Example:
Examples of basic data selection:
1. House with low temperature* radiator systems
Markaryd = Area 10 (5). Set the “Heating curve
selection” knob to 10 and the “Heating curve off-
set” knob to -2.
2. House with floor heating** installed in a
concrete floor structure
Markaryd = Area 10 (5). Set the “Heating curve
selection” knob to 5 and the “Heating curve offset”
knob to -1”.
3. House with floor heating** installed in a timber
floor structure
Markaryd = Area 10 (5). Set the “Heating curve
selection” knob to 8 (10-2=8) and the “Heating
curve offset” knob to -1”.
* A low temperature radiator systems refers to a
system where the flow temperature needs to be
55 °C on the coldest day.
** Floor heating can be dimensioned very differently.
Examples 2 and 3 above refer to a system where
the flow temperature needs to be approximately
35 - 40 °C resp 45 - 50 °C on the coldest day.
The values stated on the map apply for the “Heating
curve selection”.
The first value applies for low temperature * radiator
systems. “Heating curve offset” is set to -2.
The value in brackets refers to 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. In these cases the “Heating
curve offset” is set to -1.
The map values are usually a good starting point and
concern an approximate room temperature of 20°C.
The values can be adjusted later if necessary.
Basic values for the automatic heating control system
The lower values in the north of Sweden are due to
the lower design outdoor temperature.
