Heating timer replacement

[Link65]

I'm trying to replace an old Landys and Gyr RWB2 heating & hot water timer with a Horstmann 425 Tiara.

I'm just a bit perplexed as to the wiring - I've looked and the wiring diagram for the old timer and tried to convert it to the new 'tiara' timer.

But it looks totally wrong.

Can someone have a look and see if they can spot what I've done wrong? Heating timers are not my forte.

Edit: Just for the record, that's not my shoddy wiring.

That is truly horrendous, earth as a live cable and identification

Yeah, I didn't install this. but it's making identification difficult at best.

Too right it does, have you a pic of the wiring diagram on back of original timeclock

Here's the original clock should be the same diagram as the upload on the first post.

I see the cpchas been used as a control conductor, not a good idea.

You would be better advised to get an Electrician in to sort the cable out and connect the controller up for you, advising someone via email and pictures is not a good idea really.
