Installation Instructions
UNIT DESCRIPTION
The Miro Decorator DCD270 Universal Dimmer provides dimming of various
120V lighting load types with a minimum load of 25W. When used in conjunction
with optional Miro DCD68 or MCD68 Multilocation Controllers, the DCD270
offers control of a dimming circuit from multiple locations.
Load Types
Do not mix different load types on the same dimmer.
Do not use with fl uorescent fi xtures other than those listed in the table below.
When more than one dimmer is installed in a multi-gang box, it is necessary to
reduce the maximum load on each dimmer as shown in the table below.
CAUTION
To reduce the risk of
overheating and possible
damage to other equipment, do not
install to control a receptacle, or a
motor-operated appliance.
CAUTION
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.

INSTALLATION
For ease of installation, manufacturer recommends use of a deep wall box.
1. Disconnect power to circuit by turning circuit breaker OFF before
installation.
2. Remove existing wall plate and switch.
3. Strip existing wires 1/2”.
4. Select your application to continue…
Single Location Application
5. Connect the LINE, NEUTRAL, and GROUND supply wires to the fl ying leads
on the DCD270 and connect the LOAD wire to the red fl ying lead on the
DCD270, as shown in Figure 1.

CAUTION
Turn the power off at the circuit breaker before installing the dimmer.
Two Location Application
Use with one Miro DCD68 or MCD68 Multilocation Controller.
Do Not Wire with Conventional Switches
As Part of a 3-Way or 4-Way Switching Circuit.
5. Install the DCD270 dimmer and the DCD68 (or MCD68) controller, following
the wiring diagram in Figure 2. The dimmer can go in either location. Use
a 3-wire and ground cable to wire between devices. (In existing 3-way
switched installations this wire is already in place.) The DCD68 and MCD68
require a ground. Be sure to verify the ground connection.

Finishing the Installation
6. Attach the wall plate.
7. Switch the circuit breaker ON.
8. Make sure the LED on the DCD270 dimmer is lit. There is no LED on
the DCD68 or MCD68 controller.
Fluorescent Setup
If the dimmer will operate 2-wire fl uorescent or compact fl uorescent loads,
a special confi guration step is required; if not, skip ahead to “Operation.”
1. Press and hold the top and bottom of the device paddle simultaneously until
the LED fl ashes yellow (about 2 seconds).
2. Release the top and bottom of the device paddle simultaneously then press the
top of the device paddle (
) until LED briefl y fl ashes red.
3. Press and hold the top and bottom of the device paddle simultaneously until
the LED changes to green (about 2 seconds).
4. To reconfi gure the dimmer to control non-fl uorescent loads, repeat the above
steps 1-3, but press the bottom of the device paddle (
) rather than in
step 2; the LED briefl y fl ashes green to confi rm the cancellation of
fl uorescent operation.
OPERATION
Tap once Fade the load to its last-used level
Tap twice Full bright
— — Press and hold Increase the present level
Tap once Fade the load to OFF
— — Press and hold Decrease the present level
Note: The dimmer may feel warm to the touch during normal operation.
When you see
in the instructions,
touch the top of the
device as directed.
When you see
in the instructions,
touch the bottom
of the device as
directed.
TROUBLESHOOTING
With one or more DCD68 or MCD68 Multilocation Controllers in the circuit, the
dimmer works, but the multilocation controllers don’t function.
LINE and LOAD connections might be reversed. Check to make
sure the connections are correctly terminated at the dimmer.
The 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. Remove power from
the circuit. Disconnect all traveler wires from the dimmer’s
Remote terminals. Restore power. If the dimmer now operates
the load properly, the problem is with the traveler wire. It may
be too long or may be shorted to another conductor.
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 identifi ed by its status LED.
(The DCD68 and MCD68 Multilocation Controllers do not have an LED and can not
operate this feature.)
To activate the feature from the dimmer:
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 they were
in immediately prior to loss of power.
CLEANING
Clean using a cloth dampened only with water and a little mild detergent.
Use of solvents or hydrocarbon-based cleaners may cause permanent damage.
