Schneider Electric KNX. For heating, ventilation and air conditioning control. For controlling fan coil units with up to three speed levels and for controlling three-point motor drives (continuous/pulse width modulated) or two-point thermal drives. The actuator supports 2-pipe and 4-pipe systems. Two potential-free binary inputs for e.g. window contact and level contact for condensate collection containers. Connection of 1- to 3-speed fans. The buttons plus with room temperature controller can be used to control the fan coil actuator. With integrated bus coupler. For mounting on TH35 top hat rails in accordance with EN 60715. The bus connection is made via a bus connection terminal.
