Installation of dual system
The installation of a DEVIreg™ 850 with 2 roof systems or 2 ground systems has been
selected.
It is mandatory that no sensors or only sensors for System A are connected to the
the DEVIreg™ 850 before power up. Sensors for System B must be connected to the
DEVIreg™ 850 during the installation steps. Connection of the sensors during instal-
lation can either be done using a switch on the DIN-rail or just connect sensor bus of
System B to the already connected sensor bus of System A.
The rst installed system (System A) is using the output System A.
The second installed system (System B) is using the output System B.
If sensors for System A are not connected - do it now!
