After a few days of trying different things I have isolated it some more. Ultimately a plumber will be called, but I want to try and see if I can get a good idea of it first.
BOTH bathroom (ensuite & family) rads, unless they are totally *off* on the TRV valve, cause the boiler to come on (bypassing the new thermostat) and heat up to scorching hot.
No other rads in the house have this, so I can only assume these bathroom rads have some sort of design/feature to warm up the bathrooms for showers/towel drying etc etc.
Has anyone heard of a feature where the bathroom radiator/towel rail warms up x hours after the hot water to dry any towels left in the room? Could there be a hidden timer somewhere that is set up for this?
