ATTENTION

Double assignments of bus addresses are not permissible and inevitably lead to errors in data transmission and thus to faulty control behaviour of the heating system.

Changing bus addresses

A bus address can be changed at a later time using the following procedure:

•Disconnect wall devices from the data bus line (disconnect plug connection at the bottom of the device)

•Reconnect the wall device, holding the input button pressed down until the address setting screen is displayed.

•Set and confirm the new bus address.

7.3.11.3.2Operation with wall device SDW 10

Function A wall device SDW 10 can be connected to the control device.

With an SDW 10, it is possible to detect the room temperature, adjust the room setpoint temperature and change the control mode for a heating circuit remotely. The settings only apply for the assigned heating circuit.

The bus address of the wall device is used to specify on which heating circuit the room sensor and the adjustment of the control mode are to act.

The connection is carried out via the data bus.

Setting the bus The address of the SDW 10 is set by means of the rotating address encoding switch on the inside of the wall device in accordance

with the following table:
