Hi,
I'm in the middle of a campervan conversion project and am looking for some advice on how to wire relays.
I have a kitchen unit sink with hot/cold micro switch, a shower/wash basin tap with hot/cold micro switch, a toilet with flush/refill micro switch. I also have an external shower that is not micro switched. I will have a standalone switch for that. Hot water will be supplied from a water heater (propex malaga 5e) so I'm guessing hot water tap would trigger water pump, that feeds water heater and runs hot water to the hot taps.
Can anyone advise how I should wire this setup? Relay switches wired in serial? Any help appreciated.
Thanks,
Tom
