LG Air Conditioner Cassette Remote Controller

The LG Cassette Air Conditioner Wired Wall Remote Controller (Part Number: AKB74855302) is an authentic original equipment manufacturer (OEM) replacement central control interface designed for LG ceiling cassette, ducted, and light commercial HVAC systems. Connected directly to the indoor unit control PCB via a low-voltage communication harness, this wall-mounted digital thermostat provides comprehensive control over room temperature adjustments, operating modes (Cool, Heat, Fan, Auto, Dehumidification), multi-speed fan control, scheduling timers, and vane direction. Its modern square form factor (121 x 121 x 16 mm) and minimalist button layout make it ideal for offices, retail spaces, and modern residences.

Key Features

• High-Visibility Digital Display: Large LCD screen clearly displays current room temperature, target setpoints, active operational modes, diagnostic codes, and timer configurations.

• Intuitive 5-Way Keypad Interface: Features a centralized navigational D-pad (Up/Down/Left/Right/OK), Return key, and Power button for fast menu navigation and adjustments.

• Pre-Wired 97 cm Communication Harness: Includes an integrated multi-core low-voltage cable with a factory polarized terminal block for direct plug-and-play PCB connection.

• Clean Flush-Mount Wall Profile: Slim 121 x 121 mm square casing mounts seamlessly onto standard electrical junction boxes or drywall surfaces.

Benefits

• Solves unresponsive wall thermostats, damaged LCD screens, faulty navigational buttons, or severed PCB communication lines.

• Eliminates intermittent infrared signal dropouts and dead batteries by providing a reliable direct hardwired connection.

• Direct OEM replacement guarantees factory communication protocols, voltage compatibility, and precise wall-mount fitment.
