Installation & Owner‘s Manual
E-heater will be activated once for the current heating progress,
if want to apply E-heater again, plsease push .
For Model: HWHM-TDF190/1.5-H31 and HWHM-TDF300/3.5(E)-H31
Modes will be automatically selected by unit. manually mode
selection is unavailable.
Running Temperature 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(Maximum defrosting time depends
on model ).
Heat-up Time
There are different heat-up times in different ambient tempera-
ture. Normally lower ambient temperature result longer heat-up
time because of lower effective performance.
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.

NOTE
If only use E-heater, about only 3/5 tank water will be heated, so
must set higher target water temperature if ambient temperature
is out of heat pump running range.

If system occurs some malfunctions, error code and will

the unit will activate automatically E-heater as the backup heat
source, but the code and will be shown until power off.
About TCO and ATCO
The power of compressor and E-heater will be automatically
shut-off or turn on by TCO and ATCO.
If the temperature is higher than 78 , the ATCO will automati-
cally shut off the power of compressor and E-heater, and turn on
it if the temperature fall down below 68 .
If the water temperature is higher than 85 , the TCO will
automatically shut off the power of compressor and E-heater.
After that it needs to be reset manually.
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.
More detail please refer to Table.4-2, 4-3.

Operation mode should be selected manually. Refer to table 4-4.

NOTE
While the ambient temperature below than -7ºC(for model
TNF190 is 5ºC, heat pump efficiency will decrease dramatically,
the unit will automatically shift to E-heater running.
Restart After a Long Term Stop
When the unit is restarted after a long term stop(trail running
included), it is normal that outlet water is unclean. Keep the tap on
and the water will be clean soon.
