Solution
1. Check or change the sensor
2.Re-fix the wiring of the sensors
1. Check or change the sensor
2.Re-fix the wiring of the sensors
1. Check or change the sensor
2.Re-fix the wiring of the sensors
1. Check or change the sensor
2.Re-fix the wiring of the sensors
1. Check or change the sensor
2.Re-fix the wiring of the sensors
1. Check the d1((inlet water temp.) and
d3(outlet water temp.)
2. Normal protection
1. Stop using, beyond the scope of using
2.Change the sensor
1. Choose the silent mode.
2. Check the water flow or filtration pump
3. Check and repair the refrigerating
system
4. Reconnect the high pressure wire or
replace a new high pressure switch
5. Check and repair the refrigerating
system
Solution
1.Check the EEV and piping system
2. Check the fan motor under heating
mode, replace a new one if it is abnormal
3. Check refrigeration system or check the
pressure value through the high-pressure
gauge.
4. Reconnect the low pressure wire or
replace a new low pressure switch
1. Check the wiring of water flow switch
or change a new one
2. Check the filtration pump or the
waterway system if there is air or jammed
inside
3.Check the flow switch position according
to the water flow direction.
