This parameter determines to what extent a deviation of the
room temperature from the specified setvalue has an influence
on the control of the heat generator temperature.
If there is no difference between desired (SET) and actual (ACT)
room temperature, the flow temperature of the heating circuit is
controlled in accordance with the adjusted heating curve.
Should the room temperature deviate from the adjusted setvalue,
the heating characteristic is adjusted on the room temperature
axis in such a way, that the control deviation is compensated. The
size of this displacement thereby depends on the setting of the
room effect.
The following relation applies:
with
Room setcorr = corrected new room setvalue
Room setnom = adjusted room setvalue
Room setcorr = Room setnom -
(
Deviation x Room factor
)

Example:
adjusted room setvalue = 21 °C
actual room temperature = 20 °C
The deviation resulting from this is therefore — 1 K.
The following applies with room factor 100 %:
Room setcorr = 21 °C -
(
-1K x 100
)
= 22 °C

The heat generator temperature is controlled in accordance with
a heating characteristic, which complies with a specified room
temperature of 22 °C.
Setting OFF: completely dependent on the weather
conditions without correcting the room set value
Setting RC: completely dependent on the room temperature
without any influence of the outside temperature
Important note: High settings reduce the stability of the control
circuit and may lead to fluctuations in room tem-
perature. The setting should be adapted to the
conditions of the room.
