The Narrow Master Blinds Switch iO SIMON 270 allows the control of 1 or several shutter switches. Thanks to this master we get to control from another point our shutter or awning motor, just as you can from the Simon iO App. It is compatible only with the minimal aesthetic frames of SIMON 270, in addition to needing the base frame, which must be purchased separately to have the complete mechanism. For its connection you only need direct power supply, because the pairing is done through the App. Reference: 21001133
