By pressing the push-button briefly you can scan all the
information within a loop.
After 1 minute of non-use of the push-button, the display
automatically returns to the main loop.
1. Level / Main Loop
1) Total heat energy in MWh
– standard display- alternating display
without pressing at negative flow.
2) Segment test, all segments triggered simultaneously.
3) Heat energy at last billing date alternating with last billing date

4) Total volume in m³
5) Current power in kW
6) Current flow in m³/h
7) Current date
8) Error message (alternating binary and hexadecimal display)
2.
Level / Technician’s Loop
1) Maximum power in kW
2) Maximum flow in m³/h
3) Forward flow temperature in °C
4) Return flow temperature in °C
5) Temperature difference
6) Days in operation since verification
7) Sensor type / installation Position
8) M-bus address
9) Serial number of the heat meter
10) Firmware / software version
3. Level: Statistics Loop
1.) Previous billing date alternating with its value. Alternatively, the total
volume, tariff values, or values of individual instruments connected to
the optional pulse inputs can be displayed, if so set.

Up to the end of the month the consumption and reading date for that
month will be shown as 0.
9. Interfaces and Options
9.1. Optical (infrared) interface
In order for a PC to be able to communicate with a
SensoStar 2U® instrument, it is necessary to connect an
USB interface of the PC. The optocoupler and the
necessary software „Device®Monitor“ are optionally
available.
Baudrate (2400 Bd)
The optical infrared interface is activated with the key. If
within 60 seconds neither a valid telegram is received
nor the push-button pressed again, the interface is
deactivated.
9.2. M-Bus
With the optional M-Bus the protective interface is
galvanically separated. In a maximum-sized M-Bus
network of 250 meters, 24 read-outs per day are
possible for each meter. If fewer read-outs are carried
out and/or fewer heat meters are installed in the network
(connected to the M-Bus system), the unused amount of
available read-outs is stored in the instrument to be used
when needed.
