6.11.2 Installation Mode
The  symbol indicates that the heat cost allocator is in
installation mode
During the installation mode all functions of the radio heat cost allocator 565 / 566 / 868 / 878
are carried out.

For heat cost allocator 566, the radio transmission is possible 24h/24h till at the end of the
second day at midnight. This guarantees an optimal availability of the radio heat cost
allocator for test purposes during installation.

For heat cost allocator 868, an installation telegram is activated during the installation
phase. Data are transmitted each 30 seconds (short and long telegram) till at the end of the
second day at midnight.

A network connection procedure is automatically performed for the heat cost allocator 878.
In case of a failed connection setup, this procedure is automatically repeated once a day
The heat cost allocator 565 / 566 / 868 / 878 switches automatically into operating mode at
the end of the second day at midnight.
If heat cost allocator is removed from the aluminium back plate during the installa-
tion mode, the heat cost allocator switches to the sleeping mode.

6.11.3 Operation Mode for Radio Sontex (566)
6.11.3.1 Walk-by Radio Remote Readout
A walk-by remote readout of the data of the heat cost allocator 566 is possible every day from
6.00 to 17.59 (winter time).
6.11.3.2 Readout over Radio Central or Gateway Superlink C (fix installed in building)
In the working mode, the heat cost allocator whose last serial number digit corresponds to the
following table is ready for radio transmission during the period specified below:
6.11.1 Sleeping Mode
Ex-factory the radio heat cost allocator is in sleeping mode, but the internal clock and the date
are running.
Current consumption is reduced to a minimum since no measuring and no calculations are
carried out. Only the optical communication interface is available.
Transition from sleeping to installation mode is achieved by pushing the button once the
heat cost allocator is mounted on the aluminium back plate or by an automatic commissioning
during the mounting on the aluminium back plate (must be specified when ordering).
When the device switches from sleep mode to installation mode, the following counters are
automatically reset to zero:

Current totaliser, totaliser at set day, historical totaliser values.

Max. radiator temperature.
