Testing ARPrvSafe and Fridge operation
I installed the ARP controller in my MH. The install instructions were straight forward and easy to follow. It takes a good 2 hours to install. Here's what you get. The controller is mount...

Answering questions.
Ambient temperature when starting the test at 9am was 53 degF. That was the boiler tube temperature recorded by the ARP unit.
I had the fridge on the "warmest" temperature setting: "1". It would have been great to also record the fridge food section temperature, but it didn't occur to me at that time.
This test was with propane. It should work the same with 120V ac.
I believe the data has tab separated values. The data goes directly into an Excel file. I screwed up my Excel file by initially choosing the newer version of Excel which I didn't have. This caused all sorts of errors when I looked at the file. The ARP package comes with two versions of a Excel files containing macros to acquire the data and do what ever else it does. I don't know what it does as my "operator error" prevented this from happening. I saved the unusable file into a txt file and then imported this data into my version of Excel. Temperature is measured every 2 seconds. That's a lot of data when recording for 6 hours.
I had to purchase the data cable from Digikey for $20. It would have been nice to have a standard USB connector on the ARP unit. It does not. I have seen a photo of a ARP controller with a mini USB connector. I think Paul, the person who sells/designed the controller, envisions everybody purchasing the ARP controller that does not have the data out stream feature. You can also push the display button on the controller to display current boiler temperature on all units.
I plan to do more testing the following weeks while in Baja. If I get a chance, I'll see how off-level affects boiler tube temperature.
