QAW850 Dip switches

The QAW850 includes dip switches for zone addressing. Up to 6 zones can be connected to an RRV856 controller.

Dip switches on the back of QAW850.

They allow setting the address in cases where several room

units are connected to one RRV856 controller.

The room units are delivered with default positions = zone 2

(address = 3).

The master room unit QAX850 is normally zone 1 al-

though a QAW850 can be addressed as zone 1 if re-

quired. In this case the QAX850 would serve as a mas-

ter control unit only.
