How To Reprogram Somfy Remote: A Complete Technical Guide
Reprogramming a Somfy remote involves managing radio frequency pairings, clearing existing memory registers, and establishing a new rolling code link with the motor head. The entire procedure requires physical access to the programming buttons on both the original transmitter and the new or reset remote unit, typically operating on the standard 433.42 MHz RTS (Radio Technology Somfy) protocol.
Pre-Operation & Equipment Checklist
Executing a successful remote reprogramming operation requires a clear understanding of your specific Somfy motor type (tubular motors for blinds, awnings, or rolling shutters) and the exact frequency standards employed. Before starting, verify whether your system uses standard RTS or the bidirectional io-homecontrol protocol, as the programming sequences differ slightly in button-press durations and feedback indicators.
- Essential Gear and Tools: A functioning Somfy RTS transmitter, a paperclip or small specialized programming pin for recessed micro-switches, and a secure ladder if the motor head's physical programming button must be accessed.
- Prerequisite Knowledge: Identification of the programming button (often labeled PROG) on the back of existing remotes, and recognition of the motor's jog response, which consists of a brief up-and-down movement confirming command reception.
- Estimated Benchmarks: The procedure typically takes between 5 to 15 minutes per motor channel, with zero financial cost if utilizing existing functional hardware.
Step-by-Step Somfy Remote Programming Workflow
Step 1: Performing a Factory Reset via Motor Power Disconnection
When replacing a lost remote or completely clearing out conflicting programming memory, you must initiate a dual-breaking power cycle at the main electrical switch to force the Somfy tubular motor into programming mode.
- Turn off the power supply to the motor at the wall switch or circuit breaker for exactly 2 seconds.
- Turn the power back on for 10 seconds.
- Turn the power off again for 2 seconds, then back on. The motor should now perform a brief jog, indicating it is ready to accept new programming commands.
Warning: Never attempt a factory reset if multiple motors are wired to the same single circuit breaker, as this will wipe the memory limits of every connected shade simultaneously. Isolate the target motor individually before proceeding.
Step 2: Registering a New Remote Using an Existing Transmitter
If you already have a working Somfy remote and want to program an additional transmitter, you can clone the operational code without touching the motor's internal reset button.
- Take your currently working remote and use a paperclip to press and hold the recessed PROG button on the back until the motor gives a brief jog response.
- Take the new or unprogrammed remote and quickly press its PROG button for approximately one second.
- Observe the motor; it will execute a second jog, confirming that the new transmitter address has been successfully written to the motor's memory register.
Pro-Tip: Always double-check that you are pressing the PROG button on the correct channel if you are using a multi-channel Situo or Telis remote control model.
Step 3: Setting and Adjusting Motor Limit Switches
Once the remote is successfully paired, you must verify or reprogram the upper and lower limits to prevent mechanical stress on the blinds or shutters.
- Press and hold both the UP and DOWN buttons simultaneously until the motor jogs, then release.
- Run the motor to the desired upper limit position using the arrow keys, and press My and STOP simultaneously until the motor jogs.
- Run the motor down to the desired lower limit position, press My and STOP simultaneously until the motor jogs, and finally confirm the limit settings by pressing and holding the My button until the final jog occurs.

Common Site Failures and Field Fixes
- Root Cause: The motor fails to execute a jog movement during the initial power-cut sequence.
- Actionable Fix: The timing of the power interruption was likely inaccurate. Ensure the off and on intervals strictly adhere to the 2-second and 10-second windows. Use a stopwatch if necessary.
- Root Cause: The new remote controls the motor in reverse (pressing UP lowers the shade).
- Actionable Fix: Press and hold both the UP and DOWN buttons simultaneously until the motor jogs. Then, press and hold the MY button until the motor jogs a second time to reverse the rotation direction.
- Root Cause: Signal interference preventing the remote from registering with the motor receiver.
- Actionable Fix: Move closer to the motor head, clear any large metal obstructions near the window frame, and ensure fresh batteries are installed in the transmitter casing.
Frequently Asked Questions
How do I reset a Somfy remote if I lost the original one?
You cannot reset the remote itself via button combinations; instead, you must reset the Somfy motor by performing the manual double-power-cut sequence at the circuit breaker. Once the motor jogs, take your new remote and press its back PROG button until the motor jogs again, saving the new programming.
Can I program a Somfy multi-channel remote to control multiple blinds simultaneously?
Yes, multi-channel Somfy remotes feature an "ALL" channel setting or allow you to program the exact same individual channel address into multiple distinct motor memory registers during the pairing phase. This enables group commands without requiring hardwired group controllers.
What battery type do standard Somfy RTS remotes require?
Most standard handheld Somfy transmitters, such as the Telis and Situo series, utilize standard 3V lithium coin cell batteries, typically model CR2430 or CR2032. Replacing these requires sliding off the rear battery cover and matching the positive polarity upward.
Why does my Somfy motor stop halfway up or down?
This is typically caused by an obstruction in the track or a loss of calibration in the electronic limit settings. Run the shade completely down to the lower limit, let it stop automatically, and then recalibrate the upper and lower limits using the programming procedure outlined above.
