, replace the driver board, check the fan motor speed or replace the fan motor if damaged, and replace the fan blade.
