2. BASIC OPERATION PRINCIPLE
As we know with our experience, the natural flow
of heat, which moves from a higher to a lower
temperature source. the heat pump can transfer
heat from a lower temperature source to a higher
temperature source with high efficiency.
The advantage of a heat pump water heater is
that it can supply more heat energy, normally 3
times than input electricity power by extracting
the heat from ambient atmosphere in a free-of
charge way to Sanitary Hot Water, compare to the
traditional water heater, such as electric water
heater or gas burner water heater, their efficiency
is normally less than 1, which means it will
dramatically cut off the bill of family daily SHW by
the application of Heat pump water heater,
following data will show more details.

Technical Manual
11. Heat Source Shift
The default heating source is heat
pump.
If ambient is range out of heat pump,
heat pump will stop running, the unit
will shift automatically to activate E-
heater and show the icon LA on the
display, then if the ambient
temperature goes into the running
range of heat pump again, it will stop
E-heater and shift automatically to
heat pump again, and the icon LA will
be extinguished.
If the target setting water
temperature is higher than Max temp
(Heat pump), the unit will activate
heat pump firstly to the Max.
Temperature, then stop heat pump,
activate E-heater to continually heat
water to the target temperature.
If manually activate the E-heater
running mode when heat pump
running, E-heater and heat pump will
work together until the water
temperature gets to target
temperature. So if want to heat
quickly, please manually activate E-
heater.
NOTE: E-heater will be activated once for the
current heating progress, if want to apply E-heater
again, please push
If system occurs some malfunctions, error code
"E7" and will be shown on the display, then
heat pump will stop running, and the unit will
activate automatically E-heater as the backup
heat source, but the code "E7" and will be
shown until power off.
NOTE: If only use E-heater, about only 150 liters
water will be heated, so must set higher target
water temperature if ambient temperature is out
of heat pump running range.
Defrosting During Water-heating
In heat pump running period, if the evaporator
frosted in lower ambient temperature, the system
will defrost automatically to keep effective
performance(about 3~10min). At defrosting time,
the fan motor will stop, but compressor will still
run.
COP
There is different COP in different ambient
temperature.
Normally lower ambient temperature result
longer heat-up time because of lower effective
performance.
When ambient temp below 2℃, heat pump and
E-heater will take different portions of heating
capacity, generally the lower of ambient
temperature, the lower portion of heat pump will
be taken as well as the higher portion of E-heater
will account for.
About TCO and ATCO
The power of E-heater will be automatically shut-
off or turn on by TCO and ATCO.
If the temperature is higher than 78℃, the ATCO
will automatically shut off the power of E-heater,
and turn on it if the temperature falls down below
68℃.
