iO HVAC Controls AC-SOS AC-SOS-LV Line Voltage Wireless A/C Shut-Off Switch AC-SOS-XX-LV

Description

The iO HVAC Controls AC-SOS-LV is a professional-grade wireless shutoff system designed to reduce unnecessary energy use in vacation rentals, condos, hotels, and light-commercial spaces. By detecting open doors and windows, the system automatically disables the mini-split outdoor unit when conditioned air is being wasted—saving energy, reducing equipment wear, and improving overall system efficiency.

The included solar-powered AC-SOS-TR door/window sensors communicate wirelessly with the outdoor receiver module. When a door or window is left open for more than 2 minutes, the system opens the OP contacts and shuts down the HVAC unit until the opening is closed again.

Built in a weatherproof enclosure and designed specifically for mini-split applications, the AC-SOS-LV provides reliable wireless control, long-life components, and easy installation for HVAC professionals.
