BASIC VALUES FOR THEAUTOMATIC HEATING
CONTROL
The values stated on the map apply to "Curve, heating" in
menu 1.30.1.
• The first value applies to low temperature radiator sys-
tems
1
. " Temperature" in menu 1.1 must be set to -2.
• The value in brackets refers to underfloor heating sys-
tems
2
installed in concrete floor structures.
• When the system is installed in a timber floor structure,
you can use the number before the brackets, although
this value must be reduced by two units. "Temperature"
in menu 1.1 is set to -1 in these cases.
Caution
The map’s values are usually a good starting point
and are intended to produce a room temperature
of approximately 20 °C. The values can be adjusted
later, if necessary.
Examples of basic values selection:
• House with low temperature radiator system
London = Area 15 (8).
Set 15 in menu 1.30.1, "Curve, heating" and -2 in menu 1.1
" Temperature".
• House with underfloor heating installed in a concrete floor
structure
London = Area 15 (8).
Set 8 in menu 1.30.1, "Curve, heating" and -2 in menu 1.1
" Temperature".
• House with underfloor heating installed in a timber floor
structure
London = Area 15 (8).
Set 13 (see third item in the list above) in menu 1.30.1,
"Curve, heating" and -1 in menu 1.1 " Temperature".
Caution
An increase in the room temperature can be
slowed by the thermostats for the radiators or
under floor heating. Therefore, open the thermo-
stat 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.
2
Underfloor heating may be dimensioned very differently. The above example refers to a system where the supply temperature needs
to be approximately 35 – 40 °C or 45 – 50 °C on the coldest day.
