Theben 2/4-Channel Wireless Push-Button with Temperature Sensor KNX PS 1 RF (4941625)

In KNX installations where wiring is impractical or too costly, a wireless push-button with integrated temperature sensing provides a flexible control solution. The Theben 2/4-Channel Wireless Push-Button with Temperature Sensor KNX PS 1 RF (4941625) addresses this by offering battery-powered, surface-mounted control with KNX RF communication, eliminating the need for additional cabling.

Who is it for

This device is intended for KNX system integrators and building automation professionals who need a reliable, battery-operated input device for lighting, blinds, or scene control in residential and commercial buildings. It is especially useful in retrofit projects or areas where running new cables is difficult.
