quantity into the quantity of fossil fuels (coal, oil or gas) saved, or the CO

emission
saved respectively. The alternative Unit can be selected. A Conversion factor
must be adjusted for the calculation. The conversion factor depends on the ar-
rangement in use and has to be determined individually.
Note:
In 2-store systems, the heat quantity of both stores can be measured with
one fl owmeter.
Heat quantity measurements already activated will appear in the HQM menu above
the menu item new HQM… in numerical order.
