Temp Controller RNR, SNR what do they mean?

[Dave, I can't do that]

Hi All,

I am wanting to build a small 110vac temp controller for sous vide cooking. Found a bunch of PID controllers for around 20-bucks and lots of how-to-build instructions.

RNR, SNR and SSR?

I am guessing SSR is Solid Sate Relay, but what are SNR and RNR?

Search as I might I cannot find an explanation for those two. I see a zillion ads offering either type but have no idea which one I want.

Thanks

Dave

How do those links answer my question. Building the Sous Vide is the simple part and I don't need instructions for that.

Lead, follow or get out of the way.

Of all the links, did any one of them use anything other than a SSR ?

Sorry to waste your time, I won't do it again.

For example, the number for model TA4-RNR indicates that the first output is

a relay; the second output is None; and the third (Aux) output is a relay.

Dave M, thanks very much. That explains it nicely for me. Very much appreciated the detail you went to.
