The Schneider Electric M KNX heating actuator bus system can control one fan coil unit with up to three fan speed fans and two valves. It can also manage 2 or 4 coil fan spirals. The actuator is designed for DIN-rail TH35 installation in compliance with EN 60715, and features two floating binary inputs for window contact and condensate water container level contact. Each fan relay has an 8 A switching capacity, and the push-button plus room temperature control can be utilized to activate the fan spiral drive. The system includes an auxiliary relay with a switching power of 16 A for electric heating. The power supply is AC 230 V ±10 %, 50/60 Hz, and the device has a width of four modules or approximately 72 mm. The color of the device is light grey.
