I have a huge spool of thermocouple wire. If anybody is looking at automating their brewery and needs some thermocouple wire, let me know. I will send you a chunk for the cost of postage (yes, I have _that_ much)

right.. timers are removed. I was just thinking/typing out loud trying to figure out how I wanted to set the thing up.
gonna try to finish it up tonight and do a test brew this weekend.
nothing else in the system will have changed.. just means that I don't have to control the pump by unplugging it any more.

only real things missing from the panel are blinky lights & stuff..  after I clean up the wiring to make some room, I'm going to add some.. just for fun

welp.. I took the timers out..  the SSR for the watlow is connected through the pump's power switch so the heater can not be on unless the pump is on.. seems to work.. will do some functional testing this weekend

Equipment and Software / RIMS control panel
« on: August 03, 2010, 10:04:24 AM »
I'm building a new control panel for my RIMS setup. A friend gave me an old control panel he removed from a plant. It has a 30 amp contactor in it, 2 power switches and 2 60minute timers.
I'm thinking about removing the timers and replacing with my Watlow temp controllers but wanted to get some feedback from others to see if anybody has any suggestions. I've thought about leaving a timer in place for the mash pump. That way (so my thought-process went) I could set the timer to say 30 minutes and go about the rest of my work. When the pump turns off, check for conversion.. then reset pump to another 30 minutes (or whatever) and let it continue.
The only thing I'm somewhat concerned with is having the PID controller turn the heater on when the pump is not running.. although I could set the pump AND heater on the same timer.. so that when the pump turns off, the heater turns off..

hmmm.. sounds like a plan.
any thoughts or suggestions?

TIA
Paul

oops.. sorry this is late, I haven't been on the forums in ages and had to register a new account.
the post from Real Beer is mine.
What you can do is de-solder the thermistor from the circuit board inside the temp controller, solder in a bit of wire to the board, then solder the thermistor to the end of the wire. This, in effect, makes the setup remote sensing.
What I did with the last one I built was put the whole thing inside an 2-gang outlet box. Then I used a wall plate with 1 outlet and 1 switch to cover the box, with an outlet on one side. Then I mounted the temp controller on the wall plate over the spot where the switch would be.
makes a nice compact unit.
The really nice thing for me at least is that since my kegerator is in my barn, I can unplug the freezer, plug in a small heater and switch the temp controller from 'cool' to 'heat' and continue using it in the winter
