Operaon in DHW PRIORITY
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 starng and the immersion heater being turned on.
T5S_DI sets the DHW tank disinfecon operaon target temperature. Cauon: during the disinfecon operaon (duraon: t_DI_
MAX) the domesc 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 disinfecon operaon
target temperature is maintained.
t_DI_MAX sets the total duraon of the DHW tank disinfect operaon.
t_DHWHP_RESTRICT sets the maximum length of me that the heat pump will
run in space heang or space cooling modes before switching to DHW mode, if
a requirement for DHW mode exists. When running in space heang mode or
space cooling mode, the heat pump becomes available for DHW mode either as
soon as the space heang/cooling set temperatures have been reached or aer
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 heang
mode or space cooling mode if a requirement for space heang/cooling modes exists. When running in DHW mode, the heat
pump becomes available for space heang/cooling either as soon as the DHW tank water temperature (T5) reaches the DHW set
temperature (T5S) or aer t_DHWHP_MAX minutes have elapsed.
Figure below illustrates the eects of t_DHWHP_MAX and t_DHWHP_RESTRICT when DHW PRIORITY is enabled. The heat pump
inially runs in DWH mode. Aer 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 installaons
with a DHW pump, select ON so that the user is able to set pump start mes.
PUMP RUNNING TIME sets the length of me the pump runs for at each of the user-specied start mes on the DHW PUMP tab
on the DOMESTIC HOT WATER (DHW) menu, if TIMER RUNNING is enabled.
DHW PUMP DI RUN sets wether or not the DHW pump (eld supply) operates during the disinfecon mode.
