Xylem sensus PolluStat Operating Instructions Manual page 50

The radio function can only be deactivated using the software "Device Monitor".
After activation of the radio function or modification of the radio parameters the meter remains in installation mode for 60
minutes. During this time he sends telegrams in a 36-seconds-interval.
If using the compact mode, after activation the meter transmits during installation mode format telegrams and compact
telegrams alternately.
During installation mode at least one meter of the version being installed (inlet or outlet flow, heat or heat/cooling, pulse
inputs, display units) must be read out with the Sensus "DIAVASO". The format of the telegram will be stored locally in the PC in
an .xml file.
After completion of the installation mode only compact telegrams will be transmitted.
1.4.1.4 Later activation of the radio encryption
The AES encryption can also be activated later. It can be activated as follows:
a) The encryption can be activated by pressing the push-button.
Press the push-button until you change to the display loop "6" (module loop). Then change with a
brief keystroke to the 3rd item "AES off" (see picture).
In order to start the editing mode you afterwards must press the push-button
once again for 2-3 seconds. As an aid, after 2 seconds the "editing pen" will be
displayed bottom left in the LCD. As soon as it appears you have to let go of
the button. Now the display shows "AES on" (see picture).
b) The encryption can also be activated using the software "Device Monitor". This software can be ordered separately as an
option. The encryption can only be deactivated using the software "Device Monitor".
