Product Overview

Images show different models of Wattstopper low voltage switches (LMSW-210, LMSW-211, LMSW-220, LMSW-222, LMSW-241, LMSW-250) with varying button configurations.

This unit is pre-set for Plug n' Go™ operation; adjustment is optional.

For full operational details, adjustment, and more features, see the DLM System Installation Guide provided with Wattstopper room controllers, and also available at www.legrand.us/wattstopper.

Installation Notes

Installation must comply with all applicable regulations, local, and NEC codes.

Wire connections must be rated for the wire size used (lead and building wiring).

For Class 2 DLM devices and wiring: Connect only to a Class 2 power source. Do not reclassify and install as Class 1, or Power and Lighting Wiring.

Do not apply cleaning solvent directly to the unit. Apply cleaning solvent onto a cloth, then wipe the unit to clean it.

SPECIFICATIONS

BUTTONS AND INDICATORS

Status/Config LED: Indicates device status.

LEDs show light level setting (LMSW-211 only).

Button Functions:

• Tap: Fade to OFF
• Press & Hold: Ramp Down
• Double Tap: Immediate OFF with no fade

Buttons can be set to toggle on/off or to function as a scene switch:

• Tap when load OFF: Turn ON to last level
• Tap when load ON: Go to full bright
• Press & Hold: Ramp Up
• Double Tap: Immediate ON with no fade

Configuration Button: Located on the right side of the Legrand badge/IR window.

Active Dim Function: When a scene button is tapped, room rockers temporarily control the loads assigned to that button, allowing the user to dim the selected scene. The switch LED flashes to indicate status. After five seconds, the rockers revert to their normal load assignments. When a load button is double-tapped, all rockers in that room will go into active dim mode as well (for 5 seconds). Active Dim can be disabled on LMSW-2xx switches using LMCS-100 software.

MOUNTING THE SWITCH

Diagram Description: Illustrates the physical mounting of the switch in a wall box, showing the switch assembly and wiring points.

WARNING: Do not install to cover a junction box having Class 1, 3 or Power and Lighting Circuits.

CAUTION: To connect a computer to the DLM Local Network, use the LMCI-100. Never connect the DLM Local Network to an Ethernet port – it may damage computers and other connected equipment.

CONNECTIVITY

The illustrations show examples of free-topology wiring. The LMSW switches communicate with all other Digital Lighting Management devices connected to the low voltage DLM Local Network, regardless of their position on the network.

Diagram Description: Illustrates DLM Local Network connectivity. It shows line voltage connections to devices like occupancy sensors and 0-10V drivers/ballasts. Low voltage (Class 2) wiring using LMRJ cables connects LMSW switches, sensors (occupancy, daylighting), and room controllers (LMRC-112, LMRC-21x) to the DLM Local Network. It depicts different sensor types (line voltage, 0-10V, ceiling mount, corner mount) and their connection to the room controller and loads.

PLUG N' GO OPERATION (PNG)

Each load is automatically assigned to a switch button.

• If there are more buttons on a switch than there are loads, the extra button(s) do nothing and blink when pressed.
• If there are fewer buttons on a switch than there are loads, the last button controls all remaining loads.
• The LMSW-241 auto-configures as a scene switch for all lighting loads. A button's scene percentages can be changed by pressing and holding for 5 seconds while the room is in the desired state.

Diagram Description: Shows Plug n' Go load binding for LMSW switches (LMSW-210, LMSW-211, LMSW-220, LMSW-222, LMSW-241, LMSW-250) in a room with up to 5 loads, connected to LMRC-112 or LMRC-111 room controllers. The LMSW-241 diagram indicates scene percentages (100%, 75%, 50%, 25%).

UNIT ADJUSTMENT - PUSH N' LEARN (PNL)

Load Selection Procedure: A configuration button allows access to our patented Push n' Learn™ technology to change the binding relationship between switch buttons and loads.

Step 1: Unlock Configuration Button

The configuration button will lock after any of the following events: PnG lock command transmitted (occurs upon PnL exit); After twelve hours of being unlocked (first boot or a manual unlock); The button is manually locked (as described in Step 5).

To check if it is unlocked: Press the configuration button on the right-side of the Legrand badge. If the top button LED flashes red, the configuration button is unlocked. Skip to Step 2 – Enter Push n' Learn.

If the top button LED did not flash red, the configuration button is locked. Press-and-hold the configuration button and the top-most button on the switch simultaneously until the top button LED flashes red (approximately 3 seconds). This signals that the configuration button is unlocked.

Step 2: Enter Push n' Learn

1. Press and hold only the configuration button for 3 seconds, until the Red LED on the switch begins to blink.
2. When you release the switch's configuration button, the red LED on other communicating DLM Local Network devices begins to blink.
3. The DLM Local Network is now in PnL mode. The Red LEDs continue to blink until you exit PnL mode.
4. All loads in the room turn OFF after entering PnL. After one second, one load turns ON. This is Load #1, which is bound to switch button #1 as part of the Plug n' Go factory default setting. The White LED will be ON for all switch buttons and sensors that are bound to this load.
5. Note: For the top button, since it is blinking red while in PnL, the LED for that button will alternate between Red and White if the button is bound to the load or Red and Off if the button is not bound to the load.

Step 3: Load Selection

1. Press and release the configuration button to step through the loads connected to the DLM Local Network. As each load turns ON, note which devices (switch buttons and sensors) are showing the white LED. These devices are currently bound to the load that is ON.
2. To unbind a switch button from a load, press the switch button while its white LED is ON. The white LED turns OFF to indicate the button no longer controls the load that is currently ON.
3. Pressing the switch button again while the load is ON rebinds the load to the button and the white LED illuminates.

Step 4: Exit Push n' Learn

Press and hold the configuration button until the red LED turns off, approximately 3 seconds.

Step 5: Lock Configuration Button (Optional)

If the configuration button is unlocked and you wish to manually lock it, press-and-hold both the configuration button and the top-most button on the switch simultaneously until the top button LED lights red (approximately 3 seconds).
