Components
Figure 1: Wattstopper LMRC-101 Digital Room Controller. This image shows the compact white housing of the controller with electrical wires (black, white, red) exiting from the top through a threaded conduit fitting. The bottom front face features a grid of small ventilation holes.
The LMRC-101 unit consists of a durable white plastic housing. Electrical connections are made via pre-attached wires, typically black, white, and red, secured by a threaded fitting at the top of the unit. The bottom section of the housing includes ventilation perforations for heat dissipation.
Setup and Installation
IMPORTANT: Installation must be performed by a qualified electrician and comply with all applicable electrical codes and regulations.
- Power Disconnection: Before beginning any work, ensure that power to the circuit is completely disconnected at the main service panel (circuit breaker or fuse box). Verify with a voltage tester.
- Mounting: Mount the LMRC-101 controller in a suitable electrical enclosure or junction box, ensuring it is securely fastened.
- Wiring Connections:
- Connect the black wire from the LMRC-101 to the unswitched line voltage (hot) wire.
- Connect the white wire from the LMRC-101 to the neutral wire.
- Connect the red wire from the LMRC-101 to the switched load wire (to the lighting fixture).
- Ensure all connections are tight and insulated with approved wire connectors.
- DLM Network Connection: Connect the DLM network cables (if applicable) to the designated ports on the LMRC-101, following the DLM system's specific wiring diagrams.
- Restore Power: Once all connections are secure and verified, restore power to the circuit at the main service panel.
- Testing: Test the functionality of the controller and the connected lighting load according to the DLM system commissioning procedures.
Operating Instructions
The Wattstopper LMRC-101 Digital Room Controller operates as part of a larger Digital Lighting Management (DLM) system. Its primary function is to provide on/off control for connected lighting loads based on commands received from other DLM devices (e.g., occupancy sensors, photocells, wall switches, or a central control system).
- Automatic Control: In a typical DLM setup, the LMRC-101 will automatically switch the connected lights on or off based on programmed schedules, occupancy detection, or ambient light levels as determined by other DLM components.
- Manual Override: If a DLM wall switch is connected, users can manually toggle the lights on or off, overriding automatic control temporarily or permanently depending on system configuration.
- System Commissioning: Initial configuration and programming of the LMRC-101's behavior (e.g., associating it with specific sensors or switches) are performed during the DLM system commissioning process, typically by a certified technician using specialized software.
Maintenance
The Wattstopper LMRC-101 Digital Room Controller is designed for minimal maintenance. Regular inspection and cleaning can help ensure optimal performance.
- Cleaning: If necessary, gently wipe the exterior of the unit with a soft, dry cloth. Do not use abrasive cleaners, solvents, or excessive moisture.
- Inspection: Periodically inspect the unit for any signs of physical damage, loose connections, or discoloration. If any issues are observed, disconnect power and consult a qualified electrician.
- No User-Serviceable Parts: The LMRC-101 contains no user-serviceable parts. Do not attempt to open or repair the unit.
Troubleshooting
If you experience issues with your LMRC-101 controller, refer to the following common troubleshooting steps. For complex issues, contact a qualified electrician or Wattstopper technical support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Lights do not turn on/off. | No power to the unit. Incorrect wiring. DLM system configuration error. Faulty load. | Check circuit breaker. Verify wiring connections (refer to installation section). Consult DLM system documentation or technician. Test the lighting fixture independently. |
| Lights flicker or behave erratically. | Loose wiring connection. Incompatible load type. DLM network interference. | Disconnect power and check all wiring connections. Ensure the load is compatible with the controller's specifications. Consult DLM system documentation or technician. |
| Unit is warm to the touch. | Normal operation (slight warmth). Overload condition. | A slight warmth is normal. If excessively hot, disconnect power immediately and check load current against specifications. Consult an electrician. |
