Frequently Asked Questions

V-Pro IR and V-Pro Eclique Dimmer Series

1. My LED lamps glow or flicker when the dimmer is switched off.

All touch and remote dimmers have a standby current, much like a television, so that they will respond to an infrared (IR) signal. Some LED lamps are sensitive and will remain on even though the standby current is very low. We have created a device called a 'GlowFix' (part number 'YAGF') to combat this problem and one 'GlowFix' connected in parallel with the LED load will stop sensitive LED lights from glowing or flickering. Another solution would be to use a V-Pro push on/off rotary dimmer.

2. My slave units only turn the lights on; they don't turn the lights off or dim them.

Some LED lamps can interfere with the operation of dimming slave units. Please follow the steps below for the procedure known as 'Ranging'.

1.Turn the power off at the MCB and switch back on again after 5 seconds.

2.At the Master dimmer, press and hold the touch/tactile-touch button. When the lights reach full brightness the lamps will turn off.

3.Adjust the brightness up and down a few times and then switch off.

4.Try controlling the lights from the slave unit.

Please note that the touch/tactile-touch button should not be held for more than 12 seconds at anytime during this procedure. If this procedure does not cure the behaviour you are experiencing, please contact Varilight Customer Services.

3. My master dimmer does not respond to my remote control.

We would recommend performing a factory reset on the dimmer and then programming it to the remote control again. Please refer to your instruction leaflet or view the instruction leaflet on this website for details of each of these procedures.

If you are using dimmable LED lamps it may be of benefit to change the driving mode of the dimmer to mode 2 before programming the dimmer to the remote control again. Instructions on how to change the driving mode are located in the product instruction manual.

4. My lights are turning on/off at random

The most likely reason this is happening is that the dimmer has not been programmed to a remote control correctly. We would recommend programming the dimmer to the remote control again, making sure to confirm the selected button on the remote.

When programming the switch to the remote, we would recommend only a very short press on the selected remote button, not a long press.

5. My lights respond to IR but not to touch

This problem usually occurs when the dimmer is switching neutral rather than switching live. Please check your wiring against the diagram below.

6. My lights are no longer dimming

We would advise to perform the factory reset on the dimmer switch. Instructions on how to do this are located in the product instruction manual and on Varilight TV.

If you have performed and the factory reset and the lights are still not dimming, please contact Varilight Customer Services.

7. My lights flash 2 or 3 times before staying on

This behaviour occurs when the dimmer is detecting too much current draw from the lamps on startup, therefore it charges the lamps in steps in order to protect itself. Changing the driving mode on the dimmer switch may improve this behaviour. Instructions on how to change the driving mode are located in the product instruction manual and on Varilight TV.

8. My LED lamps are buzzing whilst the dimmer is on

This behaviour can be attributed to a component within the LED lamps themselves vibrating during operation. Changing the driving mode on the dimmer may improve this behaviour. Instructions on how to change the driving mode are located in the product instruction manual and on Varilight TV.

If the LED lamps continue to buzz after trying the different driving modes we would recommend contacting the LED manufacturer for further advice.

All V-Pro Series Dimmers

9. My LED lamps flicker/turn off at high/low brightness levels

The behaviour of LED lamps can be improved by changing the driving mode on the dimmer switch.

If the lamps are flickering at the bottom end of the dimming cycle you can also adjust the minimum brightness on the dimmer switch.

Instructions on how to change the driving mode and the minimum brightness setting can be found in the product instruction manual.

10. I've changed the load on my dimmer, is there anything I need to do?

If you have recently changed the load we would advise to perform the factory reset on the dimmer switch. Instructions on how to do this can be found in the product instruction manual.

11. My LED lamps do not switch off when the dimmer enters programming mode

When the dimmer enters programming mode there is a small amount of current that passes through the module to allow the dimmer to be reconfigured. Some LED lamps are extremely sensitive and will glow even though the dimmer is effectively off. You should still be able to complete the programming procedure however if you are not certain, we would recommend to change one of the LED lamps for an ordinary halogen/filament lamp, just for the duration of the programming, as this should prevent the LED lamps from glowing when they should be in their off state.
