the air volume required for the combustion of the
energy level located in the grate.
Here the ACTUAL flame temperature is compared
with the TARGET in combination with the processor-
regulated control unit and the appropriate combustion
air volume required for the combustion of the energy
level in the grate is supplied by means of the induced
draught fan.

Flue gas thermosensor
The flue gas thermosensor is located on the housing
of the induced draught fan and protrudes into the flue
gas duct across the direction of the flow of the flue
gas, where the flue gas flows around it, and thus
measures its temperature and temperature change.
(See Figure 10).
With the thermosensor, the temperature and its
change can be measured directly (accurate to about
2ºC) in the flue gas and so be accessed for the
control unit and regulation.

Room temperature sensor
The room temperature sensor measures the
ACTUAL room temperature in the area of the
stove.
The room temperature sensor is an instrument for
the TARGET
– ACTUAL comparison between the
TARGET room temperature and the ACTUAL room
temperature and is therefore the basis for the
specification of the required heat output for the
stove.
