Controller is finished and functioning as expected! My only question is heat sink temps. I’m running a water test right now in anticipation for tomorrow’s brew day, and starting with 46 degree water, my element has been running over an hour heating the water up. Duty cycle is running 100% so...

Thanks as always doug! Makes much more sense! Everything else is functioning properly except for the dead SSR, so i ordered a new one and should be here tuesday. Once its replaced i'm going to fire the system up and do an auto tune ahead of a brew day. Will report back!

Ok the more i read, without the actual element plugged in, the voltage leaking is going all to the lamp. With the element plugged in, it acts as a capacitor almost and the leaking voltage doesnt affect the light, but also shouldnt energize the element enough where it makes a difference. Just...

Never ends So as i'm putting this together, i'm like 98% done, and now in the testing phase and i'm finding a few issues with the SSRs 1) I'm getting 16-18volts coming through the contactor to the output legs if the switch is turned to the on position for that particular element, when the...

Just finishing building my plastic enclosure controller as well. A ground bar is fine for central grounding since theres no conductivity with the enclosure. Just have the power in's ground connect to the ground bus bar, and then everything else that needs to be grounded should tie back to that bar

Yeah those look like tandem 20amp breakers in a single pole 120v circuit space. Ie: 4x 20amp 120v circuits in 2x 120v circuit spaces. Used when your box is overloaded and you need space usually If that’s what’s being used to connect together to build a 240v circuit, then there’s a bigger problem

Actually if this is what you mean, totally makes sense. I wasn’t thinking of the light Block as it’s own circuit. Pulls the switched power off the out of the hot side block from the switch, neutral to the other side to complete the circuit for the light

Confused a little bit. What do you mean by “The other X terminal is usually connected to the switched side of the contact pair.” do you mean 120v hot goes to 3, 4 goes out to the destination, neutral goes to x1, and x2 gets jumpered to 4?

One last question. I broke out my multimeter last night to test the switches to ensure i'm clear on what connectors are what, but i want to make sure i'm clear on lighted switches At the bottom on lighted latching NO rotary switches, i see two blocks. Tested with my multimeter, one block (3...

Yeah i'm a big fan of neat and tidy so i like having terminal blocks and bus bars where i can. Approval given by doug, good enough for me! I'll post the build when all of the parts are here :)

Revised based on what i mentioned above. Wired the 12awg directly to the SSRs, powered the hot bus through a 7awg fuse (i might even reduce down to 4 or 5amps) on 16awg supply line, and then 16awg out to the pumps, contactor coil wiring, lights, and PID power. Will use 20awg wiring for things...

Thanks Doug! 1) I thought the SSR goes back to the PID, but i realize i misread one of Kal's diagrams and forgot i was looking at the contactor, not the PID. Noted. Send and return for the signal for the SSR both come from and to the PID. Got it 2) So wouldn't it make more sense to just bypass...

And for another check, should i pass the incoming Neutral through the 2nd pole on the startup contactor? Or is it redundant and unnecessary. While i dont see myself moving to 240v any time soon, i'm building this panel because it will suit my needs at 120v, and can be retrofitted eventually if...

Pulled the trigger finally on building my 3v 120v brewing controller. I've been using a hacked up inkbird IPB for over 2 years and its finally time to build something where i'm not constantly moving cables and wires, and can handle a full 20amps. Basically a stripped own version of the...

I’m currently on year 2.5 of the cereal killer and it hasn’t skipped a beat

If o2 contamination is a concern in the serving lines, what are major breweries using? They absolutely cant be unhooking their lines every single day and rehooking them back up. Their downtime i'm sure is no different than the rest of us. Some breweries are only open Th-Su, so their lines...

I leave both gas and serving lines connected, so i'm giving the EVABarrier lines a try to see if they help in mitigation. If i still have issues, i'll try disconnecting when not in use. I dont see anywhere in my packaging that i could be picking up any appreciable oxygen since i purge...

Personally I don’t get how o2 could permeate into a gas line under 12psi or pressure. Serving lines I get. But I just don’t see how positive pressure would allow o2 ingress

I'm overdue for changing my beverage lines, so i just ordered EVABarrier tubing to see if that makes a difference

To all those who brew successful NEIPAs and keg them, what's your typical shelf life in your keg? How long do they stay bright and citrusy before degrading and taking on more of a malt forward flavor? Just curious to see what everyone else's experience is compared to mine assuming proper...
