I believe the controller is a Pro C, I would have to go look to be sure.
After looking at a lot of models, that is one of the few with the built in transformer, makes it much better for outdoor installation. And the price is right.
The lock has been broken off, so I think some of the problems are program tampering and I know it's been left open and rained in many times.
That's probably what I will go back with. Get it programed and lock it, hopefully it will stay that way!
You recommend a wireless rain/freeze sensor. Is there an advantage to the wireless over wired? This is on an outside wall, easy to wire.
