Timer issue...won’t stay in ‘timed’ mode, can only do ‘on’ or ‘off’

[Carly (Streatham Hill)]

Morning,

Sorry if this post is me being a little thick but for some reason my boiler timer - the old school type in a Capriz 25) doesn’t want to stay in the mode that automatically turns the boiler on and off!

If you put it into ‘automatic’ mode starting with the boiler on it will work, move around and then turn off as it’s supposed to. The problem is that it won’t turn on again when it should!

Any ideas?

Thanks in advance for your help

Yep new integral timer. Is it the one with the little black pins. If so they always break.

Yes, it does have the little black pins...but only had a new one installed last week when the PCB had to be replaced anyway

I just wanted to check on here that I wasn’t missing something before I call the CH guy back!

Has it been set correctly? For on times and off times?
