Changing the slope:
A
The gradient of the heating curves changes.
Changing the level:
B
The heating curves are shifted in parallel in a verti-
cal direction.
Changing the standard room temperature (set
C
value):
The heating curves are offset along the "Set room
temperature" axis.
Note
Setting the slope or level too high or too low will not
result in damage to your heat pump or your heating
system.
Both settings have an effect on the level of the flow
temperature, which may then be either too low or
unnecessarily high.
Tips on when and how to change the heating curve
slope and level are displayed by pressing ?.

Heating/cooling circuits

A heating or cooling circuit is a sealed unvented circuit
between the heat pump and consumers (e.g. radia-
tors), in which the heating water or coolant circulates.
A separate cooling circuit is a sealed unvented circuit
that supplies a cooling appliance, such as a fan con-
vector or a chilled ceiling. Cooling via a separate cool-
ing circuit is independent of the outside temperature.
Heating and cooling of the entire interior can, if
required, be split over several heating circuits and one
cooling circuit.
Up to 3 heating circuits ("Heating circuit 1", "Heat-
ing circuit 2" or "Heating circuit 3") are possible. For
example, one heating circuit for the rooms occupied by
you and one heating circuit for the rooms of a separate
apartment.
