Overview

The Vimar VM03955 is a 4-button EnOcean RF wall control that transmits at 868.3 MHz and powers itself through an electrodynamic generator, so it does not need batteries or a wired supply. It is a 2-module unit that is completed with Vimar Eikon 20506 or 20506.2, Arké 19506 or 19506.2, or Plana 14506 or 14506.2 button sets. With IP40 protection, it belongs in dry, sheltered interior locations.

On a boat, this is a clean way to add a switch point for cabin lights, courtesy lighting, or other loads that are switched through a compatible EnOcean receiver or actuator. It communicates using the EnOcean Equipment Profile (EEP) F6 02 01, so the receiving device needs to support that profile. Range can reach up to 70 m in open field, but it drops when the signal has to pass through onboard structure and metalwork, so placement and a quick signal check matter.

Key features

• Energy harvesting operation with a built-in electrodynamic generator, with no batteries to replace
• EnOcean RF transmitter at 868.3 MHz, using EEP F6 02 01 for compatibility with supported EnOcean receivers
• Four-button flat control in a 2-module format, completed with Eikon, Arké, or Plana dedicated button sets
• Up to 70 m range in open field, with reduced performance through metal and dense construction
• Flush or surface mounting supported, with IP40 protection suited to indoor, sheltered spaces
• Operating temperature range of -5 to +45 °C for indoor use

Installation and setup

The device can be installed flush or surface mounted. For surface mounting, it uses a dedicated mounting frame (21507, 20507, 19507, 20607, or 14607) and is commonly fitted on materials such as wood and masonry. The front button set is selected to match the Vimar series you are using (Eikon, Arké, or Plana) and clips onto the unit to create the finished 4-button control.

When a button is pressed, a mechanical click is required for the radio command to transmit. Before finalizing the mounting location on board, it is worth checking the radio link quality with the receiving actuator or gateway, especially if the bulkhead area includes metal panels or nearby equipment.

Compatibility and system integration

This is an EnOcean radio transmitter, so it works with EnOcean receivers and actuators that accept EEP F6 02 01 (for example, compatible EnOcean relay actuators). It does not switch a load directly, and it is not a wired bus interface, so the actual power switching is handled by the receiving device you pair it with.

The RF band is 868.3 MHz, which is typically used for EnOcean in Europe. If your vessel is being outfitted for a different regulatory region, confirm that 868 MHz devices are appropriate for the installation location and the rest of the EnOcean equipment on board.

Use cases on board

This control suits refits where you want an extra switching point without pulling new control wiring through headliners or joinery. It is commonly used for lighting scenes, berth and cabin switching, or adding a second control location near a companionway or nav station, as long as the EnOcean receiver is within reliable radio range.

It is a good match for owners who want battery-free wall controls for interior spaces and who already have, or are adding, EnOcean actuators or a gateway to handle the actual switching.

Placement and environment

With IP40 protection and an indoor operating range, plan to mount it in protected areas such as cabins, saloon spaces, wheelhouse interiors, or other dry locations. Avoid exposed cockpit surfaces and anywhere that sees washdowns, spray, or persistent condensation.
