​If you experience a blank controller there could be a few reasons
Before we come out please check following.
- That the power is connected to the Ventis in the roof (check that the plug is plugged in)
- Check your circuit board to make sure that nothing is switched off
Have you had any trades people, electricians changing any electrical cabling that may have changed the electrical configuration so that is no long power to the power point that the Ventis is connected to?
Also gently pull the cover of the controller off and unscrew the controller. Check that the blue data cable is still connected to the 'data socket', it needs to be clicked in.
If there you have checked all of the above and the controller is still blank you need to reply to your case email to update us.
We will have to book in a customer service technician to come out reprogram/replace the SCU & Controller (fees apply)
