Outside Temp Adap This parameter is used for setting the individual adaptation of the measured value
relevant to the outside temperature.
NE -5 - 5 0 0.1
Terminaladress Parameter for setting the bus address for system access. N E 0 - 5 0 1
System Config The system configuration of the unit, consisting of the sensor configuration and bus
configuration, can be deleted, activated and deactivated with this parameter. If you
answer "Yes" to the enquiry about using the standard configuration when starting
the unit for the first time, the system configuration will be activated automatically.

System Configuration
BOH power Heating output of electric auxiliary heater for hot water generation N E 1000 -
40000 W
3000 W 1000 W
BUH s1 power Heat capacity of the ancillary electric heater in Stage 1 heating support N E 1000 -
40000 W
3000 W 1000 W
BUH s2 power Heat capacity of the ancillary electric heater in Stage 2 heating support N E 1000 -
40000 W
3000 W 1000 W
Power BIV Heat capacity of the alternative heat generator Serves to limit the heating support.
Output at which the heating support is operated until the temperature falls below
the temperature limit parameter [Overtemp CH Support].
N E 4000 -
40000 W
5000 W 1000 W
Overtemp CH Sup-
port
Over-temperature (above set hot water temperature) limit up to which the hot water
tank may be discharged by heating support.
NE 2 - 15 5 1
T vbh1 max Maximum flow temperature (checked by the integrated mixer valve).
Limits the heating support to the set temperature.
N E 5 - 60°C 60 °C 1 °C
T dhw activ As soon as the storage tank temperature exceeds and holds this value for a spec-
ified period, the heat pump goes to standby mode. Not under 8 °C outdoor temper-
ature.
N E 50 - 80°C 60 °C 1 °C
Bivalence Tempera-
ture
Outdoor temperature from which the optional ancillary heating is activated for sup-
porting the room heating. The bivalence temperature is relevant for operation of
the optional ancillary heater based on a backup demand (room heating operation).
We use the integrated temperature sensor on the external unit of the heat pump
(different from the one shown in the display).
E E -15 - 35°C 0 °C 1 °C
Quite Mode Mode for low-noise operation: Two modes are available. In certain cases, whisper
mode can become apparent through reduced performance.
0: deactivated
1: activated
2: Interval (at night between 22:00 and 5:00 operates in whisper mode)
EE 0 - 2 0 1
AUX fct Allocation of the switch conditions for the AUX contact.
0: Function deactivated
1: TDHW 1 Min
2: Operating mode
3: BUH
4: Error
5: TVBH1 save
6: BIV parallel
7: BIV alternative
8: BOH
NE 0 - 8 0 1
AUX time Delay (hysteresis) special function, after this time the AUX contact is switched. N E 0 - 600 s 120 s 5 s
T dhw1min Temperature-dependent switching threshold for AUX contact; see RPS3 (BSK) N E 20 - 85°C 50 °C 1 °C
PWM MAX Top limit for the modulation of the PWM signal. N E 0 - 100 50 1
PWM MIN Lower limit for the modulation of the PWM signal. N E 0 - 100 0 1
Spread CH Temperature spread modulation upper limit for heating mode N E 2 - 20 7 1
Spread DHW Temperature spread modulation upper limit for hot water heating mode N E 2 - 20 7 1
Time PD Decay delay in integrated circulation pump for minimization of relay play. N E 10 - 600 s 300 s 10 s
