I use those but they don't have a night drop ( mine didn't) ..
Matter of fact here the entire part number a419abc-1c. I got one on my desk ( second one I need to wire it up) . I found that these work great, aslo can save on shipping talk ot a perosn ( possible a buddy) that works in heating/ac or even possible a electrian they can possible order one. they easy to wire up. I paid 60 for the first one , and 68 bucks for the second one I got the neighbor to order it it saved me a 45 mintue ride. If you get one and need help pm me . I think I am going to do a diy when I wire up my second one. to help people.
