dT5_ON is the temperature difference for starting the heat pump, the picture below illustrates the dT5_ON function.
T5S is the target temperature for domestic hot water. T5 is
the actual temperature of domestic hot water. When T5 drops
to a certain temperature (T5
≤
T5S-dT5_ON) the heat pump
will be available. dT1S5 is the correct value for the target
outlet water temperature (T1S=T5+dT1S5).
T4DHWMAX is the maximum outdoor air temperature that
the heat pump can operate at for domestic water heating.
The unit will not operate if the outdoor air temperature goes
above it in DHW mode.
DHW mode setting
DHW:domestic hot water
DHW MODE SETTING typically consists of the following:
1.
DHW MODE: enable or disable the DHW mode
2.
TANK HEATER: set whether the booster heater is available or not
3.
DISINFECT: set the parameters for disinfection
4.
DHW PRIORITY: set the priority between domestic hot water heating and space operation
5.
DHW PUMP: set the parameters for DHW pump operation. The functions above apply only to installations with a domestic hot
water tank.
How to set the DHW mode
To determine whether the DHW mode is effective.
Go to MENU> FOR SERVICEMAN> DHW MODE SETTING. Press OK. The following page is displayed:

T4DHWMIN is the minimum outdoor air temperature that the heat pump can operate for domestic water heating. The heat pump
will turn off if the outdoor air temperature drops below it in water heating mode. The relationship between operation of the unit and
outdoor air
temperature can be illustrated in the picture below:

If DHW MODE is set "NON", the function is not available and so could not be selected by the user.
NOTE
T_INTERVAL_DHW is the start time interval of the compressor in DHW mode. When the compressor stops running, the next time
the compressor turns on it should be T_INTERVAL_DHW plus one minute later at least.
