Steinel PC4‑DALI‑2 wall control unit, white, button control, 43×15×50 mm, -20–50 °C

Steinel PC4‑DALI‑2 is a compact wall control unit in a white housing with button control, designed for integration into DALI2 lighting systems. With dimensions of 43×15×50 mm and an operating temperature range of -20 to 50 °C, the unit is intended for invisible under‑plaster installation behind standard push‑buttons in commercial and residential applications. The device requires no separate power supply because it is powered directly by the DALI bus and supports up to four conventional push‑buttons for switching, TouchDIM and basic scene recall when used with a DALI2 application controller.

Advantages

The PC4‑DALI‑2 enables seamless incorporation of existing push‑buttons into modern DALI2 lighting networks without visible changes to the wall design. Installation in a standard 55 mm flush box is concealed and does not need an extra power source. Functions of the connected push‑buttons can be freely assigned during commissioning via the Steinel app, and when paired with a DALI2 Application Controller the unit can call up programmed light scenes in addition to standard ON/OFF and dimming control.

• Under‑plaster installation behind existing wall push‑buttons in residential or commercial premises

How to use

Install the PC4‑DALI‑2 behind existing push‑buttons in a standard 55 mm flush box and connect it to the DALI bus. The unit receives power from the DALI line, so no separate power supply is required. During commissioning, use the Steinel app to assign functions to each connected push‑button and configure desired behaviors such as ON/OFF, TouchDIM or scene recall. If a DALI2 Application Controller is present, link the device to enable calling of programmed scenes.

Recommendations

For reliable operation, ensure the DALI bus wiring follows relevant installation standards and that the device is mounted in a protected location inside the flush box. Use the Steinel app and a compatible DALI2 Application Controller to configure and test button assignments and scene triggers before finalizing the installation.
