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

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: #
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.
Operate the Covering(s)
To raise the window covering(s), press the UP button.
To lower the window covering(s), press the DOWN button.
Stop Movement at Any Time
Press the STOP button to halt the movement of the window covering(s) at any position.
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.
#
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 #
Phillips and flathead screwdrivers
Drywall saw
Wall stud finder
Painter’s tape (or similar non-marring tape)
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.
