Hi\n\nWe have a 20year old C bus system. The light switches have started flickering and become non responsive throughout the house. If I continuously press a button quickly it will eventually work. \nSpoke to an Electricain and they said that it’s tough to repair and the older parts aren’t replaceable and need new parts which may not be able to talk to the old network. He found a couple burnt out relays when inspecting. \nHelp!
