Likely by a faulty room stat or motorised valve for heating.

Doesn't matter if it was serviced 2 hours ago mate , parts fail , I reckon room stat or programmer either way get some one out

Turn room stat up?

23.5 degrees in my lounge. 11.38 pm no heating no Woodburners lit.

No need for heating unless you are ill, elderly or just plain soft.

25.6 C in my lounge and its almost 0000 hrs!

Its always a good idea to run CH for a few minutes every couple of weeks to exercise the motorised valves or diverter valve.

To be precise and critical as you put it often Tony, is a diverter valve not a motorised valve?

 

[Agile]

Many diverter valves in older boilers are hydraulically operated so cannot be described as "motorised".

Does the boiler suggest the MV to be anything else other then motor driven Tony?
Can you show me a sensible schematic that would, using above boiler, operate as S or Y plan, or for that mater any other Sundial plan?

I have edited my response several times by the way, so I can learn from what you may be implying. I look forward to being educated; disappear act will indicate post written based on wishful thinking only, not practical know how
