So, I've been trolling the Electric Brewing forum for the last month or so contemplating various builds and have really enjoyed seeing all the different approaches people have taken. I feel fairly confident that I could make do with some of the wiring diagrams P-J and others have put out there, but if anyone is willing to tackle a specific design for me, I'd appreciate it!
My concept is a compact (toolbox or auber enclosure sized), portable controller that I can switch between brewing and smoking applications. I brew 5 gal no-sparge BIAB, so my starting volumes are in the 8-9 gal range, which gives me around 7.5 gal boil volume. I'd like to run 2-2000W elements on separate 20A circuits. One should be controlled by a PID/SSR, the other I want to be simple on/off. 1 pump for recirc & transfer. E-stop to kill it all via GFCI trip.
Here's how I see a brew day going:
1. Connect 2 extension cords to controller power inlets from 2 GFCI 20A 110v circuits
2. Connect 2 elements, pump, and RTD sensor to controller outlets
3. Energize PID-driven element and manual element
4. -5 deg from strike temp, secure manual element
6. Dough in, energize recirc and allow PID element to maintain mash temp
7. Raise to mash-out via PID element
8. Lift/drain bag, switch PID element to PWM, energize manual element
9. Achieve boil, secure manual element, maintain boil via PID/PWM element.
10. Gravity drain or pump to no-chill cube or fermenter
Controller should have:
2x 20A 110v inlets
3x control switches (PID-element, manual element, pump)
2x 20A 110v outlets (elements)
1x ?A 110v outlet (pump)
1x RTD sensor connection
The Catch - I'd like to use the PID-element outlet from the controller, plug in a smoker fan and take advantage of the PID for overnight cooks. Basically, connect a separate RTD, plug in the fan, set the temp, and walk away. Fan controls airflow to the coal bed to regulate heat.
So - Is that reasonable? Or would I need a switch and 4th outlet? Between the SSR and the PID? After the SSR?
Thanks in advance for any help or advice!
