Lightwave LP81 Manuel utilisateur
Applicaons
The Smart Relay is a very versale device that can be
used to remotely switch on/o a circuit. Because the
relay includes one latching posion, it can be used to
operate devices that require an on/o control.
Loading
The Smart Relay can be used to switch loads of up to
700W. The switched circuit can be mains powered or
volts free (low voltage). Mains power can also be taken
from the Relay itself to power the circuit (see wiring
instrucons for more informaon).
Locaon
The Smart Relay needs to be housed in a suitable
enclosure to minimise the risk of contact with live
electrical wires and to ensure that the device meets
IEC Class II requirements. The Lightwave LW824
Waterproof housing can be used for this purpose and
will also allow the Relay to be installed outdoors.
Range
Lightwave devices have excellent communicaon range
within a typical home, however, if you encounter any
range issues, try to ensure that large metal objects or
bodies of water (e.g. radiators) are not posioned in
front of the device or in between the device and the
Lightwave Link Plus.

Environmentally friendly disposal
Old electrical appliances must not be disposed of
together with residual waste, but have to be disposed
of separately. The disposal at the communal collecng
point via private persons is for free. The owner of old
appliances is responsible to bring the appliances to these
collecng points or to similar collecon points. With this
lile personal eort, you contribute to recycle valuable
raw materials and the treatment of toxic substances.
Installaon
If you plan to install this product yourself, please follow
the electrical wiring instrucons carefully to ensure the
product is installed safely, if in any doubt please consult a
qualied electrician.
It is important to install this product in accordance with
these instrucons. Failure to do so may risk personal
safety, create a re hazard, violate the law and will also
void your warranty. LightwaveRF Technology Ltd will not
be held responsible for any loss or damage resulng from
not correctly following the instrucon manual.
IMPORTANT: Any electrical installaon must comply with
Building Regulaons, BS 7671 (IET Wiring Regulaons)
or local equivalent.
IMPORTANT: If conducng an insulaon resistance test,
any hard-wired Lightwave devices must be disconnected
from the mains, or damage to the unit may occur.
IMPORTANT: High-Power inducve loads can potenally
damage the device and are not recommended.

Installing the Relay
Carefully follow the instrucons in this secon in
order to install the Relay. Please remember that mains
electricity is dangerous. Do not take any risks. For other
advice, please contact our dedicated technical support
team at www.lightwaverf.com.
The easiest way to learn how to install the Lightwave
Smart Relay is to watch our short installaon video which
is accessible at
www.lightwaverf.com/product-manuals
1.1 Prepare a suitable locaon
The Smart Relay is a class 0 device which means that it
should be housed in a suitable dry locaon and electrical
housing to minimise the risk of contact with live electrical
wires. If in doubt, consult an electrician.
1.2 Turn o the electricity supply
Turn o the mains power supply to your exisng power
circuit at the consumer unit.
1.3 Connect to mains power
Although the Smart Relay can be used to provide volts
free (non mains) switching, it ALWAYS requires mains
power to operate. Connect the line and neutral power
cables to the Relay as shown in the diagrams. Be aware
that exisng cables can vary in colour and may not
always be correctly labelled. If in any doubt, always
consult a qualied electrician.

Linking the Relay & other funcons
Unlinking the Relay (clear memory)
To unlink the Relay, enter linking mode by holding down
the main buon unl the LED ashes red. Release the
buon, then hold it for a second me unl the LED
ashes red to conrm that the memory has been cleared.
Firmware updates
Firmware updates are over-the-air soware
improvements that keep your device up to date as well
as providing new features. Updates can be approved
from the App before being implemented, and generally
take 2-5 minutes. The LED will ash cyan in colour
during an update. Please do not interrupt the process
during this me.
Error reporng
A permanently ashing red LED indicates that a
soware or hardware error has been encountered.
Press the main buon to reset the device. If the error
light persists, please contact Lightwave support via
www.lightwaverf.com/support.
Follow the in-app instrucons which
will explain how to link devices.
On the Relay, press and hold down
the main buon unl the LED ashes
blue and red alternately then release it.
The Relay is now in linking mode.
Using the App, press the buon to link
to the device (the App instrucons will
guide you through this). The indicator
on the Relay will ash to conrm that
it is now linked.
Linking
To be able to command the Relay, you will need to link it
to the Link Plus.
1 Adding mains voltage to a circuit (A)
In this case, mains voltage is ‘jumped’ from the main
incoming line feed to the COM terminal by the
addion of a connecng ‘jumper’ wire. Mains power
can now be used to drive the single circuit illustrated
in diagram A.

Connect the circuit
The Smart Relay can be used to provide up to 700W of mains powered switching OR separate volts free switching for circuits not requiring addional mains power. The Relay latches between
NO and COM. Follow the instrucons below.

3 Switching a single circuit (C)
Use this conguraon to switch a single circuit
(can be low voltage) that does not require mains
power to be provided from the Relay’s line (L) and
neutral (N) terminals.
2 Switch sense (B)
In addion this device has a “switch sense” terminal
(diagram B) that can detect the ‘on’ or ‘o’ posion of
an external switch such as a normal light switch.
The acon of the external switch can then operate
the internal relay and / or be detected by the Link+
to trigger another device or devices or an automaon.
Any switch or circuit connected to the “switch sense”
input must be suitable for “230V AC” mains power.
4 Switch Sense (D)
The ‘switch sense’ relay output conguraon can be
230V mains (B) or volts free low voltage output (D).
