I am in the process of building a new system 50 amp service. I found one of PJ's diagrams that is perfect but I would like to be able to use the BK pid to cycle one of the pumps on and off to maintain the mash temp by running it threw the HLT coil when not being used to boil. Using the temp probe in the MT sense it's not needed for the boil using manual mode
I believe this can be done by using 2-3 position switches, the first on the positive out put lead of the pid switching it either to the pump ssr or the Bk ssr.
pos. 1 (left) pump, pos. (switching on the pump ssr pid contorled) 2 (center)off, pos. 3(right) BK element ssr.
The second 3 pos. switch would run the pump -
pos. 1(left) pid controlled pump, pos. 2(center) off, pos. 3(right)manual pump on.
It looks like I would just need to add another ssr to apply the power to the pump when being controlled by the pid that would be switch to via the first 3 pos. switch. Hope this makes sense
and thanks for any input
