The Genuine ActronAir LR7-1W is a slimline LCD wall controller for ActronAir ducted split systems, delivering 8-zone climate control, 7-day programmable scheduling, NFC configuration, and self-diagnostic fault code display — without it, zone-level control is lost and the system cannot respond to individual room demands. A failed or incompatible controller severs the communication link between occupant and system, disabling zone tracking, hot start protection, and filter change monitoring entirely. Fit the 100% Genuine ActronAir LR7-1W to guarantee factory-certified system compatibility, protect your ActronAir manufacturer warranty, and maintain the full zoned performance that non-genuine substitutes cannot reliably deliver. Low voltage inputs only — connecting 240VAC will damage equipment and void your ActronAir warranty.
