Wired Remote Controller Comparison: Backlit and Standard Models
Use this guide to compare the available functions of the backlit and standard wired remote controllers, including supported mixed-controller configurations.
Applicable Models:
Backlit Controller: UTY-RVNXM / UTY-RVNYN
Standard Wired Remote Controller: UTY-RNNXM / UTY-RNNYN
Mixed Configuration: UTY-RVNXM (Primary) + UTY-RNNXM (Secondary)
1. Overview
Both the backlit and standard wired remote controllers provide precise control over air conditioning operation and system monitoring.
However, the backlit model (UTY-RVNXM) offers enhanced visibility, user convenience, and expanded functionality, making it more suitable for advanced applications and multi-language environments.
2. Functional Comparison
Table key: Yes = supported; No = not available; Prohibited = configuration is not permitted.

3. Functional Notes
Group setting: Both controllers can be configured to operate as part of a remote controller group.
Auto-off timer: Valid only if air conditioning operation has been initiated via the controller’s On/Off button.
Timer increments:
Backlit model: Adjustable in 10-minute or 30-minute intervals.
Standard model: Adjustable only in 30-minute intervals.
4. Key Advantages of the Backlit Controller
Enhanced visibility in low-light environments.
Multi-language support for global installations.
Expanded scheduling options (8×2 programmable timers).
Password and mode restriction management for administrative control.
Advanced user feedback, including filter sign and summer time adjustments.
Selection guidance: Choose the backlit controller where visibility, multi-language support, expanded scheduling, password management or operation-mode restrictions are required.
