Discuss Clock not working on Worcester Bosch MT10RF/mechanical RF thermostat in the Central Heating Forum area at

    The clock has stopped working on my Worcester Bosch MT10RF/mechanical RF thermostat. I have changed the batteries but the clock still does not work.

    There is a radio link with the boiler as the light is green. And I can switch the heating on by just using the bottom left hand switch to put it on the day or night setting, but the clock isn't going round so I can't set the heating to come on / go off at particular times.

    There's nothing in the manual about trouble-shooting for a non-working clock. Will I have to buy a new one or can anyone think of anything else I could try?
    Thank you

    Have you tried re binding the clock/stat to the receiver

    Which version of the timer do you have? Is it the oblong one with the clock on the left. If so I would just upgrade it. They are not the best timers to be honest. (In my opinion)

    Yes it is that version. I'll take your advice and upgrade. Thanks for your help
