I found this accessory on The Carefree of Colorado web site. My electric awning is a Carefree brand and is a Travel'r Type.
If you go to there website, Look under-- Travel Trailer-- Patio Awnings--Travel'r--Click Features tab, you will see-- NEW! Direct Response Electronics this is were you can find more info about it.
I did not install it myself, my dealer did, but I do believe I could have. They charged me $200 for Labor, $98.00 for the parts. I have played with and it works as described. I can now shake my awning and it will automatically roll up.
They also changed out my awning power switch inside my RV. It now has Two Switches that control my awning. One switch lets my awning out or back in, the other switch (which is new) is a power on or off switch. I like this because now I shouldn't have to worry about my awning accidently letting itself out while traveling.
My service manger told me he personally knows this has happened, they had tochange out a awning because of this. He also told me when they install a electric awning he always installs a ON, Off switch as a say guard.
You wanted more detail here you go.
