Manual mode is just to put your mind at ease. So if your computer crashes or something along those lines, you can switch to manual mode to maintain temps until you can get the BCS back up and running again. Although I haven't heard any reviews of the BCS crashing, at least you can be prepared if it does.

That makes sense. I guess I was assuming that most people who included a manual option with the BCS were doing it to allow full manual control (including element regulation) in case they felt like it.

The BCS requires the computer to be up and running to get the brewing process going. Sometimes when I setup, I get the water in the HLT - get my control panel hooked up and the BCS hooked up to that (to provide the 5V control signal) and then just turn on the HLT element. That way, I'm heating water while I continue setting the computer up - bringing up my brewing recipe software, etc. Gets me a head start on heating the water up. To be honest, I don't use the manual on the elements much more than that. The pumps and stir motor I use the manual switch all the time as I find it easier/more satisfying to just turn my pump on with an actual switch than with a mouse click.

with some fermcap I could brew in full manual...I'd have a really high boil off rate with the elements at 100%, but I could account for that.

Hey - Any recommendations on where to get the Contactor from? Also, what is the difference between a contactor and a DPDT relay?... are they the same thing?

I'm curious - You quote an entry Originally Posted by Bsquared - however the diagram is one that is completely different than the one he posted. How did you do that??? Your quoted diagrams show the use of 240V pumps. Is that what you will be doing?
Here is another diagram that might fit your needs a little better:
Please note that I have changed the switches to illuminated units. Switch 7 is used to limit power delivery to one or the other element.

Follow-up on the above question in this schematic. What is the difference between a contactor and a DPDT relay? Benefits to using one vs the other?
Also, where is a good place to purchase from?
Please let me know. |

Good job, you are right on the money there. |
