ch not turning ff

[galwag]

Can anyone help with a fault on a ariston euro combi ?
The problem is the central heating does not switch off even with the built in timeclock removed. There is no room stat fitted and have checked microswitches on divertor valve. Does it have a built in frost stat ?
The boiler is fitted in a garage but does not have an external frost stat.
I would appreciate a service/installation manual that I could download. This model is not listed on aristons/mtf website.
