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 > 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_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 (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

DHWPUMP TIME RUN sets whether or not the user is able to set the DHW pump (field supply) in DHW mode. For
installations with a DHW pump, select ON so that the user is able to set pump start times.
PUMP RUNNING TIME sets the length of time the pump runs for at each of the user-specified start times on the DHW

DHW PUMP DI RUN sets wether or not the DHW pump (field supply) operates during the disinfection mode.

In COOL MODE SETTING the following parameters should be set.
COOL MODE enables or disables cooling mode. For installations with space cooling terminals, select YES to enable cooling
mode. For installations without space cooling terminals, select NON to disable cooling mode.
t_T4_FRESH_C sets the refresh time of cooling model climate temperature curve.
T4CMAX sets the ambient temperature above which the heat pump will operate
in cooling mode with lowest compressor frequency. The highest value that
T4CMAX can take is 46°C, which is the cooling mode upper ambient
temperature operating limit of the heat pump. Refer to Figure 3-7.11.
T4CMIN sets the ambient temperature below which the heat pump will not
operate in cooling mode. The lowest value that T4CMIN can take is -5°C, which
is the cooling mode lower ambient temperature operating limit of the heat pump. Refer to Figure 3-7.11.
dT1SC sets the minimum temperature difference between the heat pump leaving
water temperature (T1) and the heat pump leaving water set temperature (T1S)
at which the heat pump provides chilled water to the space cooling terminals.
When T1 – T1S ≥ dT1SC the heat pump provides chilled water to the space
cooling terminals and when T1 ≤ T1S the heat pump does not provide chilled
water to the space cooling terminals.
dTSC sets the temperature difference between the actual room temperature (Ta)
and set room temperature (TS) above which the heat pump provides chilled
water to the space cooling terminals. When Ta – TS ≥ dTSC the heat pump
provides chilled water to the space cooling terminals and when Ta ≤ TS the heat
pump does not provide chilled water to the space cooling terminals. Refer to
Figure 3-7.13. dTSC is only applicable if YES is selected for ROOM TEMP in the TEMP. TYPE SETTING menu. Refer to Part 3,
7.8 “TEMP. TYPE SETTING Menu”.
t_INTERVAL_C sets the cooling mode compressor re-start delay. When the compressor stops running, it will not re-start
until at least t_INTERVAL_C minutes have elapsed.
