Important Notes
Please read before installing.
1. Caution: To avoid overheating and possible damage to other equipment, do not use to control
receptacles, fluorescent lighting fixtures, motor-operated or transformer-supplied appliances, or
electronic low-voltage lighting fixtures.
2. Caution: Operating a dimmed magnetic low-voltage circuit with all lamps inoperative or removed
may result in current flow in excess of normal levels. To avoid possible transformer overheating or
failure, Lutron strongly recommends the following:
•Do not operate without operative lamps in place.
•Replace burned out lamps as soon as possible.
•To prevent premature failure due to overcurrent, use transformers with thermal protection or fused
primary transformer windings.
3. Install in accordance with all national and local electrical codes.
4. DO NOT use
Maestro® dimmers for compact fluorescent (Energy Saver) lamps.
5. When no “grounding means” exist within the wallbox then the NEC
® 2005, Article 404-9 allows a
dimmer without a grounding connection to be installed as a replacement, as long as a plastic, non-
combustible wallplate is used. For this type of installation, cap or remove the green ground wire on
the dimmer and use an appropriate wallplate such as Lutron’s
Claro® series wallplates.
6. Do not paint Dimmers or
Maestro Accessory Dimmers (MA-R, MSC-AD).
7.
Maestro IR® Dimmers are not compatible with standard 3-way/4-way switches. Use only with
Maestro Accessory Dimmers (MA-R, MSC-AD).
8.
Maestro Accessory Dimmers (MA-R, MSC-AD) can not be used individually and must be used in
conjunction with a
Maestro IR Dimmer in a 3-way/4-way application.
9. In any 3-way/4-way circuit use only one Dimmer with up to 9
Maestro Accessory Dimmers (MA-R,
MSC-AD).
10. Do not use where total lamp wattage is less than 60 W/VA or greater than wattage indicated on unit
label.
11. Operate between 0 °C (32 °F) and 40 °C (104 °F).
12. Dimmers may feel warm to the touch during normal operation.
13. Recommended wallbox depth is 2.5" (64 mm) minimum.
14. Maximum wire length between the Dimmer and the last
Maestro Accessory Dimmer (MA-R,
MSC-AD) is 250 feet (76 m).
15. Clean dimmers with a
soft damp cloth only . Do not use any chemical cleaners.
16. DO NOT use Incandescent/Halogen or Electronic Low-Voltage dimmers
for Magnetic Low-Voltage lighting.
Multigang Installations
When installing more than one control in the same wallbox, it may be necessary to remove all
inner side sections prior to wiring (see below). Using pliers, bend side sections up and down until
they break off. Repeat for each side section to be removed. Removal of Dimmer side sections
reduces maximum load capacity. Refer to the dimmer capacity chart below.

Multiple Gang Application
If multiple Maestro IR Dimmers are installed in the same location they will perform as below:
• Pressing the ON FULL button will cause each dimmer to fade to full brightness, regardless of
whether some are on and some are off.
• Pressing the OFF button will cause all dimmers to fade off.
• Pressing the BRIGHTEN or DIM buttons will change the light level on all units at the same rate
until the button is released or the lights are at min or max level. If any units are off when the
BRIGHTEN button is pressed they will turn on at the min brightness level.
• To save your favorite light level, adjust all the Maestro IR dimmers to the desired level then
press and hold the ONE-TOUCH button for about 3 seconds until the dimmer LED begins to
flash. Once your favorite light level is set, pressing the ONE-TOUCH button will cause each
dimmer to return to your favorite light level.
Point the transmitter at the
Maestro IR Dimmer(s), then use the buttons as outlined below.
ON FULL:
Tap once - lights brighten
smoothly to full intensity.
OFF:
Tap once: 3 second fade to off
Press and hold: 10–60 second
delayed fade to off.
This transmitter is compatable with
most learning remote controls.
Please see the learning remote
control manufacturer’s instructions
for programming information.
BRIGHTEN:
Press to brighten lights
DIM:
Press to dim lights.
ONE-TOUCH BUTTON:
Tap once to recall your favorite
light level.
To store your favorite level, press
and hold for about 3 seconds until
the dimmer LED begins to flash.
(“Off” is a valid preset level.)
Wiring.
• For installations involving more than one control in a wallbox, refer to Multigang
Installations before beginning.
• Use the screw or push-in terminals when making connections on the Dimmer or
Accessory Dimmer.
• Wire all controls before mounting.
