Depending on the installation and set-
tings, your heating system is either
room temperature-dependent or
weather-compensated in conjunction
with an outside temperature sensor.
■ In room temperature-dependent
mode, the set room temperature is
controlled via the flow temperature.
■ In weather-compensated mode
with room influence, the set room
temperature is controlled via the
selected heating curve and room
influence factor. The room influence
factor can be set by your local heat-
ing contractor.
■ In weather-compensated mode
without room influence, the room
temperature is controlled via thermo-
static valves. At the temperature lev-
els Comfort 1 to 3 and Party, the flow
temperature is controlled according
to the selected heating curve. In
reduced mode (setback mode and
eco mode), the flow temperature is
reduced by a parallel shift of the
heating curve. The setting of the
heating curve and the height of the
parallel shift can be changed by your
heating contractor.
Note
In weather-compensated mode with-
out room influence, choosing temper-
ature levels Comfort 1 to 3 or Party
does not result in different room tem-
peratures.
