Connection 4 X Wind/Rain Control Units (Master/Slave Operation), 1 X Vent Switch 24 V And Dip Switch Settings - STG-BEIKIRCH WRZ 40M-4G Bedienungsanleitung

6.7 Connection 4 x Wind-/rain control units (master/slave operation),
1 x vent switch 24 V and DIP switch settings
The WRZ 40M-4G offers the possibility of connecting three further control units through a bus line. This allows a master
/ slave operation. The main control unit is the master. The main control unit issued orders to all other slave control units
via a bus line. Also the wind / rain message is forwarded via the bus line to the slave panels.
Each control unit must be supplied with power (230V AC). On the slave control units individual DIP switch settings have
to be made. About a vent switch 24 V, which is connected to the master control unit, all the connected drives (230 V) can
be drive central opened and closed. For this purpose the DIP switch 1 must be set at the Master control unit.
In this connection example, the drives can be connected directly to the control unit (without vent switch 230 V) at the
terminals CLOSE, N, OPEN.
After pressing the vent switch the terminals for the drives (CLOSE or OPEN) are supplied for 3 minutes with voltage.
After that there is no more voltage.
