1.4.1.3 Activation of the radio interface
The radio interface
leaves the factory deactivated
. It can be activated as follows:
a) The radio function 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 2nd item “rad(io) 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 “rad(io) on“ and in all display loops a black
triangle (see picture).
b) The radio function can also be activated using the software “Device Monitor”.
This software can be ordered separately as an option.
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 Engelmann “Read-out Software walk-by”. 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”.
