legrand LMRC-110 Series Room Controllers
Product Information
Specifications
- Plenum-rated controllers with line voltage relay(s) and 0-10 volt dimming output(s)
- Plug n’ GoTM automatic configuration for quick installation and maximum energy efficiency
- Knockout mounting for easy installation; Class 1 and/or Class 2 connection for 0-10V wiring
- Available with or without metering (+/- 2% accuracy)
Product Usage Instructions
Description
LMRC-110 series room controllers include one or two relay(s) to switch a
total of 10 amps, a high-efficiency switching power supply, and dual 0-10 volt
outputs per relay for control of dimmable loads including compatible LED
drivers or electronic ballasts. They are the foundation of a Digital Lighting
Management (DLM) system and allow integration of occupancy sensors,
daylighting controls, and switches for energy-efficient control.
Operation Features
- Store 16 scene preset levels for each load
- Support energy-saving manual-on, partial-on, and dimming control strategies
- Room controllers include circuitry to open their 0-10V signal on loss of LMRC’s power
Plug N’ Go Automatic Configuration
Applications
LMRC-110 series room controllers are ideal for single or multiple zone
on/off or dimming control applications including private offices, open
offices, conference rooms, and classrooms. Metering models help facility
managers who want to track building power usage for lighting or other loads.

Q: What are the available options for the LMRC-111 series room controllers?
A: The LMRC-111 series is available as follows:- LMRC-111: 1 Relay Room Controller, 0-10V dimming
- LMRC-111-U: 1 Relay Room Controller, 0-10V dimming, BAA/TAA compliant*
- LMRC-111-M: 1 Relay Room Controller, 0-10V dimming, with meter
- LMRC-111-M-U: To be continued…
DESCRIPTION
LMRC-110 series room controllers include one or two relay(s) to switch a total
of 10 amps, a high-efficiency switching power supply and dual 0-10 volt
outputs per relay for control of dimmable loads including compatible LED
drivers or electronic ballasts. They are the foundation of a Digital Lighting
Management (DLM) system, and allow the integration of occupancy sensors,
daylighting controls and switches for energy-efficient control.
OPERATION
LMRC-110 series room controllers operate on one 120 or 277-volt, 10-amp feed and provide Class 2 power to sensors and switches via the DLM local network. Once powered up, Plug n’ Go automatically configures system components for the most energy-efficient operation. The room controllers then dim or switch lighting or motor loads in response to input from the communicating devices. When a dimming input is received, the relay switches on when the dimmed level rises above zero, and off when it reaches zero, to coordinate control of power and the 0-10 volt signal to the load. They also monitor the current draw of the total connected load. Each room controller stores up to 16 scene preset levels for each dimmed output. Additionally, the LMCT-100-2 wireless configuration tool can be used for load configuration.
Room controllers include circuity to open their 0-10V signal on loss of LMRC’s power, so any separately powered ballast or driver connected to those 0-10V wires will go to full brightness.
PLUG N’ GO AUTOMATIC CONFIGURATION
DLM room controllers manage Plug n‘ Go automatic system configuration, which establishes functionality based on the installed components. When room controllers are connected only to occupancy sensors, the system defaults to automatic on/off operation. If a wall switch is added to a system with one load, the load defaults to manual-on/automatic-off operation. If there is a wall switch and multiple loads, load one turns on automatically, while additional loads default to manual-on control; all loads turn off automatically. At system startup, default dimming parameters are established including: levels for scene presets 1-4; fade times; and fade and ramp rates. Dimming and system parameters may be customized using Push n’ Learn.
APPLICATIONS
LMRC-110 series room controllers are ideal for single or multiple zone
on/off or dimming control applications including private offices, open
offices, conference rooms and classrooms. Metering models help facility
managers who want to track building power usage for lighting or other loads. A
network bridge (LMBC-300) is required to expose DLM local network power
measurement readings to a segment manager or BAS.
