Data bus boiler control unit A
B Data bus boiler control unit B
Here, only connect the first MadQ of the data bus connection!
Only connect the A-B data bus boiler control unit (RS485) of the boiler control unit after the first MadQ
control unit from position 20-21 in the boiler to position A-B on X11 in the wall-mounting case. Every
following MadQ control unit (up to 5) must be connected to the A-B data bus (T2B) from position 1 to
X6 and X5.
