The Lutron MS-Z101-WH Maestro® 0–10V Dimmer Sensor is a wall-mounted lighting control device that combines a dimmer with an occupancy/vacancy sensor for fluorescent and LED driver loads. Designed for commercial and residential applications, it provides automatic light control with manual dimming and multi-location capability.
- Maestro® MS-Z101-WH Multi-Location Dimmer Sensor Switch With Occupancy/Vacancy Sensor, 120 to 277 VAC, Wall Mount
Integrated 0–10V Dimmer + Occupancy/Vacancy Sensor → Combined control in one device
Controls lighting levels while automatically turning lights on/off based on room occupancy.
Passive Infrared (PIR) Detection with XCT Technology → Accurate motion sensing
Detects heat-based movement to identify occupancy, improving reliability in real-world conditions.
Large Coverage Area (Up to 900 sq ft) → Fewer devices required per space
Covers up to 30 ft × 30 ft for major motion and 20 ft × 20 ft for minor motion.
Adjustable Timeout and Sensitivity → Customizable operation per space
Timeout (1–30 minutes) and sensitivity (High to Min) can be tuned to reduce false triggers and optimize performance.
Ambient Light Detection (ALD) → Prevents unnecessary lighting
Automatically keeps lights off when sufficient natural light is present.
Multi-Location / 3-Way Capability → Flexible installation layouts
Works with mechanical switches or compatible accessory switches for control from multiple locations.
Selectable Dimming Curve (Linear / Square Law) → Optimized dimming performance
Matches driver response characteristics for consistent light control.
Miswire & Incompatible Load Alerts → Simplified troubleshooting
Provides visual indication of wiring or load issues while maintaining switching functionality.
High-End & Low-End Trim Settings → Stable dimming range
Prevents flickering and limits maximum output for energy control.

What lighting types are supported by the Lutron MS-Z101-WH?
The Lutron MS-Z101-WH is designed for 0–10V electronic fluorescent ballasts and LED drivers that meet current source requirements.
What is the detection range of this dimmer sensor?
It provides up to 900 sq ft major motion coverage and 400 sq ft minor motion coverage with a 180° field of view.
Can this device be used in multi-location setups?
Yes, it supports single-pole, 3-way, and multi-location installations with compatible accessory switches or a rewired mechanical switch.
Does the sensor adjust based on ambient light levels?
Yes, it includes Ambient Light Detection (ALD), which prevents lights from turning on when sufficient natural light is present.
What customization options are available for operation?
Users can adjust timeout duration, sensitivity, dimming levels, auto-on behavior, and fade rates, allowing configuration for different room requirements.
