T5S_DISINFECT sets target water temperature of water tank of disinfect function.
T5S_DI 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 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/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.
Diagram below 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
