2. The wiring of sensor is loose
Ambient temperature or water inlet
PP07
temperature is too low
1. Out of the normal operating
ambient temperature for this machine
PP08
by checking d3
2. Sensor abnormality TH1
1. Ambient or the water temperature
is too high in cooling mode
PP10 2. Refrigeration system is abnormal
3. Pipe temperature sensor(TH2)
failure
1. Low water flow
2. Outlet water temperature sensor
TH5 abnormal
PP11
3. The difference of outlet water
temperature and set temperature is
7℃ or above in cooling mode
1. Ambient temperature is too high
2. Water temperature is too high
3. Water flow is too low
4. Fan motor speed is abnormal or
fan motor is damaged under cooling
EE01
mode
5. Gas system jammed
6. High pressure wire is loose or
damaged
7. Too much refrigerant
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. Check the ambient temperature
2. Check refrigeration system
3. Change the pipe temperature sensor
(TH2)
1. Check filtration pump and waterway
system
2. Change outlet water temperature sensor
TH5
3. Change the set temperature.
1. Choose the silent mode.
2. Check the water flow or filtration pump
3. Check the fan motor under cooling
mode, replace a new one if it is abnormal.
4. Check and repair the refrigerating
system
5. Reconnect the high pressure wire or
replace a new high pressure switch
6. Check and repair the refrigerating
system
