or Ethylene glycol is selected, the adjustment channel
Ratio is indicated in which the antifreeze ratio of the
heat transfer fluid can be adjusted.
When the Alternative unit is activated, the cont-
roller will convert the heat quantity into the quan-
tity of fossil fuels (coal, oil or gas) saved, or the CO
2
emission saved respectively. The alternative Unit can
be selected. A conversion Factor must be adjusted
for the calculation. The conversion factor depends on
the arrangement in use and has to be determined in-
dividually.
Heat quantity measurements already activated will ap-
pear in the HQM menu above the menu item New
HQM in numerical order.
If an activated heat quantity measurement is selected,
the above mentioned menu with all adjustment values
will re-open.
To deactivate a heat quantity measurement, select the
menu item Delete function at the bottom of the
menu.
The heat quantity measurement deleted will disappear
from the list and become available for selection in the
New HQM menu again. The numeration of the other
activated heat quantity measurements will not change.
