Adding a DecoFlex WireFree™ RTS Wall Switch

Initial Installation Guide

⚠️ Important: During the initial setup, it’s recommended to only provide power to the motor or RTS receiver that you are programming. This prevents accidentally pairing with unintended devices.

Step-by-Step Instructions:

1. Put the RTS Motor or Receiver into Programming Mode

  • Follow the specific instructions included with your RTS motor or receiver to enter programming mode.

  • The motor or receiver will indicate it's ready (usually via movement or LED feedback).

2. Select the Channel on the DecoFlex Switch

  • Press the desired channel button on the DecoFlex switch.

  • The LED next to the button will light up, confirming your selection.
    (See Figure 1 for channel layout.)

3. Pair the Switch with the Motor or Receiver

  • Using a paperclip or similar tool, press and hold the small programming button on the DecoFlex switch for no more than 1 second.

  • The motor or receiver will confirm pairing—this may be a jog of the motor or a blink of an LED.

Once completed, the DecoFlex WireFree RTS switch will be paired and ready to control the selected motor or device.

Adding Additional Channels or DecoFlex WireFree™ Wall Switches

⚠️ Tip: You can expand your setup by adding more channels or additional DecoFlex switches. Follow the steps below to pair new devices with your existing motor or RTS receiver.

Step-by-Step Instructions:

1. Put the Motor or Receiver Back into Programming Mode

  • Using a paperclip or similar tool, press and hold the program button on the existing DecoFlex switch or channel that is already paired.

  • Hold for about 3 seconds.

  • The RTS motor or receiver will confirm programming mode (usually by jogging or flashing).

2. Select the New Channel or Switch to Add

  • On the new DecoFlex switch, press the channel button you want to pair.

  • The LED next to the button will light up, confirming your selection.
    (Refer to Figure 1 below for button locations.)

3. Finalize the Pairing

  • With a paperclip or tool, briefly press the programming button on the new DecoFlex switch (no more than 1 second).

  • The RTS motor or receiver will confirm the new pairing.

Deleting Specific Channels or DecoFlex WireFree™ Wall Switches from Memory

⚠️ Important: When deleting, do not perform the procedure on the device or channel you are trying to remove. Always initiate the process from a previously programmed switch or channel.

Step-by-Step Instructions:

1. Enter Programming Mode Using an Existing Channel

  • Using a paperclip or similar tool, press and hold the program button on an already programmed DecoFlex switch or channel (not the one being deleted).

  • Hold for about 3 seconds.

  • The RTS motor or receiver will confirm that it's in programming mode (usually via a jog or light response).
    📌 Refer to Figure 1 below for button locations.

2. Select the Channel You Want to Delete

  • On the DecoFlex switch to be removed, press the channel button you want to delete.

  • The LED next to the button will light up to confirm the selection.

💡 Only one channel can be deleted per session. To remove multiple channels, repeat the full process starting at Step 1 for each.

3. Confirm the Deletion

  • On the same DecoFlex switch, briefly press the program button (no more than 1 second).

  • The RTS receiver or motor will confirm the deletion of that channel or switch.

Operating Window Coverings with the DecoFlex WireFree™ RTS Switch

🔧 Tip: Ensure your switch has been properly programmed before attempting to operate your window coverings. Refer to the programming section if needed.

Step-by-Step Instructions:

1. Select the Desired Channel(s)

  • Press the CHANNEL BUTTON(s) that correspond to the window covering(s) you want to control.

  • The LED next to each button will illuminate to confirm selection.

  • To deselect, press the same channel button again — the LED will turn off.

2. Operate the Covering(s)

  • To raise the window covering(s), press the UP button.

  • To lower the window covering(s), press the DOWN button.

3. Stop Movement at Any Time

  • Press the STOP button to halt the movement of the window covering(s) at any position.
    📌 See Figure 2 for button locations.

4. Use a “Preferred Position” (If Programmed)

  • If your system has a Preferred Position (intermediate preset), press the STOP button while the covering is stationary to move it to that saved position.
    📄 Refer to your specific motor or RTS receiver’s installation manual to program or update this feature.

⚠️ Notes:

  • If you press UP, DOWN, or STOP without first selecting a channel, the DecoFlex will default to the last selected channel(s).

  • Selecting multiple channels for group control will result in sequential activation, meaning each channel will activate one after the other (from channels 1 through 5).

Installing the DecoFlex WireFree™ RTS Wall Switch

With Included SOMFY Low Voltage Mounting Bracket

About the Mounting Bracket

The included SOMFY low-voltage bracket allows you to install your DecoFlex WireFree RTS switch without an electrical box.
It supports two configurations:

Configuration 1: Mount Adjacent to Existing Light Switch

Use this setup when installing the DecoFlex switch next to a pre-existing Decora-style light switch.

  • Designed to fit inside a double-gang (2-gang) wall plate for a seamless, professional finish.

  • ⚠️ Do not use with “old-work” or retrofit electrical boxes.

  • ✅ For best wireless performance, avoid metallic electrical boxes.

Configuration 2: Stand-Alone Installation

Use this setup when mounting a single DecoFlex switch in its own space.

Tools You’ll Need

  1. Phillips and flathead screwdrivers

  2. Drywall saw

  3. Wall stud finder

  4. Painter’s tape (or similar non-marring tape)

  5. Pencil or marker

🔧 Installation Steps (Adjacent Mounting – Configuration 1)

1. Power Down and Prep

  • Turn off power to the existing wall switch at the breaker.

  • Remove the existing wall plate to expose the electrical box.

2. Locate the Stud

  • Use a stud sensor to find the stud nearest the exposed box.

  • Mark the stud location with tape or pencil for reference.

3. Position and Mark Bracket

  • Take the flat side of the mounting bracket and align the thin edge to the outside of the existing box (opposite the stud).

  • Ensure it aligns vertically with the existing switch.

  • Trace the inner edge of the bracket onto the drywall with a pencil.

4. Cut the Wall Opening

  • Carefully cut along your traced lines using a drywall saw.
    ⚠️ Do not cut larger than the outline.

  • Recommended hole size: 1 5/8” W x 3 7/16” L

5. Insert the Bracket

  • Slide the bracket into the cut hole with the thin side facing the existing switch box.

6. Secure the Bracket

  • Bend the built-in tabs 90 degrees behind the drywall to hold the bracket snugly in place.

7. Install the DecoFlex Switch

  • Position the DecoFlex RTS switch into the bracket, aligning the screw holes.

  • Tuck the wire antenna behind the wall, keeping it as straight as possible.

  • Secure the switch with the included screws.

8. Finish with a 2-Gang Wall Plate

  • Attach a double-gang Decora-style wall plate over both the existing switch and the DecoFlex to complete your installation.
