Why are both frost stat and pipe stat needed?

Does terminal 4 actually have a screw and clamp - the drawings in the instructions don't show them?

Yes. Forgot to mention. Only the terminal number 4 is shown on the diagrams, though my frost stat also has a screw and clamp on T4 too.

If there is a screw and clamp and no continuity to any other terminal, your wiring scheme would work.

Thanks very much for your prompt and helpful response. As usual Mr Hailsham :)

Terminal 4 provides a circuit when the room is over temp, it's a 2 way switch i.e. the opposite to terminal 3.
Junction block it is.
