There are two basic principles for control of the room
temperature inuence:
A: Max. room temperature limitation
Use this limitation if your system is fully equipped with
thermostats and you also want to obtain a max. limitation of
the room temperature. The controller will allow for free heat
gains, i.e. solar radiation or heat from a re place, etc.

limitation
The max. inuence determines how much the room
temperature should inuence the desired ow temperature.
Example
The actual room temperature is 2 degrees too high.
The inuence at max. limitation (right corner of the display) is
set to -40.
The inuence at min. limitation (left corner of the display) is set
to 0.
Heat curve H is 1.8.
Result:
The desired ow temperature is changed by
2 x -40 x 1.8 x 0.1 = -14.4 degrees.
