Hi,

I recently built the AuberCube2 from a kit and would like to now add a float switch to stop the recirculation pump from running once it hits a level just above my heating element.

My setup is a 2vessel Kettle-RIMs with the heating element in the boil kettle, recirculating into the mash tun. The float switch will shut off the pump running recirculation when the boil kettle drops too low to protect the heating element.

I plan on using these parts:
Float Switch - https://www.auberins.com/index.php?main_page=product_info&cPath=69_32&products_id=339
Mini Relay - https://www.auberins.com/index.php?main_page=product_info&cPath=2_31&products_id=250

Mounted in a project box that will plug into the AuberCube (providing cube control, as well as GFCI from the breaker and that fuse built into the cube).

Here is how I plan to build it, can anyone chime in if this looks correct, or if I need to add anything else?

Why can't you just loop the FSW2 to the positive input signal of SSR?

Thanks, so with this option I would crimp the switch positive directly onto the line input of the relay? https://photos.app.goo.gl/vcHjo5nfFdfyLH5b6

No, what I mean is you do not need to use the R30A mini relay. Just use the SSR from the existing kit.

Do series wiring for the float switch between the controller output to the SSR input positive.

Got it, I understand now. That would simplify things greatly. I could just punch a hole in the enclosure for the switch adapter and not even need a project box.

After some additional thought i need to go back to my original external design. The relative height of the port i am using for the float switch requires that i have it positioned upwards, so i will need to use the NC output on the relay as opposed to the NO configuration of the Cube relays and toggles.

Does the original external design work, even though it is a bit more involved than integrating it into the cube?

If the relative height of your port requires you to installed the FSW2 upwards, you can consider using FSW3.

Also, you can use the R30A mini relay and do the wiring as your original plan, the output connector comes with R30A (sold by Auber) can only works with 14 - 16 AWG wire (up to 15 Amp load). To use the UL Listed R30A mini relay to drive a 5500 watt element, please get some bigger connectors for 10 AWG wire (30Amp load).
