Dan, I'll cross-post to the forum at http://stlbrews.org . Also looks like I'm going to have the Tech Topic at the Feb meeting.

P-J,

Switch #5 - that's a DPDT switch, right? That allows the pump to continue to run while interlocking the power to the control circuit for the RIMS element? I'm fairly certain of that, but need to doublecheck before ordering parts.

On second thought - the switches from Auber indicate there are 2 sets of contacts. So nothing to worry about?

Thanks!

Can't wait to sede how this works out!

The switches are from Auber Instruments.
Illuminated Pushbutton Switch
They are available in 3 colors and have 2 N/O contacts. That makes them a DPST unit.

Yes, switch #5 is interlocked so that RIMS pump power is supplied whenever the RIMS element power is applied.

Hope this helps.

P-J,

Auber came out with a new PID that has an integrated timer.

1/16 DIN PID Temperature Controller w/ Timer [SWA-24X1] - $57.50 : auberins.com, Temperature control solutions for home and industry

It seems pretty much like a 2352 except there is a timer reset and 1 alarm.

Do you think this would integrate pretty easily? I would have to add 1 switch to reset the timer.

Thanks!

Yes that certainly can be done. You would need to get the PID Model SWA-2451 so that you have SSR output control. (Model SWA-2441 is relay output) You would only need to have one of them as well.

Thanks P-J. I'm going to alter my parts list to include this PID/Timer instead of the 2352's. I'll have one for the RIMs and one for the BK.

Scored a Stahlin enclosure! It's roughly 17"x20"x10". Fiberglass and the price was right - FREE!



I also got a couple of heat sinks for the Crydom SSR's I'm using.

Next up - PID/Timers, RTD's, contactors, & switches from Auber. Unless someone knows of an illuminated, maintained switch for less than $11.98.

Breakers from either ebay, Pioneer Breaker, Factorymation, or Automation Direct. These buggers are pricey.

Then I need plugs and receptacles and get the electrician in here to wire up my subpanel that I need to buy....

Finally starting to make some progress on this project.

The holes on the front where the wrong size and location so I filled them up with some Bondo and sanded them nice and smooth.



The four holes around the perimeter of the door are for the door latches.

Now that the holes are filled, I'm trying to determine the best layout for the controls.



From left to right and top to bottom,

HLT PID, then RIMS PID with Alarm for mash complete timer, and then BK PID with alarm for hop additions timer.

Pushbutton maintained switches (green) in the next row down to control the contactors for the heating elements.

Pushbutton maintained switches (white squares now, but maybe yellow pushbutton switches) below the RIMS and BK PIDs for resetting the timers.

Then on the bottom row the pushbutton maintained switches (blue) for the pumps. RIMS on the left and CFC on the right.

The PIDs for the RIMS and BK are the new SWA-2451's from Auber. They have an integrated timer in them. They are set so when the temp of the wort reaches the set point the timer starts to count down, regardless of the temp. When the timer expires the heat is cut and the alarm will sound. The timer requires an NC circuit, so to reset the timer and alarm the switch is turned off (open circuit) and then back on. It's only a single stage timer so it should work very well for the RIMS and ok for the BK. I'll just have to set the times correctly for the hops additions.

No holes are punched yet for these controls. I haven't decided if I should switch the row of element switches with the row of timer reset switches. What do you think? I'm open to ideas and discussing with you guys will help me think through it.
