Designed for both retrofit and new installations, the FX-Air1™ installs discreetly inside virtually any wall-mounted evaporator, providing a simple, elegant and cost-effective way to add intelligent climate control to every room in the home. Featuring FREE* native CRESTRON HOME® IR drivers, installers can deploy one FX-Air1™ per indoor unit, creating a fully integrated multi-room HVAC solution for a fraction of the cost of traditional wired systems. Learn Once. Control Everything.™ At the heart of the FX-Air1™ is Flex's exclusive Learn & Go™ technology, powered by the intelligent Protocol Engine™. Instead of learning every infrared command individually, installers capture just one command from the original air conditioner remote. The Protocol Engine™ automatically identifies the IR protocol and generates the remaining commands, reducing commissioning from dozens of learned codes to a simple two-step process.
