Mains directly dimmable LED lamps.
Mains directly dimmable CFL lamps.
Dimmable LV electronic transformers.
Isolate the mains supply.
Remove the retaining screws and carefully withdraw accessory from wall box to reveal connections at rear.
Check that no mains voltage is present within existing accessory by use of 240 volt test-lamp (if available).
Disconnect all cables noting their respective connections.
Bend back the top and bottom wall box mounting lugs if present.
Ensure the wall box is free from dust and debris.
Connect accessory – see connection Diagram.
Check all connections thoroughly.
Mount accessory, taking care not to trap any cables beneath plate fixing screws. Do not over-tighten the fixing
screws. This may cause damage which could invalidate the warranty.

LEDstat Dimmer
Initial Start Up Settings:
The following instructions are to enable the first time set up or when the dimmer has been disconnected from the
mains supply (e.g. power cut). We recommend that all lamps in the circuit are of the same type and manufacturer.
Icons indicate when the dimmer needs your input.
Switch on dimmer on by pushing control knob
Allow dimmer to go through auto detect cycle. The light levels will raise and lower AUTOMATICALLY.
When complete the dimmer will either emit one long audible beep or three beeps, depending on load
Dimmer will AUTOMATICALLY power off.
Turn dimmer on by pushing the control knob.
Turn control knob clockwise to raise lighting level.
At full light level dimmer emits beep.
Turn control knob anticlockwise to lower to minimum setting
At lowest level the dimmer will emit an audible beep.
Manually Setting Minimum Light Level:
Should you not be happy with the minimum light level, this can be manually adjusted by the following procedure.
With dimmer in the OFF POSITION press and hold the knob continuously
Dimmer will come on and rise to full light level, then light level will lower and lamps will go out.
Immediately turn the knob clockwise. The lamps will come back on. Adjust to required minimum lighting
Once your desired minimum brightness level is achieved. Push the dimmer knob once to store the setting.
Lamps will turn off:
This action EXITS the manual programming mode.

LEDSTAT Trouble Shooting
1. The lights do not come on:
The dimmer module may be incorrectly wired, require resetting or have been overloaded.
Please check the module is correctly wired and ensure there are no short circuits. The dimmer has short circuit protection and will buzz repeatedly if a short circuit is detected.
Please reset the dimmer module. Disconnect and reconnect the mains supply to the lighting circuit at the consumer unit or fuse box by switching off the appropriate MCB or RCBO for a minimum of 5 seconds.
If the dimmer seems unusually warm it may have been permanently damaged due to overloading. Please
refer to troubleshooting for “The dimmer plate is getting usually hot” before replacing the dimmer.
If none of the above is successful please refer to your Wandsworth supplier or electrical contractor.
2. The lamps flicker.
The dimmer module may be operating in the wrong mode, possibly following a power cut or interruption to the mains
Please disconnect and reconnect the mains supply to the lighting circuit at the consumer unit or fuse box by
switching off the appropriate MCB for a minimum of 5 seconds. The dimmer should then auto detect the dimming mode next time it is operated.
If this is not successful the dimming mode may need to be set manually. Please refer to “Manually setting
minimum light level” on page 3 in the user guide.
The lamps may not be fully compatible with the dimmer module. Please consult your Wandsworth supplier or
3. The dimmer plate is getting unusually hot.
Please note all dimmer modules generate some heat as a small amount of the energy used is dissipated by the module. Up to 40°C (60°C for a plastic plate) above ambient temperature is considered acceptable under EN BS 60669-2
Ensure the load is below the recommended maximum (100w for trailing edge mode, 75w for leading edge
Some older leading edge LED lamps and drivers have a very high inrush current which may require the dimmer to dissipate excessive heat. In this case you may need to reduce the number of fittings or change the
lamp and/or Driver
No decorative, abrasive or domestic cleaning products should come into contact with the accessory (
It should not be used in areas of high humidity (bathrooms etc.), nor within reach of a water source.
This equipment should be connected to a mains supply of the appropriate voltage (indicated on the product).
Care should be taken not to overload the equipment maximum amperage (indicated on the product/packaging).
If you are unsure consult a qualified electrician before installation. No liability can be accepted if the product is installed
or used in any other way than for which it is designed.
