Hi
Our boiler is controlled via a honeywell Smartfit "Y" system and the boiler started repeatedly relighting. The room unit then reported a fault in the connection between it and the base unit.
The fault finding check list suggests
a) switch the unit off and on again, which I did but to no avail b) replace the room unit, we have a spare 7 day unit so I tried using that, still the same. c) replace the base unit.
The question is do you have to be corgi registered to do (c)?
Thanks
Ross
