Io Hvac Controls AC-SOS-4-LV Wireless Ac Shut Off Switch

Product Description

The IO HVAC CONTROLS AC-SOS-4-LV is a wireless air conditioning shut off switch designed for line voltage applications in mini split systems. It operates as a safety disconnect device, cutting power to the AC unit when triggered by door or window contacts across up to four zones. The unit is suited for commercial and residential installations where energy management and occupancy-based control are required. Licensed HVAC technicians and controls specialists are the primary installers. The enclosure measures 14 inches wide by 14 inches tall by 6 inches deep and weighs 3.38 pounds, making it a wall-mountable panel suitable for standard electrical rough-in locations.

The AC-SOS-4-LV is applied in mini split installations where line voltage shut off is needed across multiple entry points. A common scenario is a hotel, multi-room residential addition, or light commercial space where the HVAC system should de-energize when doors or windows are opened. The four-door input capacity allows a single unit to monitor up to four contacts simultaneously, reducing the need for multiple controllers in multi-opening layouts. This makes it a practical fit for small commercial suites, server rooms, or residential additions with several exterior access points.

Installation Notes

Installation should be performed by a licensed HVAC technician or licensed electrician familiar with line voltage wiring and local codes, including applicable NEC requirements. Disconnect and lock out all power to the mini split system before wiring the controller. Mount the enclosure securely to a wall surface in a location that allows clear wireless signal reception to all door or window contact transmitters. Do not apply power to the unit until all wiring connections are complete and inspected per local authority having jurisdiction.
