Maestro® Sensor Dimmer Features in Programming Mode (continued)
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.
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 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.
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.
