Hello, please can someone advice me how to get the controller to talk to the radio receiver unit. The radio receiver is fitted in the boiler through some pin connectors and the engineer did not know how to get it to work. I read through the instruction but still no luck. Vaillant advice the engineer ring them for further instruction. If anyone of you good guys can help will be much appreciated.
