ActronAir NEO Zone Controller mounts inside the zone and provides individual zone temperature control, zone ON/OFF, and system ON/OFF from within the room, operating on battery or wired power with wireless RF communication to the NEO Touch Master Controller. On Advance R32 systems it delivers full individual temperature control per zone — on Classic Series 2 it provides zone on/off switching and a timer. Low voltage inputs only — connecting 240VAC will damage equipment and void your ActronAir warranty.
