Congratulations on the awesome build! I am currently in the "slowly amass bits a pieces" stage of a similar minded system (mash in separate vessel, vis-a-vis jkarp's countertop brutus
) and since P-J is on a role with the
wiring diagrams, I figure I'll try my luck at a blessing as well!
As far as the electronics are concerned, everything would be the same minus the element power leg of the controls. (And using the Auber SYL-2362
, but I dont think that changes anything)
I am wondering about the contactor used to switch the element's power. If the system was dedicated to 120V, would this Auber mini relay
work for a 2000W element? Secondary to that question, I am planning a little addition on this build's control however. I would like to throw a horizontal float switch
into the kettle to prevent dry firing should recirculation become poor and the kettle level drops. Because it has a low amperage switching capacity, I'm assuming it would have to connect to the coil of the relay/contactor. That said, I don't want the float switch to always have control, queue the three position switch!
; Such that I can have element power off (says me regardless of anything else on the system), on/off (says the float), or on (says me regardless of float position).
To further complicate things, I am uncontrollably reverting back to my PC-mod days and really would like to have small panel mount LED indicators
for things like system power, pump power, element power, and of course water level (do I smell a bicolor high low LED?). Unfortunately and shamefully, I have lost my electrical know-how since those days
. I'm guessing the drastic change in amperage and voltage will require dusting off the breadboard and making a small project board that interfaces with the status of the control's switches/buttons to feed the diodes.
I would love to start a thread about this build once it gets a little momentum in the physical world. Any help to get the control portion materialized would be great! Thanks everyone, and again congrats on the successful build.
