Cooling ( Only applicable if the assigned heat generator has a cooling function.)
Start T-Out Cooling Only if [HC Function] parameter = 0:
Setting as of which outside temperature cooling mode starts with the highest target cool-
ing feed temperature [T-Flow Cooling start] (setting condition: "Cooling" operating
mode).
E E 15 - 45 °C 24 °C 1 °C
Max T-Out Cooling Only if [HC Function] parameter = 0:
Setting of the outside temperature at which the lowest target cooling feed temperature
[T-Flow Cooling max] is specified (setting condition: "Cooling" operating mode).
E E 20 - 45 °C 35 °C 1 °C
T-Flow Cooling start Only if [HC Function] parameter = 0:
Setting of the target cooling feed temperature at the start of cooling mode (outside tem-
perature = parameter [Start T-Out Cooling])
E E 5 - 25 °C 18 °C 1 °C
T-Flow Cooling max Only if [HC Function] parameter = 0:
Setting of the minimum target cooling feed temperature. This is held constant as of the
outside temperature ([Max T-Out Cooling] parameter).
E E 5 - 25 °C 8 °C 1 °C
Min T-Flow Cooling Only if [HC Function] parameter = 0:
Setting of the absolute lower limit of the target cooling feed temperature. Limitation acts
if a lower target cooling feed temperature is determined from other parameter settings.
N E 5 - 25 °C 18 °C 1 °C
T-Flow Cooling Only if [HC Function] parameter = 1:
Setting of the target cooling feed temperature (fixed value) for active cooling mode.
E E 8 - 30 °C 18 °C 1 °C
T_H/C Switch Automatic activation of cooling mode.
Off: Deactivated
10 - 40: if the outside temperature exceeds the set value, the system is switched to "Cool-
ing" operating mode. If the outside temperature falls 2 K below the set value, the system
automatically switches back to the previously activated operating mode.
N E Off, 10 - 40 °C Off 1 °C
Cooling Setpoint adj Parallel shift of the cooling characteristic curve by the set value. E E -5.0 to +5.0 kW 0.0 K 1 K

Circl-Pump DHW Setting for the control of a circulation pump.
Off: Optional circulation pump is controlled according to the [Circulation Time] switching time
program.
On: Optional circulation pump is synchronously controlled to the active switching time program
for hot water generation.
E E Off

Circl-Pump Interval Setting of the interval control for an optional circulation pump.
Off: Deactivated. The circulation pump runs permanently during the release times of the as-
signed switching time program ([Circl-Pump DHW] parameter).
Otherwise: The circulation pump runs clocked (clock cycle ratio: pump runtime = setting value
each 15
min).
E E Off,

Anti-Legionella time Setting of the start time for thermal disinfection of the hot water storage tank (format hh:mm). N E 00:00 - 23:45 03:30 15 min
Anti-Legionella temp Setting of the hot water target temperature during thermal disinfection of the hot water storage
tank.
N E 60 - 70 °C 65 °C 1 °C
Max DHW loading
time
Setting limits the period of time for hot water generation to the set target value [T-DHW Set-
point]. After the period of time has elapsed, the control unit switches back to the previously ac-
tive operating mode. Hot water generation is carried out to the then current target value.
N E 0 - 240 min 60 min 10 min
DHW Off Time Setting of the blocking time after completion or cancellation of a hot water generation cycle.
The repeat request for hot water generation is operated after this blocking time has elapsed at
the earliest.
N E 0 - 180 min 30 min 10 min

Hyst HP Hot water charging switching threshold
Setting of the temperature difference by which the temperature in the hot water storage tank
may fall in comparison with the currently valid target hot water temperature [T-DHW Setpoint]
before the heat pump for hot water charging is to be activated.
E E 2 - 20 K 7 K 1 K
