Features in Programming Mode

This Maestro Sensor Dimmer has features that allow you to customize the unit to achieve your individual needs. The following is an overview of these features

Timeout
Sensitivity
Auto-ON
Occupied Level

Timeout
The approximate time in minutes after which the lights will turn OFF after the last motion is detected. The default setting timeout is 5 minutes but can be adjusted to 1, 3, 15, or 30 minutes.

What Timeout Setting do I want?
Shorter timeouts are best in areas where occupants are generally moving around. Laundry rooms, foyers, kitchens, and closets are typically good applications for shorter timeouts. Longer timeouts are better for areas where occupants move less frequently, such as in an office. Using a timeout of 15 minutes or more may increase bulb life in fluorescent bulbs. Consider using a longer timeout if you are controlling a dimmable CFL.

Sensitivity
The setting determines how sensitive the PIR sensor will be. Lowering the sensitivity will cause the Maestro® Sensor Dimmer to respond only to larger movements.
- High Sensitivity: This is the most sensitive setting and will detect very slight motions. This is the recommended setting because it will work well for nearly all applications.
- Low Sensitivity: This is the least sensitive setting and can be used in areas of major or large motions.
- What Sensitivity Setting do I want?
  High sensitivity is typically the best setting. If the Maestro® Sensor Dimmer is turning on too often due to unintended interference from the environment (e.g., heating or cooling vents near the Maestro® Sensor Dimmer, moving draperies), low sensitivity may be selected.
- Auto-ON (Occupancy Version only)
  The automatic functionality of the Maestro® Sensor Dimmer can be adjusted to control how the lights respond upon initial occupancy. There are four available Auto‑ON settings: Enabled, Disabled, Ambient Light Detect (ALD), and OFF‑While‑Occupied (OWO). The default setting is Enabled.
- Auto-ON: Enabled: The lights will always turn ON when occupancy is detected.
  When the user manually turns OFF the light, the light will remain OFF for 25 seconds. After this time, the Maestro® Sensor Dimmer will turn lights ON if motion is detected.
- Auto-ON: Disabled: This setting converts the Maestro® Sensor Dimmer to Vacancy mode. The lights will not automatically turn ON but will still automatically turn OFF after vacancy. The lights must be manually turned ON by pressing the T button on the dimmer or switch.
- Auto-ON: Ambient Light Detect (ALD) Mode: The lights will turn ON when occupancy is detected and ambient light is too low. If lights turn ON when there is enough natural light, press the T button within 5 seconds of entering the room. If lights do not turn ON when there is not enough natural light, press the T button within 5 seconds of entering the room. Over time, this interaction will “teach” the Maestro® Sensor Dimmer your preferred setting.
- Auto-ON: OFF-While-Occupied (OWO) Mode: The lights will always turn ON when occupancy is detected. If lights are manually turned OFF, Maestro® Sensor Dimmer will keep lights OFF as long as room is occupied.
What Auto-ON Setting do I want?
- If you want the lights to automatically turn ON when someone enters the room, the Auto‑ON setting should remain enabled.
- If you want the lights to turn ON automatically when someone enters the room, but also want the dimmer to keep the lights OFF after it has been manually turned OFF, you should select OFF‑While‑Occupied mode.
- If you want the lights to turn ON only when the
- T button is pressed, choose Auto‑ON: Disabled. This is Vacancy mode, and the unit will turn OFF automatically only when occupancy is no longer detected. Bedrooms are a typical application where the Auto‑ON feature should be Disabled.
- If you want the lights to remain OFF when there is already enough ambient light in the room, Ambient Light Detect mode should be Enabled to maximize energy savings. The user(s), upon entering the room, must be prepared to correct the dimmer with the
- T button if the lights do not respond as expected.
Occupied Level
This setting determines how much light will be automatically turned ON when motion is detected.
Default Setting: 100%
- 100%: The lights will always turn on to 100% of the dimmable light level.
- 50%: The lights will always turn on to 50% of the dimmable light level.
- Preset: The lights will turn ON to the last level that was used on the Maestro® Sensor Dimmer. If you select a Locked Preset in Advanced Programming Mode, you will be able to lock this light level so that other adjustments will not change this preset
What Occupied Level Setting do I want?
- Preset mode allows for full customization of the preferred light level.
- 100% will ensure that the lights are turned on to the brightest level available upon entering a room.
- 50% is the default light level for manual operation of Maestro® products. To synchronize the default setting levels of all Maestro® products in the house, this is the best choice.
