MCD68
UNIT DESCRIPTION
The Miro™ MCD68 Multilocation Controller is used in circuits with the Miro™
multilocation universal or multilocation incandescent dimmer to control lighting
loads from multiple locations. The MCD68 multilocation controller is mounted
inside a wall box and framed by an architectural screwless Miro wall plate
(required and sold separately).
Load Types
The MCD68 has no direct connection to the load. See the installation instructions
or specifications for the MCD26 Incandescent Dimmer, or the MCD267 Universal
Dimmer to determine compatibilty with those devices.
INSTALL IN COMPLIANCE WITH ALL APPLICABLE CODES AND
STANDARDS. Failure to follow these instructions may cause personal
injury or equipment damage.
DO NOT WIRE WITH CONVENTIONAL SWITCHES AS
PART OF a 3-WAY or 4-WAY SWITCHING CIRCUIT.
INSTALLATION
For ease of installation, use in a wall box that is at least 21/2” deep.
The dimmer may be in any position in the circuit. Use a 3-wire and ground cable
to wire between devices. (In existing 3-way switched installations this wire is
already in place.) The MCD68 requires a ground. Verify the ground connection.
1. Disconnect power to circuit by turning circuit breaker OFF before installation.
CAUTION
TURN THE POWER OFF AT THE CIRCUIT BREAKER
BEFORE INSTALLING THE DEVICE.
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.
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. ...select your application to continue...

7. Install the MCD267 dimmer and the MCD68 controller, following the wiring
diagram in Figure 1 for two locations, or Figure 2 for three or more locations.

7. Install the MCD26 dimmer and the MCD68 controller, following the wiring
diagram in Figure 3 for two locations, or Figure 4 for three or more locations.
Finishing the installation
8. Using the instructions provided with the Miro cover plates, attach each of
the Miro devices to their associated metal subplate and to the wall box, then
attach the Miro cover.
9. Switch the circuit breaker ON.
10.Make sure the LED on the dimmer is lit. There is no LED on the MCD68
controller.

Replacing Lamps
When a lamp must be replaced, use the Air Gap Isolation feature for safety. This
feature is only available at the dimmer, which can be identified by its status LED.
(The MCD68 Multilocation Controllers do not have an LED and can not operate
this feature.)
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.
CLEANING
Clean only using a cloth dampened with water and a little mild detergent.
Use of solvents or hydrocarbon-based cleaners may cause permanent damage.
TROUBLESHOOTING
In a multilocation circuit with one or more MCD68 multilocation
controllers, the dimmer works, but the multilocation controllers
don’t function.
This condition would exist if the LINE and LOAD connections are reversed.
Check to make sure the connections are correctly terminated at the dimmer.
The MCD68 Multilocation Controllers require a ground connection. Check to
make sure the ground wires are securely connected.
The light level changes without pressing any switches, or the
dimmer does not respond when I press its switch.
There may be a problem with the traveler wire.
1. Remove power from the circuit.
2. Disconnect all traveler wires from the dimmer’s Remote terminals.
3. Restore power.
If the dimmer now operates the load properly, the problem is with the traveler
wire. It may be too long or it may be shorted to another conductor.
