WBT-2201
BUILT-IN TRANSMITTER
ON/OFF AND PUSH DIM
2 CHANNELS
Built-in transmitter for wireless control of System Nexa
On/O and dimmer receivers and wireless doorbells.
The WBT-2201 has inputs for control via a resilient switch and
an alternate switch. The receiver is fully compatible with all “self-
learning” System Nexa receivers.
SAFETY
Read all the instructions carefully rst. 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.
Do not attempt to repair the product. The product contains no
serviceable parts.
INSTALLATION
Connect the switch according to the diagram for the relevant
function. It is possible to connect two types of switch to the WBT-
2201, depending on the type of receiver that is to be controlled;
see the circuit diagram for details. Please note that switches must
not be connected to 230 V.
PROGRAMMING
In order to use the WBT-2201 to control System Nexa receivers,
sender and receiver must be linked together as follows:
1. Connect the WBT-2201 and remove the protective tab from the
battery – alternatively, insert a battery.
2. Set the receiver that is to be linked to the WBT-2201 to
programming mode. See the receiver instruction manual for
additional information. (www.nexa.se/manualer)

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 re.
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 aected by disruptions that
may have an impact on performance and range. The minimum
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.
Waterproong: 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.
