Hi to all,
I have a 21m boat and want to run a 220 Volt Ac circulation pump for a solar hot water system with adjustable on and off times. 1 min on and 20 min off would be fine. Supply can be either 12 or 24 Volt DC. How can I build such a thing?
Thank you in advance,
Bernd Keller
hi,
thank you. I agree but I just need to activate a relais for 1 minute and then after 30 minutes again for 1 minute and so on. where can I find a wiring diagram that tells me the sizes of components?
