Lights turn back ON after
they are manually turned
OFF.
Sensor mode is set to Auto ON: Enabled
(Occupancy mode). The lights will continue to turn
back on 25 seconds after the lights are manually
turned OFF if the space is still occupied.
Change the Sensor mode to Auto ON: Disabled
(Vacancy mode) or OFF‑While‑Occupied (OWO)
mode. Refer to instructions to change custom
settings.
Lights turn OFF while the
space is still occupied.
Sensor’s timeout is too short for this application. Increase timeout (e.g., 5 minutes to 30 minutes).
Sensor does not have full view of room. Move objects blocking the sensor’s line-of-sight.
Sensor’s sensitivity is set too low. Change sensitivity to High.
Lights stay ON after space
is vacated.
Sensor’s timeout has not yet expired. Wait for the timeout to expire.
Motion is being detected from an external noise
source such as an HVAC vent.
Change the sensitivity to Low. Try to eliminate the
external noise source.
Lights turn ON when
walking past room.
Sensor coverage extends beyond room perimeter. Change sensitivity to Low. Block part of the lens.
Reflections off shiny objects can allow the sensor to
see outside the typical coverage.
Change sensitivity to Low. Block part of the lens.
Lights turn ON in Vacancy
mode.
Lights can turn ON in the 15 second “grace period”
following timeout.
If Timeout is set to 1 minute, wait for 1 minute 30
seconds before entering room again to verify that
lights don’t turn back ON.
Sensor mode may be set to something other than
Manual‑ON (Vacancy mode).
Refer to instructions to change custom settings.
Turning the lights ON with
a 3-way switch caused the
lights to flash.
If the sensor detects occupancy just prior to turning
the lights ON from the 3-way switch, the lights will
turn ON and the 3-way switch will turn the lights
OFF.
Set the Sensor mode to Auto ON: Disabled (Vacancy
mode). Refer to instructions to change custom
settings.
Following a power cycle,
the lights turn ON to the
full dim level, but the ILs
are OFF.
If the Maestro® Sensor Dimmer is connected to
a generator, the dimmer may go into a different
operating mode.
Press the Toggle button to resume Normal
Operation.
When turning the lights ON
to the maximum dim level,
the light dim level may go
to high-end and then drop
to a lower dim level.
The dimmer has an internal protection mechanism
that will reduce the dim level if the maximum level
causes the dimmer to function incorrectly.
Adjust the High‑End Trim from the APM menu. Refer
to instructions to change custom settings.

The sensor IL does not
work.
The sensor IL will not glow to acknowledge motion
