Mend Glow-worm Ultracom 30 cxi Boiler Heating Controls

Glow-worm Ultracom 30 cxi?

Had my boiler about 12 months and can't think why it 'fires' up approx one hour before it is timed to go on - stops after about 5 minutes and then it comes on at the timed time - is it anything to do with my controlling it with the 'Climapro' which I think is fantastic?
