Cavagna Automatic LP Regulator

[Trevor43]

Does anybody have the Cavagna auto changeover regulator on their camper?......what does the changeover do once it has changed over.....does the red buttons pop out into the open hole on the dial?

the center dot changes color to match the tank in use

I have no center dot.......let me find a pic of the regulator.

They all WORK the same.

Here is the manual for my change over regulator and a photo of the indicator.

Also a Propane Safety file.

I figured they all work the same.........just curious as to how the Cavagna worked when the red button is supposed to pop out.......I guess to prevent you from turning it back.
