my clock will not stop flashing and the timer which i have set wont come into operation when i switch the select button to on it skips the timer settings twice and once and goes straight to on. how do i fix this. the boiler is a worcester 350.

My one flashed due to a timer conflict, I'd set1 on1 at 7:30am, off1 at 8:00 am, on2 at 5:00pm and stupidly off2 at 10:00 am for Friday. the timer flashed and it wouldn't go on on fridays. Worked ok other days though.

A work by would be get a radio remote timer/thermostat and wire that in instead bypassing the boiler timer if clearing any conflicts doesn't work.
