How to determine another heat curve, if necessary:
Choose the calculated flow temperature for your system and
the determined min. outdoor temperature for your area.
Pick the heat curve closest to the crossing point of these two
values.
The setting of the desired room temperature has an influence
on the calculated flow temperature (heat curve), no matter if
a room temperature sensor is connected or not.
Floor heating systems
This controller is factory set for radiator systems, which typically
are high flow temperature systems.
To control floor heating systems, which typically are low flow
temperature systems, you need to change the heat curve
according to your type of system.
