This has two pumps, but you can just leave out the switch and outlet for one of them. If you don't want the external alarm, you can use the DSPR120 instead of the DSPR300 (both are EZBoil controllers.) Substitute DIN contactors for the non-din contactors specified on the drawing. You can also substitute DIN breakers for the fuses if you wish. It also implements an interlock scheme that prevents the power from being turned on if a pump or element power switch is on.
Note that rather than SW1 switches that are 2NO, you really need to use SW11 which are 1NO/1NC if you want to implement the interlock.

doug293cz, I was wondering if you already had a diagram setup like this, but for 20A, 120V? My outlet is 15A, but I would like to setup the controller box to support 20A.
I really like the layout of your diagrams, and I am looking to do a RIMS setup soon.
I already have the TopsFlo TD5 pump, which is rated at 24V, 1.4A, and 35W. I would most likely get either a 1500W, 120V, 12.5A element, or get the 5500W 240, but run it at 120V for 1400W at 11.7A.
I planned on a similar design as the one I quoted, just not 30A or 2 pumps. If you have one that already has 2 pumps, I have no issue using that as it is easy enough to figure out what to leave out.
I just want to make sure I have everything straight for what to purchase, and what should be setup with a fuse. I am pretty sure I know, and I would really appreciate your help \ feedback.
I searched and could not find anything that you posted that was similar except for the 30A layout.
Thanks for any help you can provide, and for the help that you provide this community!!!
