10. Adjust the heating curves
The heating curves represent the relationship between the outdoor temperature
and the boiler water or supply temperature. Put simply: The lower the outdoor
temperature, the higher the boiler water temperature. In turn, the room
temperature is dependent on the boiler water temperature.
The slope of the heating curve is
normally within the range marked
A
for underfloor heating systems
B
for modulating heating systems
C
for heating systems with boiler
water temperatures over 75°C.

1. Set the desired room temperature
Normal room temperature
Set the desired day temperature with
the set-point selector.
Desired room temperatures can
be set separately for each heating
circuit.
The value is automatically
accepted after approx. 2 seconds.
Reduced room temperature
Press
tm
to call up the desired night
temperature; adjust the desired night
temperature with the
or
button.
Press
to confirm the selected
