Connection options for the expansion PCB - SCB-10

control of 2 (mixing) zones fitted on connector X15
control of a third (mixing) zone via an PCB (= accessory) fitted on
connector X8
control of one domestic hot water (DHW) zone
cascade layout (add sensor on sensor system 1 or 2)
Important
If the boiler is fitted with the SCB-10 PCB, then this is
automatically recognised by the automatic control unit of the
boiler.
On removing this control board, the boiler will show an error
code. To prevent this error, carry out an auto-detect immediately
after removing this board.
