Added the new wall wart to diagram and added a new wire color for the new 32v that comes out of it. Do I need to get a special relay that takes 32vDC for the coil? If so, might as well buy a 12v wall wart and use the 12vDC relay that I already have Also, I realized that the hot for my relay...

Jcos, not sure I am following what you are saying. Thanks Danb. I just bought a 145 piece connector set on Amazon. I think it included a crimp tool. If not, will get one. I have two wall wart power converters. I bought a new one for the fan because I couldn't find 12v It seems that the...

I started the build this weekend. Have most of the stuff installed into the toolbox and started the wiring. A few challenges remaining newbie question: I indicated a 15amp fuse, but they come in little cylinders. What device should I buy to properly wire it into the hot side? How to...

Sorry evanmars, not sure exactly how to read your diagram. Why do the SSR and CR1 show twice in the diagram? What is the significance of the two parallel lines on one of the SSR and CR1 items?

heh, I bought it a while back when I knew even less than I know now. Just looked it up and it appears to be this relay (not a transformer) which on the bright side does appear to be a DPDT though I think I am fine with the way I have daisy-chained the pushbuttons. How dare you make me go back...

Gotcha, so if I run a 14gauge wire from my ball valve to my brew tree (metal) that should work, right? I already have the 12vDC transformer so I might just use that for the float switch anyway even though bunch of people said not to worry about it. Not sure I want to deal with using the power...

OK, I think I am just about finished here. I looked up the specs for the pushbutton and figured out exactly how to wire. There is a separate wiring for the pushbutton light. The bad news is that it makes the diagram WAY more complex. The good news is that if someone buys the same stuff, they...

Thanks Kevin. For all the effort that I am putting in and you guys are putting in to help me, I want this to be valuable to people who come behind. I plan to write up a full report once I get through the build. So, making it readable is important. Is the below better? All pushbuttons now...

The SSR is going to be mounted into the side of the toolbox with the heat sink on the outside. I hear you about turning on the fan when powered, but I am getting fatigue with designing this circuit and so may do that as an upgrade if the box does appear to get hot. That does make sense, but...

Sorry, have clarified by splitting into two colors. The floatswitch circuit is using 22 gauge for 120v and the computer fan and PID have 22 gauge for other voltage. New diagram attached Is there a reason why my powering of the PID pushbutton from the closed Pump pushbutton won't do the...

Yes, both of the female plugs will be on the same circuit. I am inexperienced with wiring, but I am guessing that I will run the hot from where they come from elsewhere over to the second of the plugs and then back out to the overall system neutral. The incoming neutrals will be able to go...

Yeah I hear you, I have done the requisite reading about wort scorching, but here was my thinking..... I wanted to leave the opportunity to use the pump without the RIMS tube being on (possibly for recirculating water through a chiller). I felt that I could be smart enough to never turn on the...

The fan is because this circuit is installed in a tool box to make it portable. The pump has the liquid part on the outside and the motor on the inside. The RIMS tube is bolted to the back of box so that heater/thermoprobe leads can be run from holes drilled in the box. Pushbuttons and PID...

crossposted a bit. Yes, evanmars that looks like the right logical circuit for what I am trying to accomplish. Not sure about the voltage changes for the float switch and how it is powered. I posted a diagram that has a transformer and a relay, but might be overkill. Thoughts? rauliii here...

Idiot mistake. Yes. 29w 120v for the pump. I thought I read somewhere that it was 1.4amps, but 29/120 = .25amps Mechanical relay seems to make more sense for the float switch given that it won't switch as much as heater and is not drawing much power through the switch (I think that makes...

yes. Those are the specs on the product description It seems from the specs that they are. Specs even indicate that they can handle 240, but will be a little bit dimmer with 120 Thanks for that diagram. My goal for the middle pushbutton is power to pump when pressed as well as lit when...

Thanks so much for the responses. Sorry, haven't got all the terminology quite correct yet. Yes, I meant neutral rather than negative. I am thinking batteries that have + and -. Have added neutrals to the pushbuttons. I don't have the pushbuttons in front of me. How do they actually get...

I have been learning WAY more about electricity than I ever thought I would when I decided to take on this project..... I am building a RIMS tube that will attach to a toolbox and all the electrical stuff will go in the toolbox. 120vAC system. Will use 3 pushbuttons to run: PID/heater/RTD...

How do you convert the power on one of the plugs? Do you split the cable from the original power source and then run one of them through an SSR?

First of all Monster, I really appreciate you taking the time to reply. I haven't bought the float switch yet, but thinking I'll just get this one: http://www.amazon.com/dp/B000LDN6XE/?tag=skimlinks_replacement-20 Where is the RIMS heater on your diagram? I am planning to wire up the...
