When room temperature compensation is
set, the heating circuit switches off if the
room temperature rises above the target
room temperature by the value set here.

When room temperature compensation
is set, cooling is enabled if the room
temperature rises above the target room
temperature by the value set here.

- room too cold
When room temperature compensation
is set, cooling switches off if the room
temperature falls below the target room
cooling temperature minus the value set
here.

cooling is enabled.

Room temperature compensation
With this type of control, the target flow temperature is
influenced by the room temperature. A room temperature
that is too high results in a reduction of the target flow
temperature. A room temperature that is too low results in
an increase in the target flow temperature.
The prerequisite for room temperature compensation is a
valid room temperature, measured by a room temperature
sensor.
If the set heating curve and the room temperature compen-
sation result in a target flow temperature that is lower than
the room temperature, then the target flow temperature
is limited to the current room temperature. Therefore no
more energy is emitted to the room. The room cools down.
Parameters Description
Room tem-
perature
compensation
correction fac-
tor Kp
This parameter enables the same type of room
temperature compensation as a P controller.
Different guideline values are recommended for
different heating systems. The actual setting must
be made and tested individually.
Setting range
0 - 10
Underfloor heating 0 - 2
Radiator heating 0 - 5
