TECHNICAL DATA
A declaration of conformity is available at www.nexa.se
The WBT-230 is a transmitter for fixed installation. It is powered by
230 V AC and features two channels with 230 V AC as the input
signal.
INSTALLATION
Installation must be performed by an authorised fitter.
Make sure that the power supply is disconnected during installation.
Connect the WBT-230 to a power switch as shown below. The
transmitter is powered by 230 V. Connect the live (phase) wire to L
and the neutral wire to N. Connect the switch leg(s) to S1 and/or S2.
The WBT-230 can also be controlled by a twilight relay, an astro-
clock or other units with a 230 V output signal.
PUSH FUNCTION
When combined with a receiver relay, the WBT-230 can be used for
the wireless control of units via a push function. In this situation,
connect the WBT-230 to a power switch with an impulse spring and
connect a receiver relay to the input on the unit in question.
WIRELESS CONNECTION OF MULTIPLE CIRCUITS
The WBT-230 can be used to connect two circuits without having
to use signal wires/switch legs between them. For example, the
outdoor light on a garage could be switched on simultaneously with
the outdoor lights on the house.
Connect the phase and neutral wires to the WBT-230 and connect
S1 or S2 to the interrupted phase in the existing circuit. Then use a
receiver relay in the circuit you wish to control.
OTHER INFORMATION
Indoor range: up to 30 m (optimal conditions). The range is strongly
dependent on local conditions, such as the presence of metals. For
example, the thin metal coating in Low-emissivity (Low-E) glass has
a negative impact on the range of radio signals.
There may be restrictions on the use of this device outside the EU. If
applicable, check whether this device complies with local directives.
Maximum load: Never connect lights or equipment that exceed
the maximum load of the receiver, as it can result in defects, a short
circuit or fire.
Life-support: Never use Nexa products for life-support systems or
other applications in which equipment malfunctions can have life-
threatening consequences.
Interference: All wireless devices may be subject to interference,
which could affect performance. The minimum distance between 2
receivers should be at least 50 cm.
Repairing: Do not attempt to repair this product. There are no user-
serviceable parts inside.
