Bluetooth Smart Lighting with the Finder YESLY System

The Finder YESLY system enables lighting and other compatible electrical devices to be controlled using Bluetooth wireless technology. The Finder 15.71.8.230.B202 provides brightness adjustment within this ecosystem, allowing users to control not only whether a light is switched on or off but also the intensity of the illumination.

Bluetooth connectivity allows the dimmer to receive commands from compatible wireless push buttons and smartphones. The device uses Bluetooth 4.2 Low Energy with a 128-bit encrypted connection to support secure local wireless communication.

The approximate transmission range is 10 m in unobstructed free space. Actual range may be reduced by walls, metal enclosures, electrical equipment and the layout of the building.

Once configured, the dimmer can be incorporated into YESLY lighting scenarios. These scenarios allow compatible devices to respond to coordinated commands, helping users establish different lighting conditions for activities such as relaxing, entertaining, working or watching television.

The Finder 15.71.8.230.B202 supports up to eight scenarios. For remote control beyond local Bluetooth range, an appropriate YESLY gateway and network connection may be required.

Leading-Edge and Trailing-Edge Dimming Technology

The Finder 15.71.8.230.B202 uses phase-control dimming to regulate the power delivered to compatible lighting loads. By controlling the portion of each AC waveform supplied to the lamp, the dimmer can adjust brightness without requiring a separate low-voltage dimming interface.

Two principal phase-control methods are available:

• Leading-edge dimming: Controls the beginning of each AC half-cycle and may be suitable for certain compatible conventional and transformer-fed lighting loads.
• Trailing-edge dimming: Controls the end of each AC half-cycle and is commonly suitable for compatible dimmable LED lamps and electronic lighting drivers.

Different lamp technologies respond differently to these control methods. Using an unsuitable dimming method can result in flickering, restricted brightness adjustment, audible noise or unstable operation.

The Finder 15.71.8.230.B202 includes an AUTO function intended to help identify an appropriate control method for the connected lighting load. Installers can also select from seven manual dimming functions to adjust the phase-control method and brightness curve.

Because lamp electronics vary considerably between manufacturers, compatibility should always be checked against the lamp or driver manufacturer's dimming specifications.

Selectable Brightness Memory and Smooth Lighting Transitions

The Finder 15.71.8.230.B202 offers memory and non-memory dimming functions, allowing users to choose how the light behaves when it is switched on again.

With a memory function selected, the dimmer can restore the previously selected brightness level. This is useful in living rooms, bedrooms and other spaces where a preferred lighting level is used regularly.

Non-memory functions provide alternative switching behaviour where a predefined starting condition is more appropriate.

The device also provides soft on/off functionality, creating a smoother transition when the connected lighting is switched on or off. This can improve visual comfort compared with abrupt changes in illumination.

Installers can configure the minimum brightness threshold to suit the characteristics of the connected lamp. Correct adjustment is particularly important for LED lighting, as some lamps may flicker or switch off if the brightness is reduced below their stable operating range.

The dimmer supports both linear and non-linear adjustment curves, providing additional flexibility when tailoring the perceived brightness response to the application.

Compatible Dimmable LED, CFL and Halogen Lighting

The Finder 15.71.8.230.B202 is designed for use with several types of compatible dimmable lighting equipment.

Its nominal load ratings include 100 W for dimmable LED lighting and 200 W for halogen lighting. The maximum supported load depends on the lamp technology, the selected dimming method and the characteristics of the connected equipment.

Suitable applications may include dimmable LED downlights, decorative lamps, wall lighting, pendant fittings and other compatible mains-powered lighting products.

The dimmer may also be used with suitable dimmable compact fluorescent lamps and compatible transformer-fed lighting systems. However, not every LED lamp, CFL, electronic transformer or driver supports phase-cut dimming.

Non-dimmable lamps must not be connected for brightness control. Similarly, LED drivers intended exclusively for DALI, 0–10 V, PWM or other control protocols should not be assumed compatible with this mains phase-control dimmer.

When multiple lamps are connected to one output, their combined load and inrush characteristics must remain within the manufacturer's permitted limits.

Flush-Mounted Design for Residential Wall-Switch Systems

The Finder 15.71.8.230.B202 is designed for flush mounting in compatible residential switch boxes. Its front-mounted anthracite grey finish allows it to integrate with suitable decorative switch plates and wall-control systems.

The Type 15.71 design is associated with several popular Italian residential wiring accessory systems, including compatible ranges from AVE, Bticino, Gewiss, Simon-Urmet and Vimar. Appropriate mounting adaptors must be used where required.

The device can be installed in a suitable three-module wall-switch box, subject to the dimensions, wiring space and compatibility of the selected enclosure.

It operates from a 230 V AC, 50/60 Hz supply and uses screw terminal connections. The lighting load and wired push-button input must be connected according to Finder's relevant wiring diagram.

For installers, the specified 0.8 Nm terminal tightening torque and 9 mm conductor stripping length provide useful guidance for correct termination.

The dimmer has an IP20 protection rating and is intended for installation in a suitable dry indoor electrical environment. Its operating temperature range is -10 to +50 °C.

Installation should be undertaken by a competent electrician with the electrical supply safely isolated. Appropriate circuit protection, enclosure selection and conductor sizing remain essential.

Wired Push Buttons, Wireless Controls and Smartphone Configuration

The Finder 15.71.8.230.B202 supports one conventional wired push-button input, allowing lighting to be controlled using a compatible physical wall button.

It can also respond to compatible Finder YESLY wireless push buttons, including the BEYON and 013B9 control families.

This combination allows additional lighting control positions to be introduced without necessarily installing new control wiring. Wireless controls can be especially useful during refurbishment, when running cables through finished walls would be inconvenient.

Configuration is performed using a compatible Finder smartphone application. Depending on the supported software version, installers can select the dimming function, adjust operating parameters and associate compatible wireless controls.

The dimmer's Bluetooth connectivity supports local wireless control. It is not a standalone Wi-Fi dimmer, and internet-based operation depends on the use of compatible additional YESLY equipment.

Built-In Protection and Optional Leakage Current Suppression

The Finder 15.71.8.230.B202 incorporates thermal overload protection and short-circuit protection to help protect the electronic dimming circuit under specified fault conditions.

These internal functions supplement, but do not replace, the need for suitable external circuit protection and compliant electrical installation practices.

Some LED lamps may continue to glow faintly when an electronic dimmer is switched off because of small residual currents within the circuit.

For installations experiencing this behaviour, Finder offers the 015.0.230 leakage current suppression module. This optional accessory is designed to provide a bypass path for residual current and can help eliminate unwanted illumination when the dimmer output is off.

The suppression module should be selected and connected according to Finder's instructions. Its use does not remove the need to verify the electrical compatibility of the lamp and dimmer.
