Quick Start Guide Installation IMPORTANT: Turn o the mains electrical supply. Ensure that the wall (back) box has a minimum depth of 35mm. Remove and disconnect the existing lightswitch (if applicable). It may be useful at this point to mark out or take a photograph of the connections to the existing switch so that the correct wires can easily be transferred to the new dimmer.

Be aware that existing wiring circuits are not always correctly coloured, and that there may be other wired connections present in the back box;...

Installation Replace the plate – a ‘click’ sound should be heard to signify that the plate has been correctly replaced. Important things to consider • In a multigang dimmer, to be able to operate any gang, mains electricity must always be connected to all of the dimmer terminals.

Installation Connecting to a 2-Way Dimmer • Any LightwaveRF dimmer switch (and any gang in a multigang dimmer) can be used in conjunction with a LightwaveRF 2-way dimmer to perform 2-way switching. For full instructions on how to install a 2-way dimmer, please consult the instruction booklet for the 2-way dimmer.

Compatibility & Lamps Compatibility Ensuring the compatibility of your lamps (bulbs) with LightwaveRF Dimmers will ensure that you get the best experience from your lighting setup. LightwaveRF dimmers are compatible with the following: • Selected dimmable LED lamps (see www.lightwaverf.house for further guidance and information).
Page 13
Compatibility & Lamps Adjusting the dimming range On initial setup, LightwaveRF Dimmers are pre-programmed to allow a moderate range of dimming for any connected lamps. If desired, this range can be extended by following the instructions below. The reason for allowing modifications to the dimming range is to maximise compatibility with dimmable LED lamps (bulbs).
Page 14
Compatibility & Lamps Tap the (top) ‘on’ button twice to enter Dimming Range Setup. The blue LED will flash to indicate that the setup menu has been accessed. The dimmer will automatically turn on at a high level of brightness. This indicates that the smallest (most stable) dimming range is currently selected.
Page 15
Compatibility & Lamps Important things to consider • Wattage ratings for the dimmers are per gang. This means that a total load of 250W (incandescent) can be put on each circuit connected to each gang. • LightwaveRF Dimmers utilise a tiny amount of power to drive the electronics that operate the RF radio and dimming components.
Manual Operation Manual operation Manual dimming • Tap the ‘on’ (top) button once to switch the dimmer on (blue LED indicator will illuminate). Press and hold the ‘on’ button to raise the light level. • Tap the ‘o ’ (bottom) button once to switch the dimmer o (amber LED indicator will illuminate).
6 LightwaveRF controllers in total. If you are using a smartphone/tablet/PC to control the dimmer via the Lightwave Link, this will always count as ONE controller and take up one memory slot even if you are using multiple smartphones/tablets.

Device Setup NOTE: Linking mode lasts for 12 seconds; if no signal is received from a remote handset during this time then the dimmer will automatically exit learning mode without linking the device. If, when expecting a blue LED flash to confirm pairing, a slow amber LED flash is received instead, the dimmer switch memory is FULL and no further remotes may be linked with it unless one of the existing remotes is first unpaired (see below).
Page 19
LED will flash to confirm that the NOTE: Reliable range of remote operation is around 15 metres indoors and up to 100m outdoors (using a Lightwave Link). This figure may vary depending upon the environment; very thick walls, bodies of water or large metal objects may interfere with radio range.
Remote Operation Remote operation Dimming with the LightwaveRF App or a LightwaveRF controller • Press the ‘on’ button on the App (or other LightwaveRF controller) once to switch the dimmer (blue indicator will illuminate). Use the slider to raise or lower the light level (or press and hold the on or button on any other LightwaveRF controller).
Page 21
Remote Operation Locking the Dimmer Switch • The dimmer can be ‘locked’ so that the manual buttons will not operate it. This can be achieved using the LightwaveRF App or a ‘Socket Locker’ remote. If it is locked on, then the dimmer will not turn o manually.

Creative Ideas for Lightwave Dimmers 1. (Easy): Family safety Products Required: Dimmer Switch, PIR Motion Sensor Here we have a LightwaveRF Dimmer Switch paired to a PIR Motion Sensor. When somebody is detected by the sensor, it triggers the dimmer automatically and turns the light on.

At the end of the evening, press the ‘all o ’ button to turn o all lights and lamps. Adding the Lightwave Link allows scene lighting to be controlled via a smartphone.

This setup gives you control over your devices from anywhere in the world. Here we have ceiling lights controlled by dimmers and lamps plugged into Lightwave Power Sockets or Plug-in Sockets. Via the Lightwave Link, every light can be controlled using a smartphone wherever you are. So, when you’re away on holiday, you can turn on lights to make it look like someone’s...
Troubleshooting Problem: The dimmer will not operate the light and the LEDs on the dimmer do not light up. Solution: First, check that there is power to the dimmer. Make sure that the connected lamps are functioning correctly; the dimmer switch will not run unless it has a functioning lamp(s) to complete the circuit.
Page 26
The dimmer will not consistently operate remotely. Solution: The controller/Lightwave Link may be encountering interference or may be at the edge of its reliable range of operation. Ensure that there are no thick walls, large pieces of metal or bodies of water in the path of the transmission.
Page 27
How many devices can I have on the LightwaveRF system? Each device has 6 memory slots for up 6 controllers (one of these can be the Lightwave Link allowing up to 6 smartphones to control up to 240 devices. Can I use LED bulbs?
Page 28
FAQs Can I use non dimmable bulbs if I don't dim them? No. The bulbs must be dimmable even if they are not dimmed; the technology in the bulb must be compatible with that of the dimmer. What if I need a switch to operate on/o only? A LightwaveRF Relay in conjunction with a Wire-free Switch can be used for on/o switching in place of the dimmer (see www.lightwaverf.house).
