Tuning the boiler
The appropriate heating curve is essential in order to have the 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 mean 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 "Shunt control" menu. In this menu it is
possible 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. If you do not know at all what temperatures your house
needs, you can use our recommended values:
- Houses with underfloor heating in concrete. "Slope 35"
- Well insulated low energy house with low temp. radiators. "Slope 40" (factory settings)
- A high temp. radiator system in a older house with poor insulation."Slope 55"
Example of curve:
If the slope is set to 50˚C this is the temperature sent to the flow at an outdoor
temperature of -15˚C.
If the house has underfloor heating the temperature on the curve is set significantly
lower.
Example of adjustment:
Adjustement of the curve means that you can raise or lower the indoor temperature
at a certain outdoor temperature. Curve adjustement 0 means that the flow is 20 °C
when the outdoor temperature is 20 °C. A curve adjustement of -5 means that the
temperature is 15°C.
