t_INTERVAL_DHW sets the DHW mode compressor re-start delay. When the compressor stops running, it will not re-start unl at
least t_INTERVAL_DHW minutes have elapsed.
dT5_TBH_OFF sets the temperature dierence between the DHW set temperature (T5S) and the DHW tank water temperature
(T5) below which the immersion is not used. When T5 > Min(T5Stop+dT5_TBH_OFF, 65°C), the immersion heater is o.
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 starng and the immersion heater being turned on.
T5S_DI sets the DHW tank disinfecon operaon target temperature. Cauon: during the disinfecon operaon (duraon: t_DI_
MAX) the domesc hot water temperature at the hot water taps will at mes be equal to the value set for T5S_DI.
t_DI_HIGHTEMP sets that length of me that the DHW tank disinfecon operaon target temperature is maintained.
t_DI_MAX sets the total duraon of the DHW tank disinfect operaon.
t_DHWHP_RESTRICT sets the maximum length of me that the heat pump will
run in space heang or space cooling modes before switching to DHW mode, if a
requirement for DHW mode exists. When running in space heang mode or space
cooling mode, the heat pump becomes available for DHW mode either as soon as
the space heang/cooling set temperatures have been reached (refer to Part 3,
8.5 “COOL MODE SETTING Menu” and Part 3, 8.6 “HEAT MODE SETTING Menu”)
or aer t_DHWHP_MAX minutes have elapsed.
t_DHWHP_MAX sets the maximum length of me that the heat pump will run in DWH mode before switching to space heang
mode or space cooling mode if a requirement for space heang/cooling modes exists. When running in DHW mode, the heat
pump becomes available for space heang/cooling either as soon as the DHW tank water temperature (T5) reaches the DHW set
temperature (T5S) or aer t_DHWHP_MAX minutes have elapsed.
Figure 3-8.9 illustrates the eects of t_DHWHP_MAX and t_DHWHP_RESTRICT when DHW PRIORITY is enabled. The heat pump
inially runs in DWH mode. Aer t_DHWHP_MAX minutes, T5 has not reached
DHWPUMP TIME RUN sets whether or not the user is able to set the DHW pump (eld supply) in DHW mode. For installaons
with a DHW pump, select ON so that the user is able to set pump start mes.
