Parameter Description
Barometric
pressure
The input of the barometric pressure and
the height above sea level is only
required when no absolute pressure is
available (no CO
2
IR module present).
The barometric pressure influences the
calculation of flow speed, volume flow, mass flow
and flue gas dew point. To achieve a higher
accuracy, the values can be adjusted to the
actual ambient conditions.
This is 1013mbar (14.6 psi) as an annual
average, regardless of the altitude. Depending on
the current weather, this pressure can fluctuate
by ±20mbar (8 "H
2
O) around the annual average.
Altitude The height above sea level influences the
calculation of flow speed, volume flow, mass flow
and flue gas dew point. To achieve a higher
accuracy, the value can be adjusted to the actual
ambient conditions.
Dewpoint The parameter "Dewpoint" (combustion air
dewpoint) influences the calculation of qA (flue
gas loss) and flue gas dew point. The factory
setting for the dewpoint is 34.7 °F. To achieve a
higher accuracy, the values can be adjusted to
the actual ambient conditions.
