Parameter
HP Version Setting the version of the HPSU compact
Function Heating Setting as to whether there is an additional heat generator (WEZ) for hot water
Rod generation and heating support.
0: No additional WEZ
1: Electric WEZ
2: Alternative WEZ takes over the hot water generation and heating support
3: Alternative WEZ 1 takes over hot water generation and alternative WEZ 2 takes
over heating support
HZU Heating support from hot water tank
0: no heating support
1: heating support activated
Bivalence Function The bivalence temperature is relevant for operation of the optional ancillary heater
based on a backup demand (room heating operation).
If the function is activated, the backup heater is only released if the temperature
falls below the bivalency temperature (adjustable in Configuration).
If the "Bivalency Temperature" function is deactivated, the operation of the backup
heater is always possible.
0: deactivated 1: activated
SMART GRID Activating the Smart Grid function
As soon as this function is activated, and depending on the signal emitted by the
energy supply company, the heat pump is switched off or operated more.
0: deactivated 1: activated
Mode SG Selecting the Smart Grid function
If the parameter "SMART GRID" is activated, it can be used to control the temper-
ature setback in economy mode (hot water generation and heating) and the flow
temperature increase at switch-on command.
0: Comfort (set value elevation of the hot water temperature by 5 K)
1: Standard (set value elevation of the flow temperature by 2 K and the hot water
temperature by 5 K)
2: Eco (set value elevation of the flow temperature by 5 K and the hot water tem-
perature by 10 K)
HT/NT Function This parameter sets which heat sources are switched off when the off-peak signal
is received from the energy supply company (EVU).
0: deactivated (no effect)
1: compressor switched off
2: compressor and reserve heating is switched off
3: everything is switched off (no unit function; Stand-By)
HT/NT Contact Determination whether it is a NC or NO contact.
0: evaluation of a NO contact
1: effect of a NC contact
Room thermostat Activating a room thermostat. When this function is activated the room set temper-
ature is only controlled by the room thermostat.
0: deactivated 1: activated
Interlinc fct Can only be used for systems with different set value probes (for example second
room thermostat). This parameter setting offers the opportunity of using 2 set val-
ues. As soon as this function is activated (e.g. when connecting an additional HP
convector) we operate according to 2 set values, depending on the demand. The
second set value corresponds to the normal set value +5 K (in cooling -5 K).
0: deactivated 1: activated
Outside Config Parameter for configuring the external temperature sensor. If this parameter is ac-
tivated and anexternal sensor is not connected, an error message is generated.
0: deactivated 1: activated
Storage Config This parameter can be used for setting the sensor for hot water generation. In the
setting 0: "inactive" no sensor is evaluated and the functionality of the hot water
generation is deactivated.
In the setting 1: "Sensor" a sensor is evaluated and the functionality of the hot wa-
ter generation is activated. In the setting 2: "Thermostat" a thermostatic switch (ON
/ OFF) is evaluated for hot water generation, and where "open brackets" are eval-
uated as "no demand". Functionality of hot water generation is activated.
0: inactive; 1: sensor; 2: thermostat
Konfig DFS Parameter for configuring the sensor for evaluation of the return temperature that
is evaluated by the temperature sensor in the flow sensor.
0: deactivated 1: activated
Pressure Config Parameter for configuring the sensor for evaluating the water pressure in the
system.
0: deactivated 1: activated
