I like your idea.
There is no probe on the transmitter. It's wireless as in RF. The transmitter is in a plastic zip lok bag floating on top of the beer. The only thing separating the beer from the transmitter is the wall of the thin plastic bag. I have a muffin fan running continuously in the freezer, so the entire keg should be of fairly uniform temperature, even at the surface. Close enough for me in any case. I have indoor/outdoor thermometers in all of my refrigerators and freezers. I like the min/max memory feature they have.

I got all my parts in from keg connection yesterday and I am going to install everything tonight, does it matter what the length of my hoses are for the co2 and beer line? I was just thinking about cutting enough hose to go from each connection plus enough slack on each connection so that if I need to move things around in any direction, I can. Is there anything else to take into consideration that would make me want to cut my lines longer or shorter?

The gas lines just need to be long enough so you can maneuver them and/or around them comfortably.

The beer line length does make a difference. Mine are six feet. That works well for me.

Here is a table of volume of C02 at different temperatures and line lengths

You know what i don't understand, I know they make a faucet that attaches directly to the liquid out disconnect that is attached a soda keg. There is no hose attached to it. How do they get it to work well?

Last night I hooked up my first keg and poured a glass. I first set it to 5 PSI and it came out nice but a little slow. Then i kicked it up to 10psi and it came out nice but a little faster. I really don't think anyone needs those charts because all you have to do is experiment. Those charts are most likely really useful for people who install draught systems that are rather large and where the kegs are stored a long distance from the faucets.

If it is a code type regulation, I would think that it could be located somewhere.. Industrial groups would likely automatically reject the idea on the basis that it lacks flexibility.

3. Yes, small relays can be set up to operate larger relays. No surprise there. These controllers are nothing more than digital thermostats with a built in relay that handles line voltage. Some have more features than others, but they are still just simple digital temperature switches.
Hmm. Well, there is the possibility that I am wrong about this. I will check my controller again. My information is all hearsay, so I cannot say for sure.

I searched the web a little and I came up with a few items. This page says that the delay protects the compressor after a power outage (read 3rd paragraph).

This PDF page talks about power outage protection for the compressor also (1st paragraph).

This temperature controller information page says "Automatic Delay Restart (ADR)
Auto restart delay: Ensures on line quality after power failure, decreases power loading, and protects the compressor."

I think my information was basically correct, except for the "requirement" part.

I thought you said that you use a Love controller (or Ranco or Johnson) and that they had a built in default delay, so it should be easy for you to check.

The first link is completely irrelevant to our discussion. That link lists some high tech $16,000 freezers. Who the hell owns one of those anyway?

Can't open the second link, but also irrelevant. Most of the controllers have an adjustable parameter for anti-short cycle delay among others. We are talking about a mandated built in unavoidable start up delay.

The third link shows another obscure temperature controller similar to the Love's I guess. I did not bother to read the specs all the way through, but it looks similar. Again, nothing new here and nothing that isn't addressed by adjustable parameters on the Love's, Johnson & Ranco's.

It's not important. I was only curious about the non-existent regulation regarding start up delays built into these timers. I think I have the answer now. Thanks for your trouble anyway. That must have been a lot of work.

Anyone ever mount a Johnson A419 inside of the keezer? It's kinda bulky, and I'd like to get it out of the way....

I have designed a lot of things that get plugged into the walls in a lot of countries.

There are some horrible requirements if it is medical equipment. They don't want the patient getting shocked.
Military has EMP for when atomic bombs go off in the upper atmosphere, and TEMPEST requirements so the Russians can't tell what key was hit on an IMB Selectric typewriter.

There are some double insulation requirements that kick in to get a UL sticker, and sell the stuff.

But home brew electronics has one big requirement, not to put power back on the line during a power outage. They don't want line men getting electrocuted by your windmill.
