Hello would appreciate some advice regarding making the controller and the radio receiver talking to each other, please.
We recently installed the above boiler and the engineer stated that he has never fitted a wireless controller before and could not get it to work. He suggested I read the instruction thoroughly which I have now done and see if I can get it to work. The radio receiver unit is fitted in the boiler through a few pin-connectors. I rang vaillant but they said that the engineer has to call for help. The engineer is coming on Saturday to complete the installation but just wondered if any you good guys could possibly help?
