Io Hvac Controls AC-SOS-3-LV Wireless Ac Shut Off Switch

Product Description

The IO HVAC CONTROLS AC-SOS-3-LV is a wireless air conditioning shut off switch designed for line voltage applications on mini split systems. It provides a 3-door configuration that enables remote disconnection of power to the indoor unit when triggered by a connected contact closure, such as a door or window sensor. HVAC technicians and installers use this device to meet energy code requirements or occupant comfort controls in residential and light commercial settings. The unit measures 14 x 14 x 6 inches and weighs 3.28 pounds, making it a compact but complete enclosure-style solution for line voltage mini split installations.

The AC-SOS-3-LV is suited for mini split systems operating on line voltage circuits where automatic shut off is required upon door or window opening. It is commonly installed in hotel rooms, multi-family units, offices, and other spaces where energy management dictates that cooling stops when an exterior door or window is opened. The 3-door input configuration allows simultaneous monitoring of up to three contact points before triggering the shut off relay, giving installers flexibility in multi-opening room layouts.
