Malfunction
Error code
Reason
Solution
T2-TH5 water temp.
Too low protection
under cooling mode
PP11
1. Low water flow
2. Outlet water temperature
sensor d2-TH5 abnormal
3. The difference of outlet
water temperature and
set temperature is 7°C or
above in cooling mode
1. Check filtration pump and
waterway system
2. Change outlet water
temperature sensor d2-TH5
3. Change the set temperature.
High pressure failure
TS4
EE01
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
mode
5. Gas system jamed
6. High pressure wire is loose
or damaged
7. Too much refrigerant
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
Low pressure failure
TS5
EE02
1. EEV has blocked or pipe
system is jammed
2. Fan motor speed is
abnormal or fan motor is
damaged under heating
mode
3. Gas leakage
4. Low pressure wire is loose
or damaged
1. Check the EEV and piping
system Check the motor
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
Water flow failure
TS1
EE03 Or
„ON”
1. The wiring of water flow
switch is loose or water
flow switch damaged
2. No/Insufficient water flow.
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 jamed inside
Over heating
protection for water
temperature
(d2- TH5) in heating
mode
EE04
1. Low water flow
2. Water flow switch is stuck
and the water supply stops
3. TH5 outlet water
temperature sensor is
abnormal
4. The difference of outlet
water temperature and
set temperature is 7°C or
above in heating mode
1. Check the water flow switch if
it works well
2. Check the filtration pump or
the waterway system if there is
air or jammed inside
3. Check TH5 outlet water
temperature sensor or replace
a new one.
4. Change the set temperature.
