DHW PUMP_D sets whether or not the DHW pump is controlled by the M thermal Mono unit. If the DHW pump is to be

controlled by the M thermal Mono, select YES. If the DHW pump is not to be controlled by the M thermal Mono unit,

select NON.

DHW PUMP PRIORITY TIME SET set the operation time of DHW during DHW PRIORITY mode.

dT5_ON sets the temperature difference between the DHW set temperature (T5S) and the DHW tank water temperature

(T5) above which the heat pump providing heated water to the DHW tank. When T5S - T5 ≥ dT5_ON the heat pump

providing heated water to the DHW tank.

Note: When the heat pump’s leaving water temperature is

above the DHW mode leaving water temperature operating

limit (T5stop), the heat pump does not provide heated

water to the DHW tank. The DHW mode leaving water

temperature operating limit is related to ambient

temperature as shown in Figure 2-6.3 in Part 2, 6

“Operating Limits”.

dT1S5 sets the heat pump’s leaving water set temperature

(T1S) relative to DHW tank water temperature (T5). For DHW mode, the user sets the DHW set temperature (T5S) on the

main screen and cannot manually set T1S. T1S is set as T1S = T5 + dT1S5.

Figure 3-7.6 illustrates the operation of the heat pump and

immersion heater(optional) in DHW mode. If the DHW tank

water temperature (T5) is less than the minimum of the DHW

set temperature (T5S) and the heat pump leaving water

temperature operating limit (T5stop) (refer to Figure 2-6.3 in

Part 2, 6 “Operating Limits”) less dT5_ON, the heat pump

starts providing heated water to the DHW tank. After

t_TBH_delay minutes have elapsed, the immersion heater is

turned on. If T5 reaches T5stop, the heat pump stops but the

immersion heater continues running until T5 has reached T5S

+ dT5_TBH_OFF

T4DHWMAX sets the ambient temperature above which the heat

pump will not operate in DHW mode. The highest value that

T4DHWMAX can take is 43°C, which is the DHW mode upper ambient

temperature operating limit of the heat pump.

T4DHWMIN sets the ambient temperature below which the heat

pump will not operate in DHW mode. The lowest value that

T4DHWMIN can take is -25°C, which is the DHW mode lower ambient

temperature operating limit of the heat pump.
