Installation Instructions
The Miro™ MRD4 Wireless Universal Dimmer is mounted inside a wall box
and framed by an architectural screwless Miro wall plate (required and sold
Load Types
Use the Miro Wireless Universal Dimmer for these load types (at 120V):
• Incandescent & quartz halogen lamps (25-600W)
• Dimmable, 2-wire fluorescent and compact fluorescent fixtures, magnetic or
electronic low voltage, neon or cold cathode fixtures or diode equipped lamps
Do not mix different load types on the same dimmer.
Do not use with flourescent fixtures other than those listed
To reduce the risk of
overheating and possible
damage to other equipment,
do not install to control
a receptacle, or a motoroperated appliance.
Afin de réduire le risque de
surchauffe et la possibilité
d’endommager d’autres
matériels, ne pas installer
pour commander une prise,
ou un appareil à moteur.
When more than one dimmer is installed in a multi-gang box, it is necessary to
reduce the maximum load on each dimmer:
• For a dimmer in either end position of a multi-gang box, reduce its maximum
load by 100W.
• For a dimmer in a central position of a multi-gang box, reduce its maximum
load by 200W.
Miro Wireless
Miro wireless devices use radio signals to communicate with each other to
control lighting and other types of electric loads in selected areas. Miro wireless
devices use the 900MHz band for high-speed control communication. Using
the Watt Stopper’s own “frequency-agile” Top Dog™ technology, Miro wireless
devices avoid interference with other 900MHz devices, such as cordless phones
and baby monitors.
For ease of installation, use in a wall box that is at least 21/2” deep.
1. Disconnect power to circuit by turning circuit breaker OFF before installation.
Install only using a UL Listed Miro cover plate and subplate
assembly. If you do not have the proper Miro subplate for your
application, obtain one from any supplier of Miro devices.
Wall box
2. Remove existing cover plate and switch.
3. Temporarily attach the steel subplate for the
Miro cover plate to the wall box.
4. Pull the wiring through the new Miro subplate.
5. Strip existing wires 1/2”. If two wires will be connected
to the same terminal on a Miro device, both wires
must be the same gauge (12AWG or 14AWG).
6. Wire the LINE (black), NEUTRAL (white), LOAD and GND (green or bare)
supply wires to the correspondingly marked screw terminals, according to the
wiring diagram below.
7. Using the instructions provided with the Miro cover plate, attach the dimmer
to the metal subplate and to the electrical box, then attach the Miro cover.
8. Switch the circuit breaker back ON.
Failure to follow these
instructions may cause
personal injury or
equipment damage.
All Miro wireless devices installed in the same home must acquire the same
unique House ID before use. This process is known as house binding. Each Miro
wireless device is bound to all other Miro wireless devices in the house.
New Installation
1. With all devices installed and energized, make sure that every Miro wireless
device LED is yellow. If any LED is off, be sure the circuit breaker is on and the
device is correctly installed.

4. Return to the device used in step 2, which is still flashing yellow. Press
until the LED changes to solid green (about 2 seconds). All device LEDs in the
House change to solid green, indicating house binding is complete.
Adding a Device to an Existing Installation
If you’re adding or replacing a device in a Miro wireless installation that is already
operating, the new device must acquire the same House ID as the other Miro
wireless devices in the house. After the new device is powered up, the LED should
be solid yellow. This indicates that it has not yet acquired a House ID. To acquire
the House ID for the existing system:
1. Press on any previously bound device until the LED flashes yellow (about 2
2. Verify that the newly added device LED is flashing green, indicating that it has
acquired the House ID.
3. Return to the same previously bound device used in step 1 and press until
the LED changes to solid green (about 2 seconds). All device LEDs should now
be solid green.
Fluorescent Setup
If the dimmer will operate 2-wire fluorescent or compact fluorescent loads, a
special configuration step is required; if not, skip ahead to “Operation.”

Replacing Lamps
When a lamp must be replaced, use the Air Gap Isolation feature for safety. To
activate the feature:
Press FIRMLY, so that the paddle clicks and latches in. Make sure the status
LED is extinguished, indicating that it’s safe to relamp.
To release and return to normal operation, press .
Power Fail Memory
After a power failure, all Miro devices automatically return to the state that they
were in immediately prior to loss of power. All configuration and scene control
information is preserved.
Use a Wireless Miro universal dimmer in conjunction with one or more Miro
MRD8 Wireless Multilocation Controllers to control one lighting circuit from
multiple locations. Binding the MRD4 and MRD8 devices together in the same
Group enables them to work in exactly the same way, from any of the control
You can include other Miro wireless devices in the Group. Just remember that
all devices in the Group operate when one member operates. If you increase the
brightness on one circuit in the Group, all circuits will increase brightness.
Set the House ID (see Set House ID) before setting up Groups.
1. Go to any device that you want to include in the Group. Press . The device
LED flashes yellow, and all other devices in the House flash green.*
You now have 5 minutes to complete this process.
2. To include or exclude a device in the Group press on the device until the
LED changes color. Yellow flashing LED = Included in the Group
Green flashing LED = NOT included in the Group
If you get to a device and it is NOT flashing, the 5 minute binding process timer
may have expired. Go back to step 1 and repeat.
3. Return to the device used in step 1 and press to terminate Group binding.
All LEDs revert to solid green. Now, all the devices in the Group control their
load circuit in exactly the same manner.
* Adding a Dimmer to a Group in an Existing System
1. Go to a device that is in the Group where you want to add the dimmer. Press
. The device LED and all members of the Group flash yellow. The new dimmer
flashes green.
2. Press
on the new dimmer until it’s LED flashes yellow.
3. Return to the device used in step 1 and press
. All LEDs are solid green.
Scene Control
The Miro Wireless Universal Dimmer may be easily incorporated into room
and whole house preset scenes. The Miro Installation Guide provides more
information about configuring scenes and presets.
Instructions for installation and use are included with the relevant Miro wireless
room and whole house control devices. Application support information and the
Miro Installation Guide is available online.
Clean only using a cloth dampened with water and a little mild detergent.
Use of solvents or hydrocarbon-based cleaners may cause permanent damage.
During Set House ID, the LED is not flashing on some wireless Miro
• If LED is solid green before initiating house ID binding:
The device already has another house ID. Reset it to the factory default so
that it can be bound to the desired house ID. Resetting to factory defaults is
described in the “I need to start over” issue.
• If LED is solid yellow after initiating house ID binding:
The device may be out of range of the initiating device. Add a MRR2 Miro
Wireless Repeater to boost signal range.
I made a configuration mistake. I need to start over.
You can reset any Miro wireless device to factory default settings by pressing
and holding until the LED changes to solid yellow (approximately 10
seconds). During the process, the LED flashes yellow and when complete, it
changes to solid yellow. The device can then be reconfigured, exactly like any
new device (see the Set House ID section).
