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
–
Seasonal weather effects
–
Various tolerances of unit-internal components
The values can be read in the following time forms:
–
Today
–
Yesterday
–
Last month
–
Last year
–
Total
The recording of the values only includes the product in the
factory-delivered condition. Supplementary accessories,
even if they are installed on the product, as well as any other
components in the heating system and other external con-
sumers, are not part of the data recording.
Deviations between the determined values and the actual
values may be significant. The determined values are there-
fore not suitable for creating or comparing energy billing, for
example.
