In the adjustment channel
Fluid type
, the heat
transfer fluid 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 fluid 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-
