Mini dimmer DIMAX 540 APP B: The world's smallest dimmer now it's really smart
Retrofit without neutral conductor but with app!
The new DIMAX 540 APP B mini dimmer for flush mounting from Theben brings more comfort and intelligence to older buildings – and in the smallest of spaces. It is based on the proven DIMAX 540 plus B, but significantly expands its range of functions: controllable via app, Bluetooth Mesh-enabled and with scene and astro functions – the problem solver for millions of old buildings is now even smarter.
Measuring just 32.5 x 26.6 x 9.6 mm, the new flush-mounted mini dimmer is hardly bigger than a 2-euro coin.
Programming and operation are conveniently carried out via app using Bluetooth.

-
App control: Convenient programming and operation via smartphone
-
Bluetooth Mesh: Devices can be networked with each other for greater range, reliability, and switchable scenes
-
Scenes and astro programs: Light can be customized even more
-
Advanced comfort functions: Night switch-off with astro function, power consumption display, date control
Smart and secure – even in small spaces
Measuring just 32.5 x 26.6 x 9.6 mm, the new flush-mounted mini dimmer is hardly bigger than a 2-euro coin. The DIMAX 540 APP B is also suitable for two-way circuits with larger distances and multiple push buttons for cable lengths of up to 100 m. Thanks to its memory function, minimum brightness, overcurrent and temperature cut-off, it offers not only smart but also safe lighting control – ideal for living rooms, hallways or the modernization of entire buildings. Compared to other solutions, the mini dimmer is cost-efficient and flexible to use with little effort.
