WattStopper LMRC-211 DLM Room Controller with 1 Relay and 0-10V Dimming Control

The LMRC-211 is a plenum-rated digital lighting management room controller with one line-voltage relay and a 0-10V dimming output. It connects via Cat 5e cable with RJ45 connectors for plug-and-play installation that eliminates field wiring errors. The controller supports 120/230/240/277V and 347V configurations and carries DesignLights Consortium (DLC) qualification, making it eligible for utility rebate programs.

Features

  • Multi-Voltage Support: Compatible with 120/230/240/277V and 347V electrical systems.
  • Control Strategies: Supports manual-on, bi-level, tri-level, and dimming control strategies for energy optimization.

WattStopper LMRC-211 – Frequently Asked Questions

1) Will the WattStopper LMRC-211 room controller work on a 277V lighting circuit?
The LMRC-211 is offered in multi-voltage configurations covering 120/230/240/277V, plus a separate 347V model. So a 277V branch circuit is within what the controller family handles, and Canadian 347V jobs are covered by the 347V version rather than the standard one. Pick the configuration that matches the circuit feeding the fixtures, not the low voltage side, since the DLM link between devices runs on Cat 5e.
2) Can a DLM room controller be installed above the ceiling in a return air plenum?
Yes. The LMRC-211 is plenum rated, so it can sit in an air handling space above the ceiling, which is where these room controllers usually go, near the fixtures they switch. It carries a line voltage relay and a 0-10V dimming output in the same enclosure.
3) How many lighting zones can the WattStopper LMRC-211 control?
One. The LMRC-211 has a single relay with one 0-10V dimming output, so it drives one switched and dimmed load. A room that needs separate control of, say, the whiteboard row and the general lighting needs a controller with more than one relay, or a second controller on the same DLM link.
4) Do 0-10V dimming room controllers need to be programmed after installation?
Not for basic operation. The LMRC-211 uses Plug n Go automatic configuration, so once the occupancy sensor, wall switch and controller are linked with Cat 5e patch cords it comes up with a working energy saving configuration out of the box. Programming is what you do to change the default behavior, not to make it run.
5) What wiring runs between the WattStopper DLM room controller and the sensors and switches?
Standard Cat 5e with RJ45 connectors. The sensors, wall stations and the LMRC-211 plug into each other, which is why an electrician can pull the low voltage in the same way they would data cable and not worry about polarity or terminal mistakes. Line voltage still lands at the controller for the relay.
6) Does the WattStopper LMRC-211 qualify for a utility lighting control rebate?
It is a DesignLights Consortium qualified system, which is the qualification most utility programs key their networked lighting control rebates to. That matters on retrofit work in offices, schools and healthcare buildings where the rebate is carrying part of the project cost. Confirm the specific program's requirements with the utility, since program rules vary by territory.
7) What control strategies does the WattStopper LMRC-211 support for meeting energy code?
Manual-on, bi-level, tri-level and dimming. Manual-on is the strategy most commonly required by code in offices and classrooms, and bi-level or tri-level covers spaces where a stepped reduction is specified instead of continuous dimming. All of them run off the one relay plus the 0-10V output.
8) Is the WattStopper LMRC-211 the right part number for a 0-10V dimming room controller?
For a single relay with 0-10V dimming, the manufacturer part number is LMRC-211. The 211 designation is the one relay, dimming version of the DLM room controller line, so specify it by that number when the drawing calls for one dimmed zone per room.
9) Can a room controller hold preset light levels for different room uses?
Yes. The LMRC-211 stores load preset levels and 16 scene preset levels for each load, so a multipurpose room, a conference room or a classroom can be recalled to a set level from a wall station rather than dimmed by hand every time.
