WORCESTER 24 Si 2 Boiler how to work timer??

[Sparks1]

My Gran has an old Worcester 24 Si 2 Boiler. Does anyone know how to work the timer? See photo attached. Just want to know how to make it come on and go off at certain times?

Cheers mate thanks for that I get you. Just one thing then how does the boiler know what time it is? So for example I set it to come on at 8 and go off at 11 will the boiler automatically know the correct time or is there a way of setting the time?

Pretty sure this is correct using your picture......

Timer clock is On
Current time is 17.00
On is set at 05.00
Off is set at 09.45

Okay cheers again think I get you will give it a blast next time I'm at my grans as she keeps forgetting to turn the boiler off at night!

time now (current time) is where the arrow is above switch and you have to turn it one way only as shown by the other arrow round the edge
