Siting note for wall mounting:
1.3 REA-R.03/1 (receiver)
•
The receiver and switching unit should preferably be mounted
near the actuating device
•
Make certain that the mounting location is dry and protected
from splash water
•
The unit can be fitted to most commercially available recessed
conduit boxes or directly on the wall.

Check wiring

For the electrical connections, refer to "Connection diagram".
Note: Do not use stranded wires, only solid wires
or stranded wires with ferrules.
Commissioning RF Set
1 Switch on REA23.03RF
•
Remove the battery transit tab (also refer to Fig. F): As soon
as the battery transit tab is removed, the unit starts to operate.
2 Mount REA-R.03/1 temporarly
•
If possible, mount receiver temporarly 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 location of best reception"
•
Completely wire and mount REA-R.03/1 temporarly. Proceed
according Fig. H to M (please also close front cover)
3 Link REA-R.03/1 with REA23.03RF
a) Switch on power at REA-R.03/1: LED_1 (Fig. H) lights always
in red or flashes in red
b) Press the "RESET" button on REA-R.03/1 for about
4 seconds: The orange LED_2 (Fig. H) will flash very fast
and briefly (stored address of REA23.03RF will be erased)
c) Press the "SET" button (set / learn) for about 3 sec. until the
orange LED 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 REA23.03RF is received during that
period of time, repeat steps b) and c) again
ESC
e) Press the ESC button
4 seconds. Learning telegram is transmitted
f) If REA-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, REA23.03RF 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 REA-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 REA-R.03/1, the relay will
be deenergized.

3 Notes
•
The local regulations for electrical installations must be
complied with
•
If the reference room is equipped with thermostatic radiator
valves, they must be set to their fully open position
•
In the event of a power failure at the REA-R.03/1, the relay will
be deenergized.
•
If in normal operation REA-R.03/1 does receive for more than
25 minutes a very weak or no control telegram from
REA23.03RF, LED_1 starts to flash in red.
If control telegram is still understood correctly, receiver
continues with normal operation. If control telegram is not
understood anymore, relay remains in last position being
switched to before.
As soon as REA-R.03/1 does receive any correct control
telegram from REA23.03RF again, receiver continuous with
normal operation
•
In case of error, REA-R.03/1 switches off relay approximately
60 minutes after reception of last correct control telegram.
The controlled device is also switched off and LED_1 flashes
in red.
As soon as REA-R.03/1 does receive any correct control
telegram from REA23.03RF again, receiver continuous with
normal operation
•
Site REA23.03RF at preferred location for mounting at wall or
setting up with stand. Remove the unit from its base by
proceeding according to Fig. A:
- for wall mount, refer to Figs. B, C and D
- for set up with stand, refer to Fig. E
•
Also refer to "Mounting and siting notes REA23.03RF and
REA-R.03/1"
5 Find location of best RF reception
a) Switch off power at REA-R.03/1
b) Switch on REA23.03RF, site at prefered location and press
override button for about 4 seconds: REA23.03RF
transmits test telegrams every 2 seconds. Transmission of test
telegrams stopps automatically after 10 minutes or after
pressing either "ESC" button or override button
c) Switch on power at REA-R.03/1
d) Observe both LEDs on REA-R.03/1 from a distance of
2...3 meters
e) Orange LED_2 must flash briefly every 2 seconds.
Does LED_2 not flash every 2 seconds, distance between
REA23.03RF and REA-R.03/1 is too far. Mount REA-R.03/1
closer to REA23.03RF
f) LED_1 shows received signal strength of last telegram:
LED_1 flashes red: Signal is too weak to get a durable
durable link. Mount REA-R.03/1
closer to REA23.03RF
LED_1 flashes green: We distinguish between three
signal strenghts:
Very good (flashes 3x),
Good (flashes 2x) and
satisfactory (flashes 1x).
As soon as LED_1 flashes in green,
link between REA23.03RFand
REA-R.03/1 is basically ok.
g) Move REA-R.03/1 within an area of approximately 1 square
meter to find location of best RF reception. Always observe
LEDs from a distance of 2...3 meters.
To get a durable link, we recommend to site REA-R.03/1 at
a location where signal strength is at least "Good".
