Looks like a nice unit!

Do you have a version that can handle an AC pump?

Its got 10A output relays that should work for that applications. I would keep the pump below 4-5A for AC version and would probably advise to put a MOV in parallel with the relay contacts. You always connect an external contactor to the unit if you wanted something beefier.

That looks like a DC switch to me since its for cars maybe. You would probably be better off with the 10A relay contact unless your load is DC.

This gizmo works great on a taco 009 taco pump 120v@1.2A controlled by 3.3v I/O pin.

Hi to all. I have made free Arduino's solar controller. I am from Ukraine and tried to translate all instruction. Maybe translation was done not so good but i was trying. I think now, everybody may to do thermal differential controller by yourself!

Of-course i cannot post links for now... Also i have interesting online monitor page of my home-made hot water solar system, but it is not in english. I may try to translate it too.

Now i am working in this direction. For example i plan in few next month to release new firmware (cost $4.95) with WEB Monitor function, so everyone will be able to have similar monitor.
But this WEB-monitor needs a separate web-server to work, so i am going to provide my own web server with $0.95 per month or $9.95 per year. And of course - the same firmware for hot water solar controller is and will be free (without web-monitor function)
