ActronAir NEO Sense Zone Sensor in Black provides precise room temperature sensing for NEO Touch systems, with wireless RF communication, NFC connectivity, battery or wired power, and Over-The-Air updates to ensure accurate zone temperature data across Advance R32 and Classic Series 2 systems. On Advance R32, the NEO Sense delivers the same individual zone comfort control as the NEO Zone, accessible via the NEO Touch Master Controller or the NEO Connect app. Low voltage inputs only — connecting 240VAC will damage equipment and void your ActronAir warranty.
