How to use a mechanical clock on a Ravenheat 820/20 combi boiler?

I have just moved into a new place with an old Ravenheat 820/20 boiler which has a mechanical clock, and I dont know how to use it. I have searched online, but have not been able to find anything and when I called the Ravenheat helpline werent able to help me! So I would be greatful for any information on how to use the mechanical clock. Thanks

they would normally have 3 settings: 1 = on 0 = off clock symbol = timed.

to set timer put in clock symbol position and push in the small black pins on the outer of the clock for the times you would like it to be on. ie if you want 6-8 in the morning then put all the pins between 6-8 in the down position and as long ast he timer moves then it should come on ok
