3c – Three or More-Location Control
Once the Dimmer/Switch learns the Wireless Controller, the Dimmer/Switch’s LED(s)
and load will flash 3 times and it will exit Set-Up mode.
Repeat steps 1 —3 to set up multiple Wireless Controllers to a single Dimmer or Switch.
Repeat steps 1 —3 to set up a single Wireless Controller to multiple Dimmers/Switches.
Important:
Set up Wireless Controller to a Dimmer/Switch before use.
Press and hold the Dimmer/Switch’s Tap Button (Figure 1) for approximately 6 seconds.
Once the LED(s) start to blink slowly,
release the Tap Button.
Press and hold the Off Button on the Wireless Controller (Figure 2) for approximately
6 seconds.
Removing Wireless Controller
To remove a previously set up Wireless Controller tap the Wireless Controller’s On button
three times, on the third tap hold for 3 seconds and then tap 3 more times. This will
remove all Dimmers/Switches it was previously setup with.
Pressing the Preset Button will cause each Dimmer/Switch to return to it’s favorite light setting.
To save a favorite light setting, adjust all the Dimmers/Switches controlled by a Wireless
Controller to the desired light setting. Then press and hold the Preset Button on the Wireless
Controller for approximately 6 seconds until all LEDs on the Dimmers/Switches stop blinking.

1. Install in accordance with all national and local electrical codes.
2. When no “grounding means” exist within the wallbox, then the NEC
®
2008, Article 404.9
allows a Dimmer without a grounding connection to be installed as a replacement, as long as
a plastic, noncombustible wallplate is used. For this type of installation, twist a wire connector
onto the green ground wire or remove the green ground wire on the Dimmer and use an ap-
pro pri ate wallplate such as Claro
®
or Satin Colors
®
series wallplates by Lutron
®
.
3. Do not paint the Dimmers or the Companion Dimmers.
4. The Dimmers are not compatible with standard 3-way or 4-way switches. Use only with
Lutron
Companion Dimmers.
5. In any 3-way/4-way circuit use only one Dimmer with up to 9 Companion Dimmers.
6. Do not use where the total load is greater than the rating indicated in the Derating Chart below.
7. Do not use where total load is less than 50 W / VA.
8. Operate between 32 °F (0 °C) and 104 °F (40 °C).
9. For indoor use only.
10. It is normal for the Dimmers to feel warm to the touch during operation.
11. Recommended minimum wallbox depth is 2.5 in (64 mm).
12. Maximum wire length between the Dimmers and the furthest Companion Dimmer is 250 ft (76 m).
13. Clean with a
soft damp cloth only
.
Do not use any chemical cleaners.
14.
DO NOT
mix MRF
and MRF2
lighting controls products within the same system. Products are
NOT compatible
, contact
Lutron Technical Support Center.
15. Controls must be mounted vertically. See stamp on control for correct positioning.
16.
DO NOT
wire while circuit breaker is on. Permanent damage to the Dimmer may result.
17.
DO NOT
use Incandescent / Halogen or Electronic Low-voltage Dimmers for Magnetic Low-
voltage lighting.
18. Up to 10
Maestro Wireless
controls can be configured to work together.
Multigang Installations
When installing more than one control in the same wallbox, the maximum load capacity is reduced.
No derating is required for Companion Dimmers. Refer to the Derating Chart below.

*The maximum lamp wattage is determined by the efficiency of the transformer, with 70%–85% as typical. For actual
transformer efficiency, contact either the fixture or transformer manufacturer. The total VA rating of the transformer(s)
shall not exceed the VA rating of the dimmer.
Multiple Dimmer Applications
If multiple
Maestro
Wireless
Dimmers are set up to the same Wireless Controller, they will perform
as follows:
Pressing the On Button on the Wireless Dimmers
•
Controller will cause all Dimmers to turn on fully.
Pressing the Off Button on the Wireless Controller will
•
cause all Dimmers to turn off completely.
Pressing the Raise Button on a Wireless Controller will
•
cause the Dimmer to turn on and gradually
increase the light level.
Pressing the Lower Button on a Wireless Controller will
•
cause the Dimmer to gradually decrease
light level.
Tap Button Options.
Tap once when
•
the Dimmer is off:
Lights brighten smoothly
to preset intensity.
Tap once when the
•
Dimmer is on:
Lights
dim smoothly to off.
Tap twice quickly:
•
Lights brighten rapidly
to full intensity.
Press and hold when
•
the Dimmer is on:
Each time the Dimmer is
turned off, delayed fade
to OFF can be activated.
As the Tap Button is
held, the current LED
will begin to flash. This
flashing LED represents
20 seconds of delay
before the lights fade
to OFF.
Dimming Rocker
Press to brighten.
Press to dim.

Important Notice:
To replace the bulb, power may be
conveniently removed by pulling the

For any procedure other than
routine bulb replacement, power
must be disconnected at the

Installation
Turning Power OFF
Turn power OFF at circuit break er (or remove fuse).
Disconnecting the Switch Wires.
Important Note:
The wall switch may have two wires attached to the same screw
(see illustrations below for examples). Tape these two wires together before
disconnecting. When rewiring, connect wires to the Dimmer the same way they
were connected to the switch.
Wiring
When making wire connections, follow the recommended strip lengths and
combinations for the supplied wire connector.
Note
: All wire connectors provided are suitable for
copper wire only.
For aluminum
wire, consult an electrician.
Removing
Wallplate and Switch
Remove the wallplate and
switch mounting screws.
Carefully remove the switch from the wall
(do not remove the wires).

One switch controlling a light fixture:
This switch will be a single-pole. The switch will
have insulated wires connected to two screws of the
same color plus a green ground screw.
Two switches controlling a light fixture:
Both switches will be 3-way. Each switch will
have insulated wires connected to three screws
plus a green ground screw. One of these wires is
connected to a screw of a different color (not green)
or labeled COMMON. Tag this wire on both switches
to identify when rewiring.
Three or more switches controlling a light fixture:
Two switches will be 3-way and any others will be
4-way. Tag the two 3-way switches as in the Two-
Location diagram above. The 4-way switch will
have insulated wires connected to four screws plus
a green ground screw. Tag the two same-color
insulated wires that are connected to opposite
colored screws. Follow this procedure for each
4-way switch.
