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 split into energy consumption for central
heating and energy consumption for DHW heating.
You can estimate the values or establish them through
repeated meter readings over the year.
The values set here are only used in the graphs for
energy consumption ("Fuel consumption").
Factory setting:
DHW heating: 65 %
■
■ Central heating: 35 %
