Installation instruction
RWA - Control Unit EMB 7300
Connecting wind and rain sensors
The system software offers the option to adapt the
response threshold of the wind sensor to the local con-
ditions. The factory default setting is 5 m/s. Further
modifications of the standard configuration require a
paid licence for the software.
Only connect when disconnected from the mains pow-
er supply! Switch off power supply and secure against
reconnection!
!
!
Cable installation must be in compliance with applicab-
le legal requirements. The terminal cross section for the
rain sensor must be minimum 1,5 mm², for the wind sen-
sor minimum 0,5 mm².
In case of fire (EMERGENCY-OPEN) or failure of power supply (accu-
mulator operation) the ventilation control via wind and rain sensors is
deactivated.
Before mounting and positioning the wind/rain sen-
sors carefully read the safety and assembly instructions
provided with the products. They are part of the system
documentation and must be adhered to and kept accor-
dingly (e.g. for servicing purposes).
