Controller wiring diagram
Posted: Mon Sep 21, 2015 6:21 pm
Can one of you more electrically savvy membera take a look at my wiring diagram for the 240v controller I plan on building? The idea is basically a K-RIMS like the breweasy, but at a much lower price point and using my existing coolers and kettle. I want to control one element with one SSR and two controllers. One is a PID and the other is basically a PWM with knob and digital display. A three position switch will determine which controller is in use. The switch will control the 120v relay coil leads and the positive control leads from the controllers. My biggest concern is bridging all of the neutral control leads and only switching the positive. I think there could be some cross talk with this. I could add an additional pair of NO blocks to the switch, but I want to try to keep this as compact as possible and already have the two block pairs on there.
I also have two pumps in there too. The first pump is for wort and I have been toying with keying the PID control to that so I don't fire the element without recirculation. I don't think this is a big deal overall as the element would be in the kettle not the grains. The second pump is for icebath recirculation.
I don't have an alarm, but I am edging towards adding one. I like the idea of setting the PID to the strike temp and just below boil temp and walking away. I don't like the idea of the alarm constantly going off and don't care to add an extra switch just for the alarm. Are there any alarms with an integral on/off switch? I looked around and didn't find anything, but figure I would ask. My second though is to mount an alarm inside the enclosure with a switch on the panel. This would keep the panel a bit more tidy.
