Connecting control unit to Viessmann 2-wire BUS system
The Viessmann 2-wire BUS communication module (accessory) must be plugged in (see parts list).
A Communication module
B Rotary dial
1. Set the rotary dial on the communication module in
accordance with the system version between 4 and C
(the rotary dial must not be set the same as the rotary
dial of another control unit).
Please note!
For wall-mounted boilers, if a actuator kit (PN. 7133 392)
for one mixing valve controller is used, the default rotary
dial position is #4. When connecting extra Vitotronic
050, set the rotary dial such that 4 is not duplicated.
2. In conjunction with a boiler control unit for wall mounted
boilers or Dekamatik system:
Adjust the differential temperature at the above control
unit.
On Vitotronic 050, set coding 9F : 0.
Set coding 97 : 1, if the outside temperature is to be
taken from an outside temperature sensor which is
already connected.
