Antifreeze protection in
Winter
PP07
Ambient temperature or water inlet
temperature is too low
Normal protection
Low ambient temperature
protection
PP08
1.Beyond the scope of using
environment
2. Sensor abnormality 1. Stop using, beyond the scope of
using
2.Change the sensor
Piping temperature
too high protection
under cooling mode PP10
1. Ambient temperature is too high or
the water temperature is too high in
cooling mode
2. Refrigeration system is abnormal
1. Check the scope of using
2. Check refrigeration system
T2 water temp. Too low
protection under
cooling mode
PP11
1. Low water flow
2. T2 temperature sensor abnormal
1. Check water pump and waterway
system
2. Change T2 temperature sensor
High pressure failure EE01
1. Ambient temperature is too high
2. Water temperature is too high
3. Water flow is too low
Fan motor speed is abnormal or fan motor has
damaged
1. Check the water flow or water
pump
2. Check the fan motor
3. Check and repair the piping
system
Low pressure failure EE02
1. EEV has blocked or pipe system is
jammed
2. Motor speed is abnormal or motor
has damaged
3. Gas leakage
1. Check the EEV and piping system
Check the motor
2. Through the high pressure gauge
to check the pressure value
Water flow failure
EE03
Or” ON
”
1. Water flow switch is damaged
2. No/ Insufficient water flow.
1. Change the water flow switch
2. Check the water pump or the waterway
system
Over heating protection
for water temperature (T2)
in heating mode
EE04
1. Low water flow
2. Water flow switch is stuck and the water
supply is cut off
3. T2 sensor is abnormal 1. Check the water way system
2. Check the water pump or water flow
switch
3. CheckT2 sensor or change another one
8. Troubleshooting
