Io Hvac Controls AC-SOS-1-LV Wireless Ac Shut Off Switch

Product Description

The IO HVAC CONTROLS AC-SOS-1-LV is a wireless AC shut off switch designed to automatically disconnect power to a mini split system when a monitored door is opened. Operating at line voltage, this device provides a safety and energy-saving interlock between entry points and HVAC equipment. It is a single-door configuration, meaning it monitors one door contact and triggers the connected mini split to shut down when that door is left open. HVAC technicians and controls installers working on mini split installations in light commercial or residential settings are the primary installers of this unit.

This switch is suited for mini split applications in residential and light commercial environments where energy management and equipment protection are required. Typical installations include hotel rooms, server rooms, offices, and any conditioned space where a door-open condition should interrupt cooling or heating operation. The line voltage configuration means it wires directly into the power circuit of the mini split rather than through a low-voltage thermostat circuit, making it applicable where low-voltage control wiring is not present or practical.

Key Features

• Wireless door sensor communication eliminates the need for sensor signal wiring between the door and the controller
• Line voltage operation connects directly into the mini split power circuit
• Single-door configuration monitors one door contact point
• Designed specifically for mini split systems without low-voltage control inputs
• Compact enclosure measuring 14 x 14 x 6 inches for wall or surface mounting

Compatibility

Designed as an OEM-style wireless shut off control for line voltage mini split systems in single-door interlock applications.

Installation Notes

Installation should be performed by a licensed HVAC technician or licensed electrician familiar with line voltage wiring practices. Disconnect and lock out all power to the mini split circuit before beginning installation. Follow applicable NEC requirements for line voltage enclosures and wiring methods. Do not energize the unit until all wiring connections are secured and the enclosure is properly closed.
