Hello

My boiler (tank) was working perfectly fine but surprisingly I got a new boiler as part of a government scheme. I have been dealing with this company for 4 weeks but finding it really difficult: Basically 1. When the heating is turned on from the programmer unit, it wont switch off unless you switch the whole boiler off from the mains 2. Occasionally when the water is turned on from from the programmer unit the heating will also come on.

They told me it was my programmer unit so I replaced that but still the issue is not resolved. The engineer who installed it came and tried his programming unit but still same issue. He went back to report and now they are saying "they don't have anything to do with the electrics and the boiler is working fine, its the reciever unit.", but everything was working fine before they fitted the boiler????? I have attached pictures of the wiring they did to connect the boiler.

He changed it but didn't put mine back eventhough his was doing the exact same thing.
