1.1 General information
Device group Systems
Product name optosonic u 3 radio net
Illustration
Design/type Radio module for ultego III
Functional description
The radio module optosonic u 3 radio net serves in in-
tegrating the heat meter ultego III into the radio system
symphonic sensor net.
For this, the opto head of the optosonic u 3 radio net is
connected to the optical interface of the ultego III. The
optosonic u 3 radio net reads out the measured values
of the ultego III via the interface. The data is saved in
the module.
The optosonic u 3 radio net is programmed via radio.
During the set-up, the optosonic u 3 radio net automat-
ically detects whether it is connected to a heat, cold or
combined heat/coldmeter.

Error status
Error status calculation
If several errors occur at once, the decimal error statuses are added. The result is unique values for
each error combination.
Example:
Error status 17 = 16 + 1:
▪16: Battery weak, non-critical
▪1: Dismantling detection
Consequence: Exchange device (due to the error status 1 as partial error).
