  If you are unable to make changes on the display of your Vaillant Controller, it might be due to a software error. You can try to resolve this by: 1. Pressing and holding the button on the top right of the control for more than five seconds to force a restart. 2. Switching off the mains switch on all heat generators for about 1 minute and then switching them back on.

  If the display on your Vaillant Controller remains dark, there are a couple of things you can try: * First, the batteries might be flat, so replace all of them. * If that doesn't work, it could be a software error. Try forcing a restart by pressing and holding the button on the top right of the control for more than five seconds. Alternatively, switch the mains switch on the heat generator that feeds the control off and back on again.
