B: Reference room temperature control
Used if your heating system is not equipped with radiator
thermostats and you select the room with room sensor as a
temperature reference for the rest of the rooms.
(However, should you have a few radiator thermostats
installed, make sure that they are fully open).
Set a positive value for the min. influence and a negative
value for the max. influence.
Influence
The room sensor in the reference room registers the
difference between the desired and the actual room
temperature. The desired flow temperature will be corrected
to eliminate this difference.
Example 1
The actual room temperature is 2 degrees too low.
The influence at max. limitation (right corner of the display) is
set to -35.
The influence at min. limitation (left corner of the display) is set
to 20.
Heat curve H is 1.8.
Result:
The desired flow temperature is changed by
2 x 20 x 1.8 x 0.1 = 7.2 degrees.
Example 2
The actual room temperature is 2 degrees too high.
The influence at max. limitation (right corner of the display) is
set to -35.
The influence at min. limitation (left corner of the display) is set
to 20.
Heat curve H is 1.8.
Result:
The desired flow temperature is changed by
2 x (-35) x 1.8 x 0.1 = -12.6 degrees.
