WattStopper LMRC-111 – Frequently Asked Questions

1) What does the WattStopper LMRC-111 room controller actually do in a lighting system?
The LMRC-111 is a DLM room controller that switches and dims one lighting load. It carries a single 10A relay plus a 0-10V dimming output, so one zone of 0-10V drivers or ballasts gets both on/off control and dimming from the same device. It joins the room's other DLM devices (occupancy sensors, wall switches) over a free-topology Cat 5e DLM local network, and it has two RJ45 ports so devices daisy-chain rather than home-run back to a panel.
2) Can I control more than one lighting zone with an LMRC-111?
No. The LMRC-111 handles one load only, with one relay and one dimming channel. If the room has two or three separately switched or dimmed zones, you need a controller with a matching number of relays rather than stacking logic onto this one. Each load on a DLM controller gets its own status LED and its own On/Off/Dim local override button, so a single-relay unit gives you exactly one of each.
3) Will the LMRC-111 work with my LED drivers?
It dims 0-10V drivers. The dimming output is a 0-10V signal, so any LED driver or fluorescent ballast with 0-10V (sometimes marked 1-10V analog) control leads will work. Phase-cut drivers, DALI, and 2-wire ELV drivers will not, since there is no line-voltage dimming stage in this controller. Check the driver's control terminals before you commit the zone.
4) What happens to the lights if the room controller loses power?
The 0-10V signal opens on loss of LMRC power. An open 0-10V circuit is read by most drivers as full output, so the fixtures go to their maximum level rather than dark or stuck at a dim level when control power drops. Worth knowing on any job where a facility team expects a specific fail state.
5) Do I need a laptop or software to commission the LMRC-111?
No. DLM devices use Push n' Learn, so an electrician sets up the room by pressing buttons on the devices themselves, without a PC or handheld tool. The plug-together Cat 5e network also removes low-voltage wiring errors, since the devices identify themselves once connected. That matters on small retrofit rooms where sending a commissioning tech is more cost than the hardware.
6) What does the KO in the LMRC-111 description mean for mounting?
KO means the controller is a knockout-mount device. It fastens into a standard fixture or junction box knockout, so it installs at the luminaire or above the ceiling rather than in a wall box or a panel. The molded cable tie ring on the housing gives you strain relief for the Cat 5e drop at that mounting point.
7) Does the LMRC-111 count toward DesignLights Consortium qualification on a rebate application?
Yes. The LMRC-111 is listed as a DesignLights Consortium qualified networked lighting control system component, which is what most utility rebate programs ask for when they fund networked controls separately from the fixtures. WattStopper also publishes a Product Environmental Profile for it, which some public and institutional specs call for on sustainability scoring.
8) What cable do I run between the DLM devices in the room?
Cat 5e, in a free-topology layout. Free topology means you are not locked into a daisy chain or a bus with terminators; runs can branch as the ceiling allows. The LMRC-111 has two RJ45 ports so you can pass the network through to the next device, and the molded tie ring holds the cable so the connector is not carrying the weight of the drop.
9) Can occupants still control the lights directly at the controller if something goes wrong?
Yes. Each load has an On/Off/Dim local override button right on the controller, plus a status LED showing the relay state. If a wall station or sensor drops off the DLM network, maintenance can raise or lower the zone at the device itself while they sort the network out.
10) Is this room controller built to handle frequent switching in a high-traffic space?
The relay uses zero-crossing circuitry, meaning it switches at the point in the AC waveform where current is at zero. That reduces contact arcing, which is the usual failure mode when occupancy sensors cycle a relay many times a day in a restroom, corridor, or conference room. WattStopper cites it for reliability and increased product life.
