ABOUT BRAND

Precision Analog Tactility, Surface-Mount Versatility & Low-Profile Wireless Dimming

Product Description

The MRYT-1805 Rotary Dimmer Wall Transmitter provides precise wireless lighting control through an elegant rotary knob combined with convenient push-button operation. Using 433.92MHz RF wireless communication, it communicates with compatible ARC RF433 dimmer receivers to deliver smooth brightness adjustment and reliable ON/OFF switching without requiring electrical wiring.

Installation is fast and flexible using either the supplied screws or double-sided adhesive tape, allowing the transmitter to be mounted on a standard electrical wall box or directly onto a flat wall surface. Powered by a CR2032 lithium battery, the transmitter eliminates the need for mains power while maintaining dependable long-term operation.

The unit supports two selectable dimming modes: step dimming for universal compatibility with dimmable receivers, and continuous dimming for compatible M-series receivers. Its clean, minimalist design makes it suitable for homes, hotels, offices and commercial smart lighting installations.
