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?
