Pipe stat operation/wiring

    Not sure if my pipe stat is knackered. The connections make contact when i turn the stat above the current temp (or close depending how its wired). I would have thought the wiring contacts wouldn't close until it reaches whatever I have it set to?

    I want it to make contact when water temp reaches 80 degrees, but as soon as I move the dial above its current temp they make contact. I don't see the point in having a set point if its always on above current.

    Am I missing something or is it knackered?

    You've wired it backwards. Live in - common ( C )
    Live out - depends on the stat. Either 1 or 2. When you turn the stat down it should power the pump. I'm assuming your talking about a pipe stat for a solid fuel boiler

    It only has 1,2 & 3. No common. I have live into 1. I'd tried every variation but it just seems to make contact when I turn the dial over the current temp. It clicks (as you would expect) then the contacts are made. The whole setpoint seems irrelevant.

    1 would normally be common, 2 would be NO, 3 would be NC

    Common (live feed) to 1
    Call wire to 2, would mean call when temp is reached/breached (bring on a pump etc.)
    Call wire to 3, would mean call UNTIL temp is reached/breached (bring on a boiler to heat system etc.)

    'Buy cheap buy twice'. I bought a new one and it works fine. My own fault for buying cheap ****. The old stat was 12 quid and is just a bar that bends with heat to trip microswitch, new one was 14 and has a proper capillary tube. Accuracy of old one must be way off by its design.

    Thanks for help folks.
