Thanks all - really appreciate the info (and effort of those involved). It is now wired up as in the diagram above, and appears to be functioning correctly. I guess (since I have a modern stat in there now) it is now extra-double protected against boiling, with two thermal cut-outs as well as the main stat (one in the stat plus the old one). No harm in that I suppose, so I shall leave it as it is.

No it isn't, it's a NON self resetting termal cutout. You have to press the button in the middle, which is presumably what you've done without realising it.the outlaw said:
All new thermostats have them built in, with a very small button, so the original is redundant.
It would have been worth looking at the FAQs.
The original should have been wired like this:
I did mean a self resetting cut out as in DIY not the component resetting itself, the reason I said to bypass it was to see if it was working at all.

Ah another Tony, well it was nice of you to chip in after all is done with wise words, well done.
The bypass was to check it was all working and you have no idea what was said on the phone or cant you read very well???
Before you critisise read the whole thread please and check facts too.

Perhaps you used to advise students to "bypass" safety components!
However, I consider that it is potentially dangerous bypassing components.
I teach my students how to use a multimeter to test components!
