The values stated on the map apply for the Curve
slope.
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.
Examples of basic data selection:
1. House with low temperature* radiator system
Markaryd = Area 10 (5). Select curve 10 on the
display and -2 on the Increase/reduce heat knob.
2. House with floor heating** installed in
a concrete floor structure
Markaryd = Area 10 (5). Select curve 5 on the dis-
play and -1 on the Increase/reduce heat knob”.
3. House with floor heating** installed in a timber
floor structure
Markaryd = Area 10 (5). Select curve 8 (10-2=8)
on the display and -1 on the Increase/reduce heat
knob.
* A low temperature radiator system refers to a sys-
tem 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.
Basic values for the automatic heating control system
The lower values in the
north of Sweden are due
to the lower design out-
door temperature.
