Smart
Dimmer
Get the best out of your install This Lightwave Smart Dimmer requires a 35mm deep back
box in which to mount it. If you have a back box that is
shallower than 35mm, then a Lightwave spacer can be used to
provide up to 10mm of extra clearance from the wall.

Hints and tips
Lightwave dimmers are designed to work with the majority
of dimmable LEDs, but, as every lamp can behave differently,
it is advisable to choose variants that have been tested and
proven to work well. If you plan to use LEDs, we strongly
recommend that you consult our compatibility chart (see
www.lightwaverf.com). The LEDs must be dimmable (not
all varieties are), and you should not exceed the maximum
loading recommendations provided on the compatibility
chart or damage could occur.

Quick Start Guide
Installing yourself?
Please note that all Lightwave products can be legally
DIY installed in your own home; however, if in doubt,
always consult a qualied electrician.
It is important to install this product in accordance with
these instructions. Failure to do so may risk personal safety,
could create a re hazard and will also void your warranty.
If conducting an insulation resistance test, any hard-wired
Lightwave devices must be disconnected from the mains,
or damage to the unit may occur.

Install the Dimmer
Carefully follow the instructions in this section in
order to install the Dimmer. Please remember that
live electricity is dangerous. Do not take any risks.
If in any doubt, consult a qualied professional.
For other advice, please contact our dedicated
technical support team on 0121 250 3625.

The easiest way to learn how to install the Lightwave
Dimmer is to watch our short installation video which
is accessible at
Turn off the mains power supply to your existing lighting
circuit at the consumer unit.
1.1 Turn off the mains electricity supply
Unscrew the existing light-switch and remove the wires. It is
often a good idea to take a quick photo of the existing wiring
conguration. This can help you to remember which wires connect
to which terminals if there are more than two, or if they are not
distinctly labelled. The existing wiring should be colour coded and
arranged as per the wiring diagram provided in these instructions,
however, please be aware that not all existing wiring will conform
to this standard and may differ.
1.2 Remove the existing switch
Remove the faceplate from the Lightwave Dimmer by carefully
inserting a screwdriver into the small slot located at the bottom
edge of the cover.
1.3 Remove the faceplate
Carefully wire the Dimmer as shown in the diagram. Be aware
that existing cables can vary in colour and may not always be
correctly labelled. If in any doubt, always consult a qualied
electrician. Replace the faceplate by hooking it onto the
top edge of the Dimmer and clipping in the bottom. Check
the wiring and load; remember not to exceed the 350W
incandescent load and to only use recommended dimmable
LED lamps.
1.4 Wire the Dimmer
Earth wire this should
also be connected to earth
terminal in the back box if
one exists (important when
using metal back boxes).
Switched live wire out.
This should be blue or
black in colour. It may be
marked by brown/red tape
to emphasise that it is not
a neutral wire.
Repeat wiring for
second dimmer gang
Live wire in.
This should be brown
or red in colour.

Please follow the in-app instructions which will explain
how to link devices.
On the Dimmer, press and hold down ‘on’ / ‘off’ button until
the LED ashes blue and red alternately then release it.
The Dimmer is now in linking mode.
Using the Lightwave App, press the button you want to link to (the
App instructions will guide you through this). The blue light on the
Dimmer switch will ash to conrm that it is now linked to the App.
Unlinking the Dimmer
To unlink the Dimmer and clear the memory, enter linking mode
by holding down both on/off buttons until the LED ashes red.
Release the buttons, then hold the off button until the LED ashes
rapidly to conrm that the memory has been cleared. On clearing
the memory, automatic calibration will be initiated.
Locking the Dimmer
The Dimmer can be ‘locked’ using the App so that the manual
buttons will not operate it. If it is locked on, then the Dimmer will
not turn off manually. A locked dimmer is signied by a slow ashing
magenta LED. To lock / unlock the Dimmer, press the ‘lock’ button
on the Smartphone App. Clearing the memory will remove the lock.
Changing the colour of the indicator LED
The colour of the LED indicator lights on the Dimmer can be
changed or the LED turned off using the Lightwave App. See the
App for more details.
Multi-way switching
Lightwave Dimmers perform 2-way or multi-way switching
wirelessly. This means that they can be wired into a circuit using
only a live in and switched live out, and communication between
them is carried out via wireless RF frequency. Dimmers can be
linked to perform multi-way switching using the ‘group’ automation
feature on the Lightwave App (see the App for more details).
Firmware updates
Firmware updates are over the air software 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 time.
Error reporting
A permanently ashing red LED indicates that a software or
hardware error has been encountered. Press the on/off button to
reset the indicator LED. If the error light persists, please contact
Lightwave support via www.lightwaverf.com/support.

Once the dimmer has been installed, lamps added to
the circuit and the power switched on, it will enter
calibration mode. This mode calculates the appropriate
settings and dimming range to maximise compatibility
with the lamps being used on the circuit.
On button
Tap to turn on
Hold to raise light level
Double tap to go to full brightness
Automatic calibration
If the dimmer has not previously been calibrated, it will automatically
calibrate itself to the lamps detected on the circuit after 5 seconds. If the
dimmer has been calibrated previously, these settings will be restored
unless the on button is pressed within 5 seconds to overwrite them with a
new calibration (recommended if lamps are changed). Auto calibration is
denoted by ashing green LEDs.
Manual calibration (use in the event of persistent lamp icker or instability)
Pressing the off button within 5 seconds of introducing power to the Dimmer
will initiate manual calibration. This is initially denoted by ashing green and
red LEDs. Pressing the on and off buttons now will extend or shorten the
lower dimming limit. Pressing both buttons together will save the setting.
Next, ashing green and blue LEDs denote that pressing the on and off
buttons will now alter the upper limit. Press both buttons to save this
setting.
