WattStopper LMRC-212 Box Mount On/Off 2-Relay Digital Dimming Room Controller

The WattStopper LMRC-212 is a box mount digital lighting room controller designed to deliver on/off switching plus dimming control through two integrated relays. Built for line-voltage operation at 120 - 277-Volt AC with an 800 milli-amp rating, this controller is engineered to manage lighting loads in commercial spaces where both switching and digital dimming functionality are required from a single compact device. Finished in white, the LMRC-212 mounts directly into a standard electrical box, simplifying installation in new construction or retrofit lighting control projects. As part of WattStopper's digital lighting management platform, this room controller supports flexible zone-based lighting strategies that help facility managers and electrical contractors implement code-compliant, energy-conscious lighting control.

Key Features

  • Box Mount Design: Installs directly into a standard electrical box for a clean, space-saving installation in ceilings or walls.
  • 2-Relay Configuration: Two independent relays provide on/off switching combined with digital dimming for greater lighting zone control.
  • Digital Dimming Capability: Supports digital dimming control in addition to standard on/off switching, allowing for more flexible lighting scenes and energy management.
  • Voltage Rating: Rated for 120 - 277-Volt AC operation, making it compatible with common commercial line-voltage lighting circuits.
  • Amperage Rating: 800 milli-amp rating suited to the controller's relay switching and dimming control functions.
  • Finish: White housing finish for a clean, unobtrusive appearance in finished spaces.

WattStopper LMRC-212 – Frequently Asked Questions

1) Will the WattStopper LMRC-212 work on a 277V lighting circuit?
Yes. The LMRC-212 room controller is rated 120-277V AC, so it drops onto either a 120V or a 277V commercial branch circuit without a separate transformer. Its relay/dimming control rating is 800mA.
2) How does the LMRC-212 mount, and can it go in a junction box above the ceiling?
It is a box mount unit. The LMRC-212 installs directly into a standard electrical box, which is why it is commonly used in a ceiling or wall box rather than a panel enclosure. That makes it workable in both new construction and retrofit where you already have a box at the load.
3) Can one LMRC-212 control two separate lighting zones in a conference room?
Two zones, yes. The configuration is 2-relay on/off with digital dimming, and the two relays switch independently, so you can split a room into two controlled groups and dim each through the digital control side rather than only switching them.
4) How does the WattStopper LMRC-212 room controller differ from the Leviton LU107-DNW LuminaRF controller?
The LMRC-212 is a box mount digital room controller with a 2-relay on/off plus digital dimming configuration, rated 120-277V AC at 800mA, and it wires into a standard electrical box on the line-voltage side of the lighting circuit. The Leviton LU107-DNW is a LuminaRF series wireless controller using 0-10V phase control, so it addresses fixtures over a wireless link and a 0-10V dimming interface rather than through hardwired relays in a box. If the job calls for two switched and dimmed zones terminated at the box, the LMRC-212 matches that approach; if the design is built around wireless commissioning and 0-10V drivers, the LuminaRF device is the one that fits that architecture.
5) Is the LMRC-212 a switching-only relay pack or does it dim as well?
It does both. Where a plain relay pack only makes and breaks the load, the LMRC-212 pairs the two relays with digital dimming control, so a single box-mount device handles on/off plus dimming for the zone. If the room only ever needs switching, a dimming-capable controller is more device than the job requires.
6) Is the LMRC-212 a standalone controller or does it need to be part of a larger system?
It is built as part of WattStopper's digital lighting management platform, so it is intended to sit in that network of room devices and support zone-based control strategies rather than act as a lone dimmer. Plan the room's occupancy sensors, wall switches and network connections around that platform.
7) Can the Leviton LU107-DNW be used in place of a WattStopper LMRC-212?
They are not drop-in equivalents. The LMRC-212 is a box mount controller carrying two relays for on/off switching with digital dimming at 120-277V AC, 800mA, so it switches the line-voltage load itself. The Leviton LU107-DNW is a LuminaRF wireless 0-10V phase controller, which works through a wireless control path and a 0-10V dimming signal instead of two hardwired relay outputs. Swapping one for the other changes how the room is wired and commissioned, so the substitution only makes sense if the whole control scheme is being changed with it.
8) For a classroom retrofit with no new control wiring, which is the better fit: the LMRC-212 or the Leviton LuminaRF LU107-DNW?
Where pulling new control wire is the obstacle, the Leviton LU107-DNW LuminaRF controller is the one built around a wireless control link with 0-10V dimming. The WattStopper LMRC-212 is a box mount unit that lands in a standard electrical box and delivers two relays of on/off switching with digital dimming at 120-277V AC, which suits new construction or a retrofit where the box and the digital control runs are already in place or can be added.
9) What part number do I order for a 2-relay WattStopper dimming room controller, and what color is the housing?
The model and manufacturer part number are both LMRC-212, and the housing is white.
