The data logging will OPEN your eyes to what's really happening
Download the software from the ARP web site along with the many free documents. The controller outputs a data stream via a 5 or 6 pin in line connector, which I belive is a simple RS232 5Vdc data stream. I use an embedded micro processor conversion cable to get USB serial data to the rigs computer system. The controller outputs both a deliminated text file and two MS Excel formated data streams 2003 / 2007. Take a look at the supplied Excel templates which you can easily optimize for your unique situation.
A few degrees off level and **WOW** the temp climbs

The mechinical unit is closer to 5 bucks than 20, it is already on the market, several dozen versions of it, you just need to pick the right temp.. Disc Thermal Switches such as used on high-temp fans and such, i have 4 of them in this Motor home.. Alas, I have no clue as to the proper cut out temp.
I also like to keep it very level.

I'm very impressed with my ARP w/it's data logging capabilities
Logs temps every 2 seconds or so into an excel file - makes it very easy to really see what's happening regarding those temperatures under all conditions.
As stated it's not really a plug and play device.
Not worried about the hundred $'s or so which is less than a 1/2 of a tank of gasoline. My testing/data logging of on-level & off-level operation opened my eyes to the actual temps.

I have a wire bundle that travelled up the wall near the top of the flue tube. The insulation outer layer was burned off a 120.v wire. The back of the fridge had burn marks near the top of the tube. So, do they get hot, you bet they do. Until you design and market this simple $20 mechanical limit, this product worked for me. I don't mind paying some extra money for safety.
How many refrigerators fail due to an overheated boiler ??? Not guesses, not estimates, but facts?
Appears to be a severely over-engineered product for its use; a simple high limit control is all this appears to be. If something like this is needed, a simple $20 mechanical limit would do the job just fine.
I'll keep my $120 thank you.
