DESCRIPTION
The Miro MR2000 is a high capacity universal dimmer
designed for remote mounting in a 4” square box with a 1½”
extender. The dimmer is suitable for surface, semi-recess
or plenum mounting. Remote user control is available by
either binding the MR2000 to a wireless Miro control device
such as a wireless multilocation controller (see Figure 1)
or by wiring the MR2000 to a Miro multilocation controller
through a traveler wire (see Figure 2).
The MR2000 is wired directly to the load. It is a forward
phase control dimmer with a normally open air-gap relay
at the load output. It provides 120/277VAC, phase to neutral
input to the load.

Top Dog™ Wireless Communication
Wireless devices use radio signals to communicate with
each other to control lighting and other types of electric
loads in selected areas. These wireless devices use the
900MHz band for high-speed control communication. Using
“frequency-agile” Top Dog™ technology, these wireless
devices avoid interference with other 900MHz devices, such
as cordless phones and baby monitors.
Load Types
Use the Miro Universal Dimmer for these load types:
• Incandescent&quartzhalogenlamps.
• Dimmable,2-wirefluorescentandcompact
fluorescent, electronic low voltage, magnetic low
voltage, neon or cold cathode.
Do not mix different load types on the same dimmer.
Do not use with fluorescent lamps other than
those listed. See SPECIFICATIONS.
CAUTION
Do not install to control a receptacle,
or a motor-operated appliance.

BREAKER BEFORE INSTALLING THE DIMMER.
2. Strip existing wire ½” (12.7mm).
3. Wire the LINE (black), NEUTRAL (white) and LOAD lead
wires to the supply/load wires per Figure 2. If installing
in a grounded metal box, the unit will be grounded to
the electrical box. Otherwise, use the green ground
screw to connect to ground as shown in Figure 2. Use
#12AWG copper wire. Depending on the application and
the number of connections, more space may be needed.
If so, use an appropriate size box or box extension.
4. If the MR2000 will be controlled by a wired multilocation
controller (MCD68/DCD68) connect the yellow traveler
wire per the instructions provided with the controller.
If using the MR2000 in a Miro wireless network, the
yellow traveler wire is not used and must be capped.
5. Switch the circuit breaker back ON.
6. If the unit is to be controlled from a Miro wireless
device, refer to “SET HOUSE ID” on the next page.
INSTALLATION
The unit must be installed in compliance with the

FLUORESCENT SETUP
If the dimmer will operate 2-wire fluorescent or compact
fluorescent loads, a special configuration step is required.
1. Press and hold until the LED flashes yellow (about 2
seconds).
2. Press the top of the device paddle until the LED
briefly flashes red.
3. Press and hold until the LED changes to green (about
2 seconds.
4. To reconfigure the dimmer to control non-fluorescent
loads, repeat the above steps 1-3, but press the bottom
of the device paddle rather than in step 2; the LED
briefly flashes green to confirm the cancellation of
fluorescent operation.
SET HOUSE ID
(for wireless applications only)
All Miro wireless devices installed in the same system 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 in ON and the device is
correctly installed.
2. Press on any device paddle until the LED flashes
yellow (about 2 seconds). This indicates that it has
acquired a unique House ID.
3. Make sure that all other Miro wireless device LEDs are
flashing green, indicating that they have acquired the
same House ID.
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 are 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 seconds).
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.
ADVANCED OPERATION FOR WIRELESS
Application Assistance for wireless
The MR2000 can function as part of a network that may
contain a variety of wireless devices. The MR2000 may
be easily incorporated into room and whole house preset
scenes. Instructions for installation and use are included
with the relevant Miro wireless room and whole house
control devices.
The Miro Installation Guide provides more information
about configuring scenes and presets. Application support
information and the Miro Installation Guide is available at:
www.wattstopper.com.
Groups
Use a MR2000 dimmer in conjunction with one or more Miro
MRD8 Wireless Multilocation Controllers to control one
lighting circuit from multiple locations. Binding the MR2000
and MRD8/DRD8 devices together in the same Group
enables them to work in exactly the same way, from any of
the control locations.
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.
A device can only belong to one group at any time.
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
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
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.

Power Fail Memory
After a power failure, all wireless devices automatically
return to the state that they were in immediately prior
to loss of power. All configuration and scene control
information is preserved.
TROUBLESHOOTING FOR WIRELESS
During Set House ID, the LED is not flashing on some
wireless Miro devices.
• IfLEDissolidgreenbeforeinitiatinghouseIDbinding:
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.
• IfLEDissolidyellowafterinitiatinghouseIDbinding:
The device may be out of range of the initiating device.
Add a MRR2 Miro Wireless Repeater to boost signal
range.
