5-4 The defaults messages and what to do:

Failure code:
E1: sensor for T1(water temperature) failure
E2: sensor for T2(ambient temperature) failure
E3: sensor for T3(exhaust temperature from compressor) failure
E4: sensor for T4(coil temperature in condenser) failure
E5: Compressor stops three times in 24 hours because the current is too high.
E6: While heating water, there is three times of
E7: There is electric leakage in Compress or outdoor motor, four way valve.
Recommendation:

6 - Instructions of maintenance:

This operation must be done by a professional, qualified person, each year.
Clean the back evaporator with a delicate brush and a water jet without any pressure (karcher prohibited).
Check the instructions and working points of the apparatus
Check the safety measures
Check the pressure of the refrigerating gas

7 - The three electric heaters:

1.Condenser electric heater *
Working conditions: During the compressor running:
A .the heater start in defrosting period, to Speed up defrosting, to reduce defrosting time ;
B .When ambient temperature is less than 2℃, the heater start, and it stop when ambient temperature is more than 4℃.
2. Compressor electric heater *
Working conditions:
A When the compressor is not working and ambient temperature is less than 0℃， electric heater will start ;
B When ambient temperature is more than 2℃or compressor is working, electric heater will stop.
3. Water tank electrical heater (only for heat pump with assistant electrical heater)
The electrical heater of water tank has two mode: manual or automatic
(1) Automatic: precondition is under compressor running: if the water temperature does not up 1℃
remain or down in a certain time (the certain time is adjustable from 1 to 10 minutes, windows default is 3 minutes),
then the heater will start, until reach the setting temperature. The heater can not be stop forcedly when the electric
heater in the automatic mode. The heater will be start forcedly during defrosting.
(2) Manual: press the button
Or press again to stop the heater forcedly.
HEATER
If the water temperature has already reached the setting temperature, then it wills no effect to press the button.
Also the heater will restore to automatic state after the water temperature reach its desire.
when reach the setting temperature, the heater close and the light off.
The machine would give an alarm if the water tank's sensor finds water temperature is 2℃ or less,
User need to drain all inside water out to prevent unit damage from ice, also do it if machine not be
used a long time in winter .
Call your fitter to check or change the controller of flow.
once to start the heater forcedly, until reach the setting temperature it closes.
