S1 is the flow sensor, S2 is the return sensor. If VFS has been selected as the flow
rate sensor, the return temperature is measured automatically via the VFS sensor.
In this case, the return sensor can be changed with the Sen. return parameter.
Depending on the flow rate sensor selected further adjustment channels appear,
see page 12.
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
Concentration is indicated in which the antifreeze ratio of the heat transfer fluid
can be adjusted.
For temperatures below 0 °C a heat transfer fluid with antifreeze is to be used.
The Metering channel is used for selecting whether heat quantity, cold quantity or
both are to be metered.
When the Alternative unit option is activated, the device will convert the en-
ergy quantities into the quantity of fossil fuels (coal, oil or gas) saved, or the CO
2
emission saved respectively. The alternative Unit can be selected. A factor must be
adjusted for the calculation. The conversion factor depends on the arrangement in
use and has to be determined individually.
In the S0 output menu, a digital impulse output can be adjusted for each calorim-
eter, in order to issue the energy metered in form of pulses. The impulse duration,
break and rate can be adjusted.
In order to reset the settings of a calorimeter, select Reset and confirm the secu-
rity enquiry with Yes.
With the menu item Function, a calorimeter already adjusted can be temporarily
deactivated or re-activated respectively. In this case, all adjustments will remain
stored. If a calorimeter is deactivated, energy metering does not take place by this
one. Sensor faults are ignored for the deactivated HQM.
