5. Installation
Tools Required: Screwdriver, Wire Strippers.
- Turn Off Power: Before starting, ensure power is disconnected at the circuit breaker to avoid electrical shock.
- Prepare Wiring: Strip approximately 1/2 inch (12mm) of insulation from the wires.
- Connect Wires: Connect the low voltage wires to the appropriate terminals on the back of the switch. The LMSW-105-W typically uses RJ45 connections for system integration. Refer to your system's wiring diagram for specific connections to the LM dimming room controller or other compatible devices.
- Mount Switch: Carefully place the switch into the wall box and secure it with the provided mounting screws.
- Install Wallplate: Attach the decorative wallplate (not included) over the switch.
- Restore Power: Turn power back on at the circuit breaker.
6. Operation
Basic Control:
- Main Rocker Switch: The large rocker switch on the left typically controls the primary load or acts as a master on/off for the selected scene. Press the top for ON/Raise, bottom for OFF/Lower.
- Scene Buttons (1-4): The four smaller buttons on the right are used to recall pre-programmed lighting scenes. Pressing a scene button will activate the corresponding lighting configuration.
Active Dim Feature:
While a scene is active, you can temporarily adjust the dimming level of individual loads within that scene using the main rocker switch. This adjustment is temporary and will revert to the programmed scene level when a new scene is selected or the system is reset.
7. Configuration
Plug n' Go™ Automatic Configuration:
The LMSW-105-W supports Plug n' Go™ functionality, allowing for automatic detection and basic configuration when connected to a compatible Wattstopper lighting control system. Upon initial power-up, the switch will attempt to establish communication and configure itself with default settings.
Push n' Learn for Personalization:
For advanced personalization and scene programming, the Push n' Learn feature allows users to customize the lighting levels associated with each scene button. Refer to your specific lighting control system's manual for detailed instructions on how to enter Push n' Learn mode and program scenes. Typically, this involves setting the desired lighting levels for each load and then saving them to a scene button by pressing and holding the button for a specified duration.
8. Maintenance
The Wattstopper LMSW-105-W switch requires minimal maintenance.
- Cleaning: To clean the surface of the switch, use a soft, damp cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish.
- Inspection: Periodically inspect the switch for any visible damage or loose connections. If any issues are found, disconnect power and consult a qualified electrician.
