Displace (parallel displacement)
Setting range
-20 ... 20
Adjust the parallel displacement of the heat curve with a number of degrees, if required.
Whether it is reasonable to change the 'Slope' (at outdoor temperatures below 0 °C) or
parallel displacement (at outdoor temperatures above 0 °C) will depend on the individual
heat requirement.
Small increases or reductions in the heating temperature can be implemented by means of
the parallel displacement.
Temp. min. (flow temp. limit, min.)
Setting range
10 ... 150 °C
Choose the allowed min. flow temperature for your system. Adjust the factory setting, if
required.
Temp. max. (flow temp. limit, max.)
Setting range
10 ... 150 °C
Choose the allowed max. flow temperature for your system. Adjust the factory setting, if
required.
The setting for 'Temp. max.' has higher priority than 'Temp. min.'.

Room T limit (room temperature limitation)
This section is only relevant if you have installed a room temperature sensor or room
panel / remote control.
0
The controller adjusts the desired flow temperature to eliminate the difference between
the desired and the actual room temperature.
There are two basic principles for control of the room temperature.
A: Max. room temperature limitation
Use this limitation if your heating 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 fire place, etc.
Influence
The 'Gain - max.' determines how much the room temperature should influence the
desired flow temperature.
If the 'Gain' is too high and / or the 'Intgr. time' too low, there is a risk of unstable control.
Example A1
The actual room temperature is 2 degrees too high.
The 'Gain - max.' is set to -4.0.
The 'Gain - min.' is set to 0.0.
The 'Slope' is 1.8.
Result:
The desired flow temperature is changed by 2 x -4.0 x 1.8 = -14.4 degrees.
