Leviton 3-Zone IRC Dimming Room Control Kit

Leviton 3-Zone IRC Dimming Room Control Kit

The Leviton IRC Dimming Room Control Kit is a complete low-voltage lighting control solution built around a 3-Zone Room Controller with (3) 0-10V outputs and (1) 120/277V relay. The kit pairs the controller with an M/T Occupancy Sensor (OSC20-M0W), a 4 Button Switch (RLVSW-4LW), and a Photocell (ODC0P-00W) to deliver automated, code-compliant dimming and lighting control for commercial spaces. Designed for 50/60Hz operation and engineered to meet Title 24 and ASHRAE 90.1 requirements, this kit gives contractors and facility managers an integrated, ready-to-install control package for zoned lighting applications.

Key Features

• 3-Zone Room Controller: Includes (3) 0-10V dimming outputs for independent zone-level lighting control.
• Integrated Relay: Built-in 120/277V relay for direct control of lighting loads (347V relay version also available).
• Occupancy Sensing: M/T (Multi-Technology) Occupancy Sensor (OSC20-M0W) automatically detects room occupancy to reduce wasted energy.
• 4 Button Switch: RLVSW-4LW low-voltage switch provides manual override and scene control at the wall.
• Daylight Harvesting: ODC0P-00W Photocell enables automatic daylight-responsive dimming.
• Universal Frequency: Rated for 50/60Hz operation for broad compatibility.
• Available Voltage Options: 120/277V or 347V relay configurations to match project requirements.
