Why doesn’t the thermostatic valve light up when I remove the product's tab?
When you initially remove your new valve's tab, it should light up.
If it doesn't, please perform the following steps to determine the reason:
- Open the thermostatic valve batteries cover (turn the thermostatic valve).
- Remove the batteries from the Somfy thermostatic valve io for 1 minute, ensure that they are not damaged and put them back in.
- Make sure that the metal flap is properly closed.
- Check that the LEDs on the product light up.
- If the LEDs do not light up, make sure that new batteries are used by changing the batteries.
If you still have problems, please contact the Somfy Hotline.
