Today my heating has been working but for some reason it's only on for 2 hours at a time and then goes off. I have a Worcester boiler and a Siemens RDJ1ORF timer. I have it sent on Run and Auto, do you know what the problem could be with it please?
You really need to narrow it down,is the programmer telling it to switch off,is the receiver losing the signal from sender,try moving the sender nearer to receiver,does the boiler start up again straight away after it has switched off.Some wireless units will do this if it loses signal
