    Problem with dt20 programmer on worcester 30cdi system boiler

    I have a problem with a newly installed system. On the display on the boiler the arrow which selects between 'off' 'timed' 'once' and 'on' for heating doesn't move it just stays on 'on'. Is this a problem with the programmer, the rf stat or a wiring problem. The hot water works fine.
