Adjustments of heating curves
▀
The appropriate heating curve is essential in order to have to right indoor temperature. The
heating curve needs to be adjusted to the specific energy demands of the house it is installed
in. All houses have different demands, which could give that one house would need a 25˚C flow
at a outdoor temperature of +-0˚C while another house needs 45˚C.
Adjustment to the heating curve is done in the menu "Shunt control". In this menu it is pos-
sible to alter both the slope and the adjustment to the curve. To find and adjust the correct
heating curve it is important that the following points are fulfilled:
- The outdoor temperature must not be higher than +5˚C
- Energy saver function must be switched off.
- Valves on the radiators must be fully open.
- Radiators must be checked and in function.
It is normal that during the first heating season changes must be done several times in order
to find the right setting for the house. When the right setting is found there is no need for any
changes for years to come. This is the greatness with an outdoor sensor. To start out with
something as a rule of thumb we could recommend these initial settings:
- Houses with underfloor heating in concrete. "Slope 35"
- Well insulated low energy house with low temp. radiators. "Slope 40"
- A high temp. radiator system in a older house with poor insulation. "slope 55"
Example of slope:
If the slope is set to 50˚C this is the temperature sent to the flow at a outdoor temperature of
-15˚C.
Example of adjustment:
When an adjustment is done to the slope this is done parallel to the curve. Meaning that if an
adjustment of 5˚C is done. This happens for the whole slope.
