INSTALLATION
Make sure that the wires are free from voltage by disconnecting the
current in the electricity panel, then connect phase to L and Neutral
to N. The WBR-2203 features a potential-free relay contact and can
be used to control 230 V, low-voltage products, as well as products
that require potential-free connection – see the circuit diagram for
examples.
PROGRAMMING
In order to operate the WBR-2203 with a System Nexa remote
control (or other unit), the transmitter and receiver must be
connected as follows:
1. Connect current to the WBR-2203.
2. Briefly (<0.5s) press the “programming” button, the LED indicator
will start to flash slowly.
3. Press the “ON” button for the selected channel on a System
Nexa remote control within 12 seconds.
To program other System Nexa units (Motion detector, Magnetic switch,
Bridge, etc.) see the instructions for use for the respective products.
CONFIRMATION OF PROGRAMMING
The LED indicator next to the “programming” button flashes slowly
2 times.
DELETE MEMORY SLOT
1. Connect current to the WBR-2203.
2. Briefly (<0.5s) press the “programming” button, the LED indicator
will start to flash slowly.
3. Press the “OFF” button for the selected channel to be deleted
from a System Nexa remote control within 12 seconds.
To delete programming from other System Nexa units (Motion
detector, Magnetic switch, Bridge, etc.) see the instructions for use
for the respective product.
CONFIRMATION OF DELETION
The LED indicator next to the “programming” flashes slowly 2 times.
DELETION OF ALL MEMORY SLOTS
1. Connect current to the WBR-2203.
2. Press the “programming” button and hold it down for 6 seconds.
The LED indicator starts to flash quickly.
3. Release the “programming” button and then press it briefly once
more.
CONFIRMATION OF DELETION OF ALL MEMORY SLOTS
The LED indicator next to the “programming” button flashes slowly
2 times.

TECHNICAL DATA SAFETY AND INFORMATION
Range indoors: up to 30 m (optimal conditions). The range is heavily
dependent on local conditions – such as if there are any metals
nearby. For example, the heavy metal coating in low-emission
energy glass has a negative impact on the range of the radio signals.
There may be limitations on the use of the unit outside the EU. If
appropriate, check that the unit complies with the local regulations.
Max. load: Never connect lights or equipment that exceeds the
maximum load of the receiver. This can result in faults, short circuit
or fire.
Life support equipment: Never use Nexa products for life support
equipment or other devices where faults or disruptions can have
life-threatening consequences.
Disruptions: All wireless units can be affected by disruptions that
may have an impact on performance and range. The minimum
switches, Bridge, etc.). If all memory slots are filled, the oldest slot
will be deleted when a new channel is programmed.
CONTROL
The receiver can be controlled as follows:
1. With a programmed System Nexa Remote Control
2. With other programmed System Nexa transmitters.
3. With a Nexa Smart Hub.
4. With Nexa Bridge
5. With a resilient switch
SETTING THE TURN-OFF TIMER
The turn-off timer opens the relay contact automatically after the
set period of time has elapsed. The WBR-2203 is supplied set up
for manual On/Off operation.
1. Press the “Timer setting” button and keep it depressed (> 3 s).
The LED indicator for the “Timer” button flashes quickly 5 times
to confirm programming status; it then continues to flash at
3-second intervals. Number of flashes current setting (see table).
2. Briefly (<0.5 s) press the “Timer setting” button to select the next
setting from the table.
3. To save the timer setting, press and hold the “Timer setting”
button (> 3 s).
CONFIRMATION OF SETTING
The LED indicator in the “Timer” button flashes quickly 5 times to
confirm that the setting has been saved.

Built-in receiver for wireless control of, for example, lights,
automatic garage doors and gates, and ventilation units.
The product features inputs for control via a resilient switch,
potential-free relay output and turn-off timer. The receiver is fully
compatible with other System Nexa products.
SAFETY! Read all the instructions carefully first. Call in a
professional if necessary. Nexa cannot be held liable if the
product is used for any purpose other than that for which it was
designed, or if the associated instructions are not followed. Never
connect lights or any equipment that exceeds the maximum
stated load of the receiver, as this can result in faults, short circuit
or fire. Do not attempt to repair the product. The product contains
no serviceable parts.
A declaration of conformity is available online at www.nexa.se
distance between two receivers should therefore be at least 50 cm.
Repairs: Do not attempt to repair the product. It does not contain
any serviceable parts.
Waterproofing: The product is not waterproof. Make sure that it is
always dry. Moisture will corrode the electronic components inside
and may result in short circuit, faults and risk of electric shock.
Cleaning: Clean the product with a dry cloth. Do not use chemicals,
solvents or potent cleaning agents.
Environment:Do not expose the product to extreme heat or cold, as
this may damage the electronic circuits or shorten their service life.
