  The receiver must be wired with the power supply switched off. 
Mains voltage may be switched on again only after the unit is completely 
mounted. 
•  When mounting the unit, the base must first be fitted and wired (L/N = AC 230 V 
mains supply, LX/L1 = consumers). Then, engage the unit at the top, swing it down-
ward and secure it with a screw 
•  For more detailed information, refer to the Installation Instructions supplied with the 
unit 
For the electrical installation, the local safety regulations must be complied with. 
•  Remove the battery transit tab: As soon as the battery transit tab is removed, the 
unit starts to operate. 
•  If possible, mount receiver temporarily in a first run (e.g. double coated tape). Doing 
that, location of best RF reception can be identified later on. See clause “5 Find lo-
cation of best reception“ 
•  Completely wire and mount REV-R.03/1 temporarily (please also close front cover) 
a)  Switch on power at REV-R.03/1: LED_1 lights always in red or flashes in red 
b)  Press the "RESET“ button on REV-R.03/1 for about 4 seconds: The orange LED_2 
will flash very fast and briefly (stored address of REV23.03RF will be erased) 
c)  Press the "SET“ button (set / learn) for about 3 sec. until the orange LED_2 starts 
flashing slowly and continuously: Receiver is now in learning mode 
d)  The receiver stays max. 25 minutes in learning mode. If no learning telegram from 
REV23.03RF is received during that period of time, repeat steps b) and c) again 
e)  Press the ESC button 
 on REV23.03RF for about 4 seconds. Learning tele-
gram is transmitted 
f)  If REV-R.03/1 receives learning telegram, the orange LED_2 flashes fast and 
briefly 
g)  If the orange LED_2 is steady on, the relay is energized (= controlled device ON) 
h)  If the orange LED_2 is dark, the relay is deenergized (= controlled device OFF) 
i)  Depending on the operating state, REV23.03RF repeats the ON or OFF control 
telegram every 3 minutes. With this the relay will be switched ON or OFF according 
to control telegram latest after 3 minutes 
j)  If REV-R.03/1 does not receive any correct control telegram within 60 minutes, 
controlled device is being switched off and LED_1 flashes in red 
k)  In the event of a power failure at the REV-R.03/1, the relay will be deenergized.
