Evening gents (and ladies)
I was doing an S-plan boiler house setup this week and after I had done it, I started to think about the flow of electricity to the point of insanity.
Imagine in the S-plan setup, a 2 chanel controller, controlling a cylinder stat and a high limit stat.
The cylinder stat controls the CH and the high limit controls the HW.
Now, when a person presses the CH button on the controller, the current flows through the cylinder stat, to the CH valve, when this valve is open a switched live from it is sent to the boiler and external pump.
Everything is fine so far, if the person presses the HW button on the controller, the current flows through the high limit stat, to the HW valve, when the HW valve is open, a switched live is sent to the boiler and exernal pump.
Now here is where I am being stupid .
When BOTH the CH and HW buttons at the controller are presses at the same time, both valves will open, and BOTH valves will send a switched live to the boiler. Does this not create 400v?? two phases together??
I may be just missing a simple explanationView attachment Sundial-S-Plan-Reference-Guide.pdfView attachment Sundial-Wiring-Rev1d-2nd Edition.pdf
I have provided the diagram
Thanks in advance
