Energy consumption correction factor
You can enter a correction factor to adjust the dis-
played (calculated) values for energy consumption/fuel
consumption to the actual values (as measured by the
meter in your home). The calculated value is multiplied
by the correction factor. However, due to seasonal cli-
mate conditions and other factors, discrepancies may
still arise.

Central heating and DHW heating energy consumption distribution
Specify the ratio in which your total energy consump-
tion (100 %) is to be split for central heating and DHW
heating. You can estimate the values or establish them
through repeated meter readings (gas meter or oil con-
sumption) over the year.
The values set here are only used in the graphs for
energy consumption ("Fuel consumption").
Factory setting:
■
DHW heating: 30 %
