Mend Honeywell Boiler Central Heating

Hot water but no central heating?

Hi,

having an odd problem with the heating today. i can get as much hot water as i want but cannot persuade the CH to come on.

burner kicks in if hot water is run but nothing happens even when CH is turned directly on.

When i switch the motorised valve (honeywell) to manual it causes the boiler\burner to kick in before almost instantaneously reseting itself.

any ideas?
