I've just fitted a room stat to my friendly format 80e. Removed the link between 22 - 23 and connected the wires to thees terimals. But the temp control on the boiler itself is still working together with the room stat. This seems to be defeating the fitting of a external stat. Any Help..
the boiler temp sensor will still work and will switch the boiler off if the returning water is at the set level even if the room stat is still demanding more heat.
