t_INTERVAL_DHW sets the DHW mode compressor re-start delay. When the compressor stops running, it will not re-start

until at least t_INTERVAL_DHW minutes have elapsed.

dT5_TBH_OFF sets the temperature difference between the DHW set temperature (T5S) and the DHW tank water

temperature (T5) below which the immersion is not used. When T5 ı Min(T5S+dT5_TBH_OFF, 65°C), the immersion

heater is off.

T4_TBH_ON sets the ambient temperature above which the immersion heater will not be used.

t_TBH_DELAY sets the delay between the compressor starting and the immersion heater being turned on.

T5S_DISINFECT sets the DHW tank disinfection operation target temperature. Caution: during the disinfection operation

(duration: t_DI_MAX) the domestic hot water temperature at the hot water taps will at times be equal to the value set for

T5S_DI.

t_DI_HIGHTEMP sets that length of time that the DHW tank disinfection operation

target temperature is maintained.

t_DI_MAX sets the total duration of the DHW tank disinfect operation.

t_DHWHP_RESTRICT sets the maximum length of time that the heat pump will

run in space heating or space cooling modes before switching to DHW mode, if a

requirement for DHW mode exists. When running in space heating mode or space

cooling mode, the heat pump becomes available for DHW mode either as soon as

the space heating/cooling set temperatures have been reached (refer to Part 3, 7.5 “COOL MODE SETTING Menu” and Part

3, 7.6 “HEAT MODE SETTING Menu”) or after t_DHWHP_MAX minutes have elapsed.

t_DHWHP_MAX sets the maximum length of time that the heat pump will run in DWH mode before switching to space

heating mode or space cooling mode if a requirement for space heating/cooling modes exists. When running in DHW

mode, the heat pump becomes available for space heating/cooling either as soon as the DHW tank water temperature (T5)

reaches the DHW set temperature (T5S) or after t_DHWHP_MAX minutes have elapsed.

Figure 3-7.9 illustrates the effects of t_DHWHP_MAX and t_DHWHP_RESTRICT when DHW PRIORITY is enabled. The heat

pump initially runs in DWH mode. After t_DHWHP_MAX minutes, T5 has not reached
