WattStopper LMRC-221 – Frequently Asked Questions

1) What size lighting load can the WattStopper LMRC-221 room controller handle?
The LMRC-221 is a single-channel dimming room controller rated 16A. One channel means one dimmed zone off this unit, so a room needing two independently dimmed zones needs a second controller or a multi-channel model. Dimming is triac-based forward phase control with a line voltage relay for on/off switching of the load.
2) Will the LMRC-221 dim LED drivers, or is it only for incandescent?
Forward phase (triac) dimming is what the LMRC-221 puts out, and it's specified as compatible with most load types using three selectable dimming curves so the output can be matched to the lamp technology. That covers forward-phase-dimmable LED drivers and incandescent alike. The one thing that decides it on your job is the driver itself: if the fixture's driver is 0-10V or reverse-phase only, this is the wrong controller and you want a 0-10V DLM room controller instead.
3) How do WattStopper DLM room controllers wire to the sensors and wall switches?
Low-voltage devices land on the LMRC-221 over Cat 5e patch cords with RJ45 ends, so occupancy sensors, wall stations and photosensors plug in rather than getting field-wired. Line voltage still has to be landed at the controller, but the control side is plug-and-play, which is what keeps a DLM job from needing point-to-point control wiring pulled.
4) Does the LMRC-221 need commissioning software to work out of the box?
No software is required to get it running. The DLM Plug n Go feature auto-configures the controller from the devices connected to it, so the room works on power-up. Scene and preset adjustment is still available: the controller stores a load preset level plus 16 scene preset levels per load.
5) Can the LMRC-221 do daylight harvesting for Title 24 style daylight zones?
Daylight harvesting is built in. The controller runs automatic dimming strategies that trim the electric light as daylight comes into the space, which is the control sequence a daylight zone next to windows or skylights is asking for. It needs a DLM photosensor on the Cat 5e network to read the daylight level.
6) What is the exact part number to specify for a 1-channel 16A WattStopper dimming room controller?
LMRC-221 is the catalog number, from WattStopper's DLM line of universal dimming room controllers. Spec it as the 1-channel, 16A forward phase unit so it isn't confused with the multi-channel models in the same family.
7) Can I use one LMRC-221 to dim several rooms, or do I need one per room?
One per room is the design intent. A DLM room controller serves a single room's load, and the LMRC-221 carries one 16A dimmed channel, so separate rooms with separate switch legs each need their own controller. Where a large open area is split into daylight zones that must dim independently, treat each zone as a load and count a channel for it.
8) Is the LMRC-221 suitable for a school or hospital retrofit, or is it only for offices?
Commercial office, education, healthcare, retail, hospitality, government and industrial spaces are all covered applications for this controller. What makes it work in a retrofit is the Cat 5e control wiring: sensors and wall stations plug in with patch cord rather than requiring new control conductors pulled through finished ceilings.
