In the adjustment channel Fluid type, the heat
transfer uid must be selected. If either Propylene
glycol or Ethylene glycol is selected, the adjustment
channel Ratio is indicated in which the antifreeze ra-
tio of the heat transfer uid can be adjusted.
When the Alternative unit is activated, the control-
ler will convert the heat quantity into the quantity of
fossil fuels (coal, oil or gas) saved, or the CO
2
emis-
sion 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
individually.
Heat quantity measurements already activated will
appear in the HQM menu above the menu item New
HQM in numerical order.
If an activated heat quantity measurement is selec-
ted, 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 disap-
pear 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.
