Depending on the system setting (mixing circle = “Dis-
charge“), the screen switches either to the menu “Heating
curves”….
…or directly to the menu “Heating curves heating circle:”
NOTICE
If the menu “Heating curves” appears, select the
menu eld “Heating circle”. The heating curves for
the heating circle can be programmed if no xed
temperature is set.

Return ow temperature of heating circle
Reference value for external temperature
3 Table line „Heating curve end point“
Symbol for “Heating curve end point”
45 °C Table eld “Heating curve end point”
Example value here: 45 °C
-20 °C Table eld “Reference value for external tem-
perature” (= program setting that cannot be
changed)
The example shows means that the hot water
return ow temperature is to be 45 °C at an
external temperature of -20 °C.
4 Table line “Parallel offset”
Symbol for “Parallel offset”
20 °C Table eld “Parallel offset”.
Example value here: 20 °C (neutral)
20 °C Table eld “Reference value for external tem-
perature”
20 The example shown indicates that the base
of the heating curve is to be 20 °C at an ex-
ternal temperature of 20 °C.
An increase in the temperature value in the
table eld “Parallel offset” to, for example,
22 °C causes a parallel offset of the heating
curve by 2 °C upwards, while a reduction to,
for example, 18 °C causes a parallel offset of
the heating curve by 2 °C downwards.
5 Table line “Night reduction”
Symbol for night mode: Heating is lowered
-5 °C Table eld “Difference temperature”
The example shown indicates that the heating
in night mode is lowered by 5 °C in compari-
son to day mode.

Select table “Heating curve end point”…
NOTICE
The heating curve end point always refers to an ex-
ternal temperature of -20 °C. If the heat pump is
used in a climatic zone in which the external tem-
perature value of -20 °C is not reached, you need
to equalise the heating curve end point with the re-
gional standard design temperature.

point with the regional standard design tempera-

Set the return ow temperature value in the table eld
“Heating curve end point”…
NOTICE
The temperature values refer to the return ow.
You need to subtract the spread for ow tempera-
tures.
