When parameter P27= 0, E2 is AC heating control port, When parameter P27 = 1, E2 is 2
nd
heat source control port
d) DHW Auxiliary Electric Heater E1
When parameter P27 = ―1‖, When E2 not start, E1 will work as normal DHW assistant
heater. When E2 start, E1 will be off.
When P27=‖0‖, the auxiliary electric heater
E1 turns on as set out in the conditions below:

Ambient temperature ≤ set value (parameter P09,-20
℃
~ 30
℃
, default 0
℃
);

Compressor’s working time ≥ 15 minutes;

DHW water tank temperature
＜
setting temperature;
When start defrost mode at DHW mode, E1 will be on if DHW temp<38c. when DHW
temp>42c, E1 off.
When DHW antifreeze, E1 is on, when DH>15C, E1 off.
When some error cause compressor stop, if DHW required, E1 will be on.
e) Multifunctional port E2
When parameter P27= “1”, E2 is for 2
nd
heat source control
A, if Ambient temperature
＜
set value (parameter P28),
E2 On, heat pump standby.
B, if Ambient temperature ≥ set value (parameter P28, default -15
℃
),
E2 Off, heat pump start working.
When P27=‖0‖
E2 is for AC auxiliary electric heater.
E2 turns on as set out in the conditions below:

When the heat pump is running AC heating or DHW but some error happen to stop
compressor, the auxiliary electric heater E2 will start together with E1.

When the heat pump is running AC heating:
A, When the heat pump runs AC heating normally, the auxiliary electric heater E2 turns on as
set out in the conditions below:

Ambient temperature ≤ set value (parameter P10);

Compressor’s working time ≥ 15minutes;

AC water inlet temperature +3C
＜
target inlet water temperature;
B, When start defrost at AC heating mode, if inlet water temperature ≤25
℃
, E2 turns on.
When Ac inlet temp>30c, E2 off.
C, During AC antifreezing, the auxiliary electric heater E2 turns on.
D, If inlet or outlet temperature sensor breakdown, the auxiliary electric heater E2 turns on.
f) Motorized 3 way Valve G2
In DHW mode, the motorized 3 way valve is power on. In any other mode, it is power off.
4.2: .Operating Mode Principle
1) Space Cooling Mode
Temperature setting range is 10-25 ° C, the factory setting is 12
℃
;
2) Space Heating Mode
Temperature setting range is 10-55 ° C, the factory setting is 45
℃
;
3) Hot Water Mode
Temperature setting range is 10-60 ° C(50~60c is increased by electric heater), the factory setting
is 50
℃
;
4) Defrost Cycle
Auto Defrost mode (normal defrosting)
All heat pumps are fitted with intelligent defrost controls. A number of parameters are taken into
account before defrost begins and ends. The parameters should be set as per factory settings or
