Yes mate linked across terminals.
Could get continuity across spade bits on back but not on terminals on front, with stat turned up or down across either nc or no terminals
I've never worked on one of these before but that looks like a reset button in the middle of the big shiny nut!
Are you sure you are experienced enough to be able to work on these? unvented cylinders can be pretty dangerous things if you were to do something silly like bypass a safety stat and let them get too hot! And of course they do have their own rules and regulations surrounding them.
It's not the plumbers job to wire and connect the controls, it is yours. What would you do on a new house that you were wiring if plumber said Im installing upstairs and downstairs heating zones and an unvented cylinder (S Plan +), would you sub it out?I don't touch heating, pipes, stats, trvs, anything that involves plumbing or central heating, ts a plumbers job, not mine, I don't have a clew what I'm doing. I'll be open and honest, I have no experience of heating controls.
