Im sure this has already been addressed, but has anyone ever used these to control asco/solenoid valves on a brutus?

I'm using two of the fahrenheit single stage units to control the pump and furnace valve on my HERMS. They were quite a bit cheaper than the STC-1000's, and I don't need dual stage for this application. They also have SS probes which is a bonus IMO. Here's what they look like mounted in my ghetto control panel.

So I may just have the fan running all the time... or, I guess I could deal with a relay at some point so it'll only run when the heating or cooling relays are on.
I think the latter may still give the same problem as I have now though.

One thing to note though is that I still have the temp probe in free air, so it's probably affecting the differential a lot more than it will when I finally get it measuring some fermenting wort.

I have a fan primarily to deal with condensation, so during cooling is the most important part.

I think you're definitely on to something.
I just plugged the fan in and am leaving it on all the time and it's already made a huge difference.

So here's the mostly finished product. Using a 4x4x4 box from Lowes.
I have a blue neon lamp to replace the amber one on it's way.. amber and red don't look a whole lot different when they're lit up!

krazydave, can you share your method of wiring in the different temp probe. I guess what I am reluctant to say is "can i see inside your box"?

It wires in the same as any temp probe, he just wired it onto a headphone connector. I was actually going to do the same once all my stuff got here.

Yeah, it's just a 1/8" mono headphone jack.
I did have to take a larger drillbit on the inside and thin it out enough for me to get the locking ring on the outside though.
I'm just a little anal about how things look, so I didn't want to just drill a hole and run a wire through.

Did you use a decora receptacle on the bottom? I've been looking for a way to keep it lower profile than using wall plates, and I've been looking for some sort of female panel mount receptacle, but can't really find any.

My only concern with using decora outlets is that unless the hole you cut is *perfect*, it's going to look like crap.
