B: Reference room temperature control
Used if your system is not equipped with thermostats and
you select the room with room temperature sensor as a
temperature reference for the rest of the rooms.
Set a positive value for the min. inuence and a negative
value for the max. inuence.
The room temperature sensor in the reference room registers
the dierence between the desired and the actual room
temperature. The desired ow temperature will be corrected
to eliminate this dierence.
Example 1
The actual room temperature is 2 degrees too low.
The inuence at max. limitation (right corner of the display) is
set to -35.
The inuence at min. limitation (left corner of the display) is set
to 20.
Heat curve H is 1.8.
Result:
The desired ow 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 inuence at max. limitation (right corner of the display) is
set to -35.
The inuence at min. limitation (left corner of the display) is set
to 20.
Heat curve H is 1.8.
Result:
The desired ow temperature is changed by
2 x (-35) x 1.8 x 0.1 = -12.6 degrees.
