available accessories) may occur between the measured room
temperature in the inhabited area and the desired room
temperature.

Heating curve setting (heating curve)

Press and hold the input button for 3 seconds to access the

"Heating Curve" menu.
The slope of the heating curve describes the relation between the
change in the flow temperature and the change in the outside
temperature. With a larger heating surface, such as with floor
heaters, the heating curve has a less extreme slope than with a
smaller heating surface (e.g. radiators).
The set value refers to the lowest outside temperature used for
heat demand calculation.
This parameter is to be set by the technician and should not be
altered anymore.
The setting of the heating curve should be carried out only in
small steps and at adequately long intervals so that a stable
condition can be set. We recommended making any corrections in
0.1 – 0.2 steps after 1 – 2 days.
