MTN645094 Schneider KNX Fan Coil Actuator REG-K 3-Speed Valve Control DIN Rail HVAC Room Unit Driver

The MTN645094 is a DIN-rail control instrument from the Schneider Electric SpaceLogic KNX catalogue, designed to provide precise, silent, and long-lasting actuation for lighting and shading networks. This module interprets bus telegrams into graduated control signals, enabling designers to create light scenes, ramp intensities, and protect expensive lamp equipment from harsh switching.

Within its compact thermoplastic housing, dedicated control electronics are paired with generously rated power stages that tolerate the inrush characteristics of switched-mode LED drivers and electronic transformers. Commissioning is performed through the standard ETS engineering tool, where each channel exposes comprehensive parameters including minimum brightness, soft-start time, and bus-failure response.

The front face maintains accessible programming push-button and manual override controls, allowing technicians to operate loads even before the bus network is active. Manufactured under ISO-certified processes with eco-conscious materials, the device carries full conformity documentation for simplified export to regulated markets across the Middle East, Europe, and Asia.

A purpose-built REG-K actuator designed to drive three-speed fan-coil units in hotel rooms and offices. It sequences fan speed with thermal valve commands to maintain stable and quiet room temperature, while its changeover input automatically adapts between heating and cooling seasons, reducing energy waste in year-round climates.
