Appearance, Function and Applications

This dimmer is push on/off and rotary controlled, meaning to turn the dimmer on or off simply push the dimmer knob in and it will click back out; then to turn the brightness up or down, rotate the knob clockwise and anti-clockwise.
..................................................
V-Pro Push on/off dimmers are also suitable for either 1 way, or 2 way circuits. What does 1 or 2 way mean? It means you are able to use this type of dimmer for both 1 way circuits (1 dimmer controlling 1 light) and 2 way circuits (1 dimmer and 1 switch controlling the same light). If the lighting circuit is controlled by 1 dimmer and 2 switches (3 way), in seperate locations then one of the switches in the circuit must be an Intermediate Switch with four terminals enabling you to link all three switches together.
..................................................
The V-Pro Series are programmable intelligent dimmers with a choice of dimming modes for wider compatibility. All V-Pro dimmers offer superior dimming technology to deliver the best possible dimming performance for numerous applications.
..................................................
V-Pro Series dimmer switches are trailing edge by default, Mode 1, this versatile mode is suitable for most dimmable LEDs and is also gentler on the load. Some types of dimmable LED perform best with Leading-Edge control, Mode 2 on the dimmer. Mode 3 is suitable for some external LED drivers. The driving modes can be easily changed by following the instructions under 'Programming' as shown in the dimmer instructions manual.
..................................................
The V-Pro series also have some other exclusive functions including; Adjusting The Minimum Brightness: If your lights are flickering at a low level or the lights are brighter than you would like when the dimmer is set to the minimum, this can be adjusted; Adjusting The Maximum Brightness: If your lights are flickering when they are set to a high brightness level or if the lights are not as bright as you would like, this can be adjusted; Drive Function: Some LEDs require a large amount of power to come on and so do not illuminate at low brightness levels, this can be adjusted; Child Lock: Prevention of your dimmer accidently going into programming mode; Resetting The Dimmer: If you change your lights you can reset the dimmer to factory settings which defaults the minimum brightness and re-launches Trailing Edge Mode 1. All of the V-Pro functions can be changed after the dimmer is installed, please see instructions manual.
..................................................
The V-Pro Series were primarily designed for Dimmable LEDs, the dimmers, can operate the majority of quality dimmable LEDs on the market, it works especially well with the manufacturers, Megaman, Philips and Integral, and any of the LEDs that we sell. They are also suitable for most dimmable electronic transformers, with no minimum load, especially Varilight's transformers.
..................................................
When using Electronic Low Voltage Transformers we recommend that a maximum of 5 good quality dimmable Electronic Transformers are used (10 if Varilight Transformers) with this dimmer range. Please note: add the watts of the bulbs/lamps if using Varilight Transformers, to determine which wattage of dimmer to select, but if using another manufacturer of Transformer, add up the VA of the Transformers so it does not exceed the maximum of the dimmer. Please note that noise levels can depend on the quality of the Transformer being used.
..................................................
The V-Pro Series are equipped with some intelligent features: Soft-Start Technology, allows a longer life span of the bulbs or lamps used by increasing the brightness level softly, which also creates a welcoming effect; Self Re-setting Overload Protection, so is able to handle overload situations, for example, if the wattage of the bulbs/lamps are accidentally too high on a circuit. This is achieved by either, stepping down the dimmer's output to the lamps (if the watts are marginally overloaded), or the dimmer cuts out before there is any damage, (if the watts are grossly overloaded), until the load is reduced; Intelligent Thermal Protection which again stops damage to the dimmer, if it becomes too hot.
..................................................

2 Way Dimming

The V-Pro Series Push on/off Dimmers can be used in 2 way circuits (where one lighting circuit is controlled from two locations). In order to achieve 2 way switching, they must be paired with a standard 2 way switch in the other location
3 way switching can be achieved by adding an intermediate switch in to the circuit. When using V-Pro Series Push on/off Dimmers in a 2 or 3 way circuit the lights can only be dimmed from the location that the dimmer is situated in, if total dimming is preferred from many switched locations, in a 2, 3 or more way circuit then choose the Varilight Smart or Multi-Point range of dimmers.
..................................................

Limitations

The best dimmer series for dimming Electronic Low Voltage Transformers, including dimming more than 5 Transformers, is the V-Plus Series, which has many features including Overload Protection; Soft Start which is gentler on the load; and Dimmer Buzz Elimination, that can be created from the transformers. V-Plus can NOT dim LEDs.
..................................................
Varilight Dimmers can NOT be used for wire-wound or torroidal Transformers. For Fan applications choose V-Dim Solid State Series, please check with manufacturer of appliance to be dimmed.
..................................................
For dimming lighting panels such as LED or CFL, choose the V-Com Series.
..................................................
These Dimmers are NOT suitable for TRIAC compatibility LED dimming, for this type of dimming, choose the V-Com Series.

Cleaning

This product can be easily cleaned with a soft dry micro-fibre cloth. Never apply masking tape or other similar tape to the product. Avoid the use of any cleaning chemicals and always use a Gasket on freshly plastered, painted or damp walls as the plates may tarnish. (Plaster can take up to 6 months to dry out). A Gasket can be made from the packaging the product comes in, or a plastic bag can be cut to stop the plate touching the plaster. Unfortunately, if these Instructions are not followed, and the plate is damaged, it will void the product warranty.
