Anyone got any experience with electrics? In particular hot water cylinders and an auto switch on a fuse box?
We have a hot water cylinder, and on the fuse box is a simple fuse switch, with ON, AUTO and OFF. (This: https://elec44.fr/contacteur/6844-legrand-contacteur-domestique-silencieux-230-v-2p-250-v25-a-2-f-ref-412501-3245064125017.html?gclid=EAIaIQobChMIhIK4ifzM5wIVlOFRCh2TGAhtEAQYASABEgKx_fD_BwE#ectrans=1)
However, since having a power cut, this doesn’t seem to be working on auto. If we set it to auto, our hot water runs out after a day… as if it’s not switching on when it should. It’s fine when “ON”, so it’s something to do with the timer I guess.
I’m guessing it’s supposed to switch on at set times when it’s cheaper rate. What I can’t work out is how it knows… I was expecting to see a timer, or a clock or something - that I suspect has been reset… but I can’t find it. Do you know if the fuse box would have a clock/timer inside it? Or do these switches work in a different way?
I’d appreciate any help you could offer!
