9.2 Operation of wall devices
9.2.1 Operation of wall devices RS
Function: A wall device RS can be connected to the controller.
With a wall device, remote control for a standard unit (e.g. from a living room) is
possible in addition to the room temperature detection. Settings can be carried out
for all the existing heating circuits.
The bus address of the wall device is used to specify upon which heating circuit the
room sensor (room influence) should act.
When an RS is connected for the first time to the bus system, the address is selected
for the heating circuit to which the RS is to be assigned (bus address).
After the input has been confirmed, a feedback is output to which heating circuit (HC,
MC1, MC2) and which standard unit (AU) the digital wall device has been assigned
Assignment is carried on the basis of the following table:
Caution:
Duplicate assignments of bus addresses are not allowed and will lead to data
transmission errors and, consequently, to control malfunctions of the heating system.
Changing a bus address
A bus address is can be changed at a later stage by the following procedure:
1 Disconnect wall devices from the data bus line (disconnect plug connection at the
bottom of the device)
2 Reconnect the wall device, holding the rotary-push button pressed down until the
address setting screen is displayed.
3 Set and confirm the new bus address.
