Thanks all for your help / replies! @passedpawn, in your diagram, my understanding is you are switching the hot inputs and my ground and neutral (which is not shown) come into my pump externally / outside of the relay. Being new to relays, is it okay that the two hots could be energized at...

I am going for efficiency as much as possible in my design. I have read a ton of schools of thought on this - but won't recirculating the pump only when needed to lower the temp of the coolant be sufficient enough? I am thinking about going with an external self-priming pump vs a submersible...

The two inputs are 110v and the single output is also 110v. Couldn't I accomplish this with only two relays on the input side? If either input is switched on or both are switched on, the output or the pump in my case is energized. Edit: The diagram would look like this. Wouldn't this work...

I think I figured this out. I can use relays to do this.

I am designing a glycol chiller with a 5,000 BTU A/C unit. I would like to have only one pump with two relay temperature controllers (eg a Baylite controller). The first temperature controller will turn on a pump and the A/C unit only to recirculate the glycol until it reaches my set...

Got it, thanks for your response!

Hi all, New to electric brewing but not electricity. I am using Doug's diagram below on my build. The SW11's in this diagram are 120volt (not 240) correct? Just double checking - as the switches are taking in a neutral and hot on the lighted indicator but passing through two separated hots...
