HEATING CURVE

Heating curve steepness indicates, what temperature is required for the heating bodies by a
determined outdoor temperature. The steepness value depends mainly on the heating sys-
tem type (floor, wall, radiator, convector heating) and insulation of the building.
Determining the heating curve steepness
If you have enough data, you can determine the heating curve steepness with a calculation,
otherwise from experience, based on the evaluation of heating system dimensioning
and building insulation.
The heating curve steepness is set correct, if the room temperature remains stable, even by
large outdoor temperature changes.
When the outdoor temperature remains above + 5 °C, you can adjust the room temperature
by changing the setting for day or night temperature or with the parallel shift of the heating
curve (parameters P2.2 and P3.2). If it gets colder in the building, while the outdoor tempera-
ture is dropping, then the heat curve steepness is set to low - you should increase the
setting. If the object by low outdoor temperatures gets warmer, the heat curve steepness
needs to be decreased.

Parameter description
Setting of running time for d. h. w. circulation pump. Pump running
period is always followed by the pump stand-by period.
Setting of stand-by time for d. h. w. circulation pump. Pump stand-
by period is always followed by the pump running period.
Parameter description
Setting of min. liquid fuel boiler temperature.

Parameter description
Setting of difference between solar collectors or solid fuel boiler
temperature and storage tank or heat accumulator temperature by
which the circulation pump shall switch-on.
Setting of difference between solar collectors or solid fuel boiler
temperature and storage tank or heat accumulator temperature by
which the circulation pump shall switch-off.
Setting of min. solar collector or solid fuel boiler temperature to
activate the circulation pump.
This setting enables compensation of the effect of heat passing
through the exterior walls of a heated building on the temperature
of the outdoor sensor.
