TIP
Wait 24 hours before making a new setting,
so that the room temperature has time to sta-
bilise.
If it is cold outdoors and the room temperature
is too low, increase the curve slope by one in-
crement.
If it is cold outdoors and the room temperature
is too high, lower the curve slope by one incre-
ment.
If it is warm outdoors and the room temperat-
ure is too low, increase the curve offset by one
increment.
If it is warm outdoors and the room temperat-
ure is too high, lower the curve offset by one
increment.
Basic values for the automatic heating control
The values stated on the map apply for the "heating
curve" in menu 1.9.1
The first value applies for low temperature* radiator
■
systems. "temperature" (offset heating curve) in menu
1.1 must be set to -2.
The value in brackets refers to under floor heating
■
systems** installed in concrete floor structures.
■ When the system is installed in a timber floor structure
you can use the number before the brackets, but this
value must be reduced by two units. "temperature"
(offset heating curve) in menu 1.1, set in these cases
to -1.
Caution
The map values are usually a good starting
point and are intended to provide an approx-
imate room temperature of 20 °C. The values
can be adjusted later if necessary.
Examples of basic values selection:
■ House with low temperature* radiator systems
London = Area 15 (8).
Set 15 in menu 1.9.1, "heating curve" and -2 in menu
1.1 "temperature" (offset of heating curve).
■ House with under floor heating** installed in a con-
crete floor structure
London = Area 15 (8).
Set 8 in menu 1.9.1, "heating curve" and -2 in menu
1.1 "temperature" (offset of heating curve).
■ Houses with under floor heating** installed in a timber
floor structure
London = Area 15 (8).
Set 13 (see point three in the list above) in menu 1.9.1,
"heating curve" and -1 in menu 1.1 "temperature"
(offset of heating curve).

Caution
An increase in the room temperature can be
slowed by the thermostats for the radiators or
under floor heating. Therefore, open the ther-
mostat valves fully, except in those rooms
where a cooler temperature is required, e.g.
bedrooms.
* A low-temperature radiator system refers to a system where the
supply temperature needs to be 55 °C on the coldest day.
** Under floor heating can be dimensioned very differently. The
example above refers to a system where the supply temperature
must be approx 35 – 40 °C resp. 45 – 50 °C on the coldest day.
