Lutron MS-Z101-WH
Lutron Maestro 0-10-Volt Dimmer Sensor Switch MS-Z101-WH User Manual
Model: MS-Z101-WH | Brand: Lutron
1. Introduction
This manual provides detailed instructions for the installation, operation, and programming of your Lutron Maestro 0-10-Volt Dimmer Sensor Switch (Model MS-Z101-WH). This device combines a dimmer with advanced motion sensing technology to automatically control lighting in a space. It is designed for use with 0-10V LED drivers and fluorescent ballasts.
The Maestro sensor features passive infrared (PIR) detection with a 180° field of view, covering up to 900 sq. ft. for major motion and 400 sq. ft. for minor motion. Lutron's Cross Correlation Technology (XCT) enhances detection of fine movements, preventing lights from turning off unexpectedly.

5. Operating Instructions
The Maestro dimmer sensor switch offers both automatic and manual control of your lighting.

Figure 3: Key components and dimensions of the dimmer sensor switch.
5.1 Automatic Operation (Occupancy/Vacancy Sensing)
- Occupancy Mode: The sensor automatically turns lights ON when you enter the room and OFF when you leave. This is the default mode.
- Vacancy Mode: Lights must be manually turned ON, but will automatically turn OFF when the room is vacated. This mode helps meet Title 24 requirements.
The sensor's advanced XCT technology detects both major and fine motion, ensuring lights remain on while the room is occupied.

5.2 Manual Control
- Tap Switch: Press the large paddle at the top to manually turn lights ON or OFF.
- Rocker Switch: Use the small rocker switch on the side to manually adjust the light level up or down.
- Preset Level: The dimmer can be programmed to turn lights on to a specific preset brightness level automatically.
6. Programming Features
The Maestro dimmer sensor switch offers several customizable settings to optimize performance for your specific needs. Refer to the detailed programming guide included with your product for step-by-step instructions.
- Timeout: Adjust how long the lights remain on after the room is vacated. Options typically include 1, 5, 15, or 30 minutes.
- Low-End Trim: Set the minimum light level to ensure stable dimming performance with your specific light fixtures.
- Sensor Sensitivity: Adjust the sensor's responsiveness to motion. Higher sensitivity detects smaller movements, while lower sensitivity reduces false triggers.
- Occupancy/Vacancy Mode: Switch between automatic ON (occupancy) and manual ON (vacancy) modes.
- Ambient Light Detection: The sensor can detect existing daylight and keep lights off if the room is already sufficiently bright, further saving energy.
