• Automatic On/Off: The sensor will automatically turn lights on when you enter the room and off after you leave, based on programmed settings.
• Manual On/Off: Press the large tap switch at the top to manually turn lights on or off.
• Adjusting Light Level: Use the rocker switch on the right side to brighten or dim the lights to your desired level.
• Preset Light Level: The switch can be programmed to turn on to a specific preset light level.
• Service Switch: A small pull-out switch at the bottom can be used to completely cut power to the lights for maintenance or to keep them off while you are in the room.

7. Programming and Customization

The Maestro Motion Sensor Dimmer Switch offers several customizable settings to optimize its performance for your specific needs.

• Time-out Settings: Adjust how long the lights remain on after no motion is detected. Options typically include 1, 5, 15, or 30 minutes.
• Occupancy vs. Vacancy Mode:
  • Occupancy Mode (Default): Lights turn on automatically when motion is detected and turn off automatically when the room is vacant.
  • Vacancy Mode: Lights must be turned on manually (by pressing the tap switch) but will turn off automatically when the room is vacant. This mode is often used to comply with energy codes like Title 24.
• Ambient Light Detection: The sensor can be configured to prevent lights from turning on if there is already sufficient natural light in the room. The device learns your preferred light level over time.
• Sensor Sensitivity: Adjust the sensitivity of the motion sensor to detect fine movements or require more significant motion.
• Preset Light Level: Program the switch to always turn on to a specific dimmed level, regardless of the last manual adjustment.

Refer to the full user manual PDF for detailed instructions on how to access and change these programming settings.
