Glossary

Auto-On – A setting which allows the user to adjust the automatic functionality of the sensor. This will change how the dimmer responds upon initial occupancy of the room.
Auto-On: ALD – Setting where the dimmer turns on upon initial occupancy to the room only if there is NOT enough ambient light. The sensor will learn your preferred light level over time, through your interactions with the Tap button, and eventually will only turn the lights on, when there is not enough light in the room, and motion is detected. This setting is known as "Ambient Light Detect" mode.
Auto-On: Disabled – The dimmer will only turn on when the Tap button is pressed, but will still turn off automatically, when you vacate the room. This setting is also known as "Vacancy" mode.
Auto-On: Enabled – This is the default setting for your occupancy sensor. The sensor automatically turns on when you enter the room, and turns off when you vacate the room. This settiing is also known as "Occupancy" mode.
Auto-On: OWO – The sensor automatically turns on when you enter the room, and turns off when you vacate the room. If you manually turn the lights off, and remain in the room, this mode will allow the lights to remain off as long as you have not vacated the room. This setting is known as "Off-While-Occupied" mode.
Default Setting – Original preset programming options that the dimmer is programmed to upon initial use.
Factory Default – Original preset programming options set up as a starting point for users that wish to customize settings; also known as default setting.
FASS_™ – Tab at bottom of sensor dimmer, required to be pulled out for light bulb(s) replacement and entering all programming modes; also known as Air Gap.
Fast Blink – Indication of entering Programming Options, Indicator Lights (ILs) blink quickly at a rate of 8 flashes per second.
High-End Trim – Ability to change the highest achievable light level to which the dimmer can be adjusted.
Low-End Trim – Ability to change the lowest achievable light level to which the dimmer can be adjusted.
Load – The light bulb(s) that the dimmer is controlling.
Locked Preset – A programmable light level setting to which the dimmer will illuminate after a single Tap button press.
Normal Operation – Standard use of sensor dimmer (ON / OFF, Raise / Lower); Indicator Lights will not be blinking.
Occupied Level – A programmable setting that determines the light level your dimmer will turn on to, once occupancy has been detected.
Occupied Level: 100% – Your dimmer will turn all lights on to 100% of the dimmable light level when this is selected. This is the default mode for the dimmer.
Occupied Level: 50% – Your dimmer will turn all lights on to their half of their dimmable light level when this is selected.
Occupied Level: Preset – Your dimmer will turn all lights on to the last light level that has been selected by the user (1% - 100%). If you also lock your preset in the advanced programming options, your dimmer will turn ON to your Locked Preset light level.
Sensitivity – A programmable setting to adjust the level of sensitivity your sensor will have to detect motion.
Slow Blink – Indication of entering programming modes, Indicator Lights (ILs) blink slowly at a rate of 4 flashes per second.
Timeout – A programmable setting that determines how long the lights will remain on when motion has not been detected.
Unlocked Preset - A light level setting that allows the dimmer to turn ON to the last dimmed setting after a single Tap button press.

Maestro_® Occupancy Sensor C•L_® Dimmer Programming Mode

This Maestro_® dimmer sensor has many features to allow you to set the unit to meet your individual needs. The following is an overview of all the features of the product.

Explanation of Sensor Features

Timeout: The approximate time in minutes after which the lights will go out after the last motion is detected. The default timeout is 5 minutes but can be adjusted to 1, 3, 15, or 30 minutes. Typically, a shorter timeout should be used in a smaller room or a location where the duration of stay is short. Conversely, a longer timeout should be used in a larger room or a location where the duration of stay is long. The default timeout is 5 minutes.

What do I want?
The size of the room in which the unit is installed, position of the sensor in relation to activity and typical duration of stay will influence your desired timeout setting. The longer you plan on occupying a room the longer the value the timeout should be set.

Sensor Sensitivity: The sensitivity of the sensor can be adjusted based on the expected level of activity in the room. The sensitivity setting is high by default and will perform best for most applications. Rarely, if the sensor is placed near external sources such as heating and cooling vents, it may turn the lights on without occupancy. If this occurs, changing the setting to "low sensitivity" should resolve the problem. The default setting is "high sensitivity".

• High Sensitivity: This is the most sensitive setting and will detect very slight motions. This is the recommended setting, as it will work well for nearly all applications.
• Low Sensitivity: This is the least sensitive setting and is best used in areas of major or large motions.

What do I want?
The type of activity and amount of foot traffic will help dictate at which setting the sensor should be set. High sensitivity is recommended for spaces where the occupants will often be seated for long periods of time and performing fine motions such as turning a page. Low sensitivity is recommended for spaces that generally only experience large motions such as foot traffic.

Auto-On Feature (Occupancy Version only): The automatic functionality of the sensor 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) Mode, and Off While Occupied (OWO) Mode. The default setting is Enabled.

• Enabled: The lights will always turn on when occupancy is detected.
  Manual Off (Exit Time Delay): After the unit is manually turned off, the auto-on feature will be disabled for 25 seconds, even if motion is detected. This is to provide occupants time to exit larger rooms after manually turning the lights off. The unit can be manually turned on at any time. After 25 seconds, the unit will return to normal operation.
• Disabled: This setting converts the sensor 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 Tap button on the dimmer or switch.
• 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 Tap button within 5 seconds of entering the room. If lights do not turn on when there is not enough natural light, press Tap button within 5 seconds of entering the room. Over time, this interaction will "teach" the sensor your preferred setting.
• Off While Occupied (OWO) Mode: The lights will always turn on when occupancy is detected. If lights are manually turned off, sensor will keep lights off as long as room is occupied.

What 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 prefer that the lights only turn on when the Tap button is pressed, choose "Auto-On: Disabled". This is "Vacancy" mode, and the unit will only turn off automatically, 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) must be prepared to correct the dimmer with the Tap button if the lights do not respond as expected, upon entering the room.
• 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.

Occupied Level: The light level your sensor will turn on to when motion is detected is adjustable. There are three available settings for the light level.

• 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 always turn on to the last light level selected. If you have locked your preset light level in Advanced Programming Mode, the lights will come on to your locked preset level instead of the last level selected.

What do I want?

• To fully utilize the dimming capabilities, Preset mode allows for full customization of your preferred light level.
• 100% will ensure that the lights are turned on to the brightest available level upon entering a room. If you want the most light possible upon entering a room, this is the best choice.
• If you would like the default level to match the default level of other Maestro_® products in your house, 50% is the default Maestro_® light level for manual operation of Maestro_® products.

Programming Option 1: Preset Light Level

What Does It Do:
If it is preferred that the dimmer turns ON to the same light level every time you turn it ON (by pressing the Tap button), choose the Locked Preset. Double tapping the Tap button in Normal Operation Mode will always bring the light level to maximum intensity. If it is preferred that the dimmer turns ON (single tap) to the light level previously used, choose the Unlocked Preset setting.

SETTINGS
There are 2 settings in Option 1: Preset Light Level.
Locked Preset: When programmed for a Locked Preset, the dimmer will always turn ON to the predetermined "locked" level anytime the dimmer is turned ON with a single tap of the Tap button. If you want occupancy detection to turn your lights on to this locked preset, please set your "Occupied Level" to "Preset".
Unlocked Preset: When programmed for an Unlocked Preset, the dimmer will turn ON to the light level that it was adjusted to the previous time that the light was ON.
Note: Default Setting is Unlocked Preset.

DIRECTIONS
Selecting "Locked Preset"

1. While in Advanced Programming Mode (APM), Press the Raise / Lower button to select the first option, Programming Option 1: Preset Light Level. Once Indicator Light (IL1) is blinking, Press the Tap button. The IL will then switch to the current setting and begin blinking rapidly or turn OFF, indicating that the programming option has been entered.
2. When entering the Preset Light Level option for the first time upon installing, the default setting is "Unlocked."
   Note: Unlocked Preset is indicated by NO Indicator Lights turned ON while in Programming Option 1: Preset Light Level.
   Press the Raise / Lower button to choose desired light intensity. The light will become brighter or dim, reflecting the Locked Preset level as the feature is adjusted.

• The Manual Fade ON Times will only be seen when the lights are toggled from a Maestro_® Occupancy Sensor C•L_® Dimmer or a Companion Dimmer. While using a mechanical switch in a 3-way application, the lights will fade ON and OFF at an accelerated rate.
• If there is no button activity for 1 minute, the dimmer will automatically exit APM and return to Normal Operation.
• To save and exit immediately out of APM to Normal Operation, Press and Hold the Tap button until Indicator Lights stop blinking.

Programming Option 3: Manual Fade OFF Time

What Does It Do:
A slower light Manual Fade OFF Time is suggested for rooms where the user wishes to leave while the lights are still providing illumination. Please be aware that the light dimming may not be immediately noticeable for settings of 5 seconds or longer. This fade time adjustment only applies to manual actuation of the Tap button. All occupancy based fade times are fixed.

SETTINGS
Manual Fade OFF Time allows for control over how quickly the lights will fade down when the Dimmer is turned OFF. These settings include fade times from Maximum Light Output to OFF in as fast as 0.75 seconds and as slow as 15 seconds.

Symptom	Possible Cause	Solution
After installation or following power failure, the Lights will turn on suddenly after the Lights are manually turned OFF.	The Sensor takes up to 2 minutes to perform a calibration following a power cycle. If the lights are OFF and the calibration completes while the space is occupied, the Lights will turn ON	Wait at least 2 minutes for calibration to complete. Refer to the instructions.
		Change "Occupied Level" to "Preset". This will cause occupancy detection to turn your unit onto the last light level. It is less likely that you will notice this issue, if you have selected this setting.
After installation or after replacing the bulbs, the Lights may not turn ON when turning on the Lights manually or when the space is occupied.	The Low-End Trim setting may have to be adjusted.	Adjust the Low-End Trim from either the shortcut menu or from the APM menu. Refer to instructions to change custom settings.
	The bulbs may not be on the approved bulb list	Used bulbs are have been approved. Find the approved list for this product at www.lutron.com/dimcflled
After installation or after replacing the bulbs, the Lights may flash when turning on the Lights manually or when the space is occupied.	The Low-End Trim setting may have to be adjusted.	Adjust the Low-End Trim from either the shortcut menu or from the APM menu. Refer to instructions to change custom settings.
	The bulbs may not be on the approved bulb list	Used bulbs are have been approved. Find the approved list for this product at www.lutron.com/dimcflled
After installation or after replacing the bulbs, the LEDs may appear to cycle, making the Dimmer appear to reset. During this time, the Lights may not turn ON or the Lights may flash.	The Low-End Trim setting may have to be adjusted.	Adjust the Low-End Trim from the APM menu. Note: in this scenario the Low-End Trim cannot be adjusted from the shortcut menu. Refer to instructions to change custom settings.
	The bulbs may not be on the approved bulb list	Use bulbs that are on the approved list. Find the approved list for this product at www.lutron.com/dimcflled
3-way switch does not turn the lights ON.	Multi-location / 3-way wiring may be incorrect.	Refer to wiring diagrams in instructions.
	The multi-location mode is set for Companion Dimmer.	Change the accessory mode to 3-way switch. Refer to instructions to change custom settings.
	3-way switch may have a locator light.	Replace the 3-way switch with one that doesn't have a locator light.
After installation, the 3rd LED will start blinking, then the 2nd LED, etc.	A 3-way switch is wired to the blue wire but the accessory mode is set to Companion Dimmer. This causes the Dimmer to think the toggle button is being held and will activate the Delayed Fade To Off feature.	Change the accessory mode to 3-way switch. Refer to instructions to change custom settings.
Lights do not turn ON when space is occupied.	Sensor mode is set to Manual-On (Vacancy).	Refer to instructions to change custom settings.
	Sensor Mode is set to Auto-On Daylight Sensing (ALD) and the light level in the room is too bright.	Turn the lights on within 5 seconds upon entering the room to change the daylight threshold.
	Sensor does not have full view of room.	Move objects blocking the sensor's line-ofsight.
	Sensor mode is set to Off-While-Occupied (OWO) mode, and the unit was recently manually turned off.	Refer to instructions to change custom settings, exit room and wait for sensor to timeout, or manually turn light back on with Tap button.
	Multi-location / 3-way wiring may be incorrect.	Refer to wiring diagrams in instructions. Wiring of a 3-way mechanical switch with this product is different than traditional 3-way wiring.
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 the Instructions to change custom settings.
Lights turn OFF while the space is occupied	Sensor's timeout is too short for this application.	Increase timeout (i.e. 5 minutes to 30 minutes)
	Sensor does not have full view of room.	Move objects blocking the sensor's line-ofsight.
	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 1 minute, wait 1 minute 30 seconds to enter room again to verify lights don't turn back on.
	Sensor Mode may be set to something other than Manual-On (Vacancy).	Refer to instructions to change custom settings.
Turning the Lights ON with a 3-way switch caused my 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 LEDs are off.	If the Dimmer is connected to a generator, the Dimmer may go into 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 bulbs may not be on the approved bulb list	Use bulbs that are on the approved list. Find the approved list for this product at www.lutron.com/dimcflled
The sensor LED does not work.	Your sensor LED will not glow to acknowledge motion if the lights are off.	Make sure the load is ON, and wave to confirm that the sensor LED is operational.
