Setting the S-Bus service pin
With a small screwdriver or paper clip, can be actuated the service pin by the vents.
Service-Pin
When the "Service pin" button is pressed, the compact room controller enables an
additional station address 252 for a minimum of 15 minutes. The controller can use
this address to communicate with the master independently of all other software com-
ponents. Provided that the room controller is receiving telegrams via this address, the
timer for time monitoring is restarted each time. Only when the timer expires (after 15
minutes) is station address 252 deactivated.
Please note that two controllers cannot be activated at the same time via the ser-
vice pin.
To terminate the timer prematurely, register 60 can also be manually set to 0, e.g. via
the Setup FBox, a communication FBox or the debugger.
Setting the station address
The station address can be parameterised via the Setup FBox or directly in regis-
ter 110.
Example:
Addressing using a Saia PCD
®
and FBoxes
- Activate station address 252 on the room controller by pressing the
"service pin" button
- In the case of correct S-Bus communication, the Connect output on
the FBox will be 'high'.
- Open Setup FBox, Adjust window.
- If communication is "online", enter a new station number, copy to the
Saia PCD
®
and click the "Setup" button.
Example:
Addressing with a Saia PCD
®
via the debugger
This requires a gateway to be parameterised in the Saia PCD
®
hard-
ware settings and the SASI master FBox.
- Activate station address 252 on the room controller by pressing the
"service pin" button
