WattStopper LMRC-101 – Frequently Asked Questions

1) Will the WattStopper LMRC-101 room controller work on a 277V lighting circuit?
Yes. The LMRC-101 DLM room controller is a universal-voltage device that runs on 120-277V, so it drops onto a 277V commercial branch circuit as readily as a 120V one. That covers the two voltages most commercial fluorescent and LED lighting branches are fed at, so you order the same part regardless of which panel the room lands on.
2) Can a DLM single relay room controller be installed above the ceiling in a return-air plenum?
Yes. The LMRC-101 is plenum rated, so it is approved for installation in air handling spaces above the ceiling. That is how these controllers are normally mounted, sitting near the fixtures with the Cat 5e runs dropping down to the wall switches and sensors.
3) How many lighting zones does a WattStopper LMRC-101 control?
One. The LMRC-101 is a single relay controller, on/off switching only, so it handles one load in one room. If the space needs two separately switched zones or bi-level switching off two relays, a single relay controller is the wrong part and you want a multi-relay DLM room controller instead. Bi-level strategies in a DLM room using the LMRC-101 come from combining it with other DLM devices on the same local network, not from the controller itself.
4) Does the LMRC-101 dim the lights or just switch them?
Switching only. It is an on/off relay controller with no dimming output, so if your fixtures are 0-10V dimmable and the spec calls for dimming or daylight harvesting with continuous dimming, this is not the controller for that room. Use a dimming DLM room controller. The LMRC-101 is the right choice where the sequence of operations is simply manual-on, occupancy-off.
5) What cable runs between a DLM room controller and the occupancy sensors and wall switches?
Standard Cat 5e with RJ45 plugs. The DLM local network uses ordinary Cat 5e patch cabling between the room controller and the other devices in the room, which means the low-voltage side is plug-in rather than terminated on screws, and the controller supplies power to those devices over the same cable. An electrician wiring the line voltage side still needs the 120-277V feed and the switched load landed on the controller.
6) Does the LMRC-101 need to be programmed or commissioned after install?
Not for a basic room. The controller uses Plug n Go automatic configuration, so when the sensors and switches are plugged into the DLM network it self-configures to a working default sequence without a laptop or a commissioning tool. You can still change the sequence later with DLM configuration tools, but a straightforward manual-on room works out of the box, which is the main labor saving on a retrofit where you are doing many rooms in a night.
7) Does the LMRC-101 come with an occupancy sensor or wall switch in the box?
No. The room controller is the relay and power supply for the room, and the occupancy sensors and digital wall switches are separate DLM devices you order alongside it. Budget the room as controller plus sensor plus switch plus the Cat 5e patch cables that tie them together, or the crew arrives with a controller and nothing to plug into it.
8) Will the LMRC-101 fit in the space I have above the ceiling tile?
The controller is a compact box measuring 4.53 x 4.0 x 2.71 inches and weighing 0.6 lb, about 55.61 cubic inches of volume. That clears a standard tile grid cavity with room to spare, and the light weight means it does not need dedicated structural support the way a larger panel would.
9) Is the LMRC-101 a whole-building lighting control panel or a room-level device?
Room level. Each LMRC-101 serves one room and its own local DLM network of sensors and switches, so on a building job you buy one per controlled room rather than one large panel per floor. That architecture is why standardizing on it across a portfolio is straightforward: the same part number repeats room to room, and a failed unit swaps out without touching anything else in the building.
10) What is the exact part number to specify for the WattStopper single relay DLM room controller?
LMRC-101 is the manufacturer part number, WattStopper brand, from the DLM (Digital Lighting Management) line. Spec it as WattStopper LMRC-101 for the on/off single relay, 120-277V room controller. The higher numbers in the LMRC family are different devices with more relays or dimming outputs, so the 101 suffix is the part of the number that matters on the order.
11) Is there environmental documentation available for the LMRC-101 for a green building submittal?
The LMRC-101 carries a Product Environmental Profile, which is the manufacturer's published environmental declaration for the device. On LEED or a sustainability-focused spec that document plus the DesignLights Consortium system qualification are the two items typically requested for a networked lighting control submittal. Country of origin on the unit is China.
