You must first do an io reset and unpair your thermostatic valve io from your box, using the following steps:

1. Wake up your product.
2. Press the "-" and "+" buttons for 7 seconds until the "io" logo is displayed and release the buttons

If the procedure was successful, the thermostatic valve displays "OK".

Then restart the pairing process with your TaHoma® box by pressing and holding the "-" and "+" buttons for 3 seconds, until the pairing logo is displayed.

The pairing is now started for 10 minutes, so please make sure that you register your valve io in your TaHoma® box within these 10 minutes.

If the above procedure still doesn't work to pair your valve, reset your thermostatic valve by pressing the "-" and "+" buttons simultaneously for 12 seconds and release when the reset icon is displayed, then try the pairing procedure again.

If you still have problems, please contact the Somfy Hotline.
