dT5_ON is the temperature difference for starting the heat pump,

T5S is target temperature of domestic hot water. T5 is 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 ambient temperature that the heat
pump can operate for domestic water heating, the unit will not operate
if the ambient temperature is above it in DHW mode.
T4DHWMIN is the minimum ambient temperature that the heat
pump can operate for domestic water heating, the heat pump will
turn off if the ambient temperature drop below it in water heating mode.
The relationship between operation of the unit and ambient
temperature can be illustrated in the picture below:

T4DHWMIN
t_INTERVAL_DHW is the start time interval of compressor in DHW
mode. When the compressor stops running, the next time that the
compressor turn on should be " t_INTERVAL_DHW " minute later
at least.

dT5_TBH_OFF is the temperature difference between T5 and T5S
that turn the booster heater off, the booster heater will turn off if
T5≥T5S+dT_TBH_OFF, when the heat pump macfunction.
T4_TBH_ON is the temperature only when the ambient temperature
lower than it the booster heater will be available.
t_TBH_DELAY is the time that the compressor has run before
starting the booster heater(if T5＜min(T5S,T5stop)).
The operation of the unit during DHW mode described in the picture
below:
T5S+dT5_TBH_OFF

COMP.
In the picture, T5stop is a parameter relate to ambient temperature,
which can't be changed in the user interface, when T5≥T5stop, the
heat pump will turn off.

Note: the booster heater and backup heater can't operate
simultaneously, if the booster heater has been on, the backup
heater will be off.
If the booster heater is unavailable(1.2 TANK HEATER NON is
selected),the dT5_ON can't be adjusted and fixed at 2.

T5S_DI is the target temperature of water in the domestic hot water
tank in DISINFECT function.
