Came across a Heatrae Sadia hot water cylinder in my travels and was intrigued as to why the single phase supply was wired through two stats before going to the element terminal.
Enquired with a colleague who said one stat is used for temperature cut out and the other for temperature regulation. That's fine I thought, but both stats have a manual temperature dial on them, which seems wrong. Surely the intention is to wire a dedicated temp cutout as well as the adjustable temp control stat, not two temp control stats.
I was advised to set one at maximum temp for the cutout and the other set at the desired tap point temp, either one or the other, it shouldn't matter.
So my question is, if I've got one stat set at say 80 degrees and the other set at 40-50 degrees, how is the desired 40-50 degrees regonised and not instead the 80 degrees?!
