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 & quartz halogen lamps.
• Dimmable, 2-wire fluorescent and compact
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.
ENVIRONMENT AND ORIENTATION
This product is designed for indoor use only where the
ambient temperature in the unit’s vicinity does not exceed
104°F (40°C). Allow space for ventilating 100 BTU/Hr.
Unit must be mounted in a 21/
8 ” deep 4” square steel
electrical box plus 1½” extension such that the heatsink is
spaced 1½” away from the wall in which the 4” square box
is mounted. Unit must be oriented such that the heatsink
fins run lengthwise vertically to permit natural upward
convection whether wall or plenum mounted. Allow a
minimum of 6” space above and below the unit and do not
block vertical airflow though the heatsink.
