5.5 Data plate
Two data plates are attached to the product at the factory.
The data plate on the top of the unit (2) is always accessible
and contains the basic information for the chimney sweep.
The main data plate (1) with all of the information is attached
to the rear of the electronics box. Any information that is not
listed here can be found in separate sections.

Barcode with serial number
3rd to 6th digits = production date
(year/week)
7th to 16th digit = product article number
5.6 Serial number
The serial numbers are located on the underside of the front
panel and on the data plate.
5.7 Sitherm Pro™ technology
The intelligent combustion regulation is based on the adapt-
ive Siemens Sitherm Pro™ combustion optimisation.
5.8 Display of the energy consumption, energy
yields and efficiencies
Note
When replacing the PCB, the values recorded up
to that point are completely reset in the product
and system control.
The product, the system control and the app show approx-
imate values for energy consumption, energy yields and ef-
ficiencies, which are extrapolated based on calculation al-
gorithms.
The values that are displayed in the app may differ from the
other display options due to staggered transfer intervals.
The determined values depend on:
– Installation and system of the heating installation
– User behaviour
