Schneider Electric SpaceLogic KNX Fan Coil Actuator REG-K (MTN645094)

Schneider Electric MTN645094 is a SpaceLogic KNX fan coil actuator in DIN-rail housing that regulates heating and cooling in two- and four-pipe fan-coil systems. It provides three switching outputs at 16 A and two at 0.5 A for valve control, plus two binary SELV inputs, and operates on the KNX bus with local manual override. The four-module light-grey enclosure clips onto a standard 35 mm rail with IP20 protection. Typical application is room climate control in offices and hotel rooms using fan-coil units.
