Rode last season with the poc 2.0 it's made with a ballistic dough which is pliable but hardens on impact. Held up well, it's little spendy but it saved my azz a few times. It has also become my mid layer.
For the perticular stat you have, you need the common wire for the stat to function I've been installing these since they came out. If you can't get a common wire ran there is another honeywell stat that only requires 2 wires but it is way more expensive and the wifi gateway is a seperate component.
The wire you want is called LVT. Chances are the existing 2 wire is stapled to the stud and you will not be able to pull with it. The LVT you want is 18 gauge/ 6 conductor. Hook up the g terminal as well and you'll be able to control the fan from the stat. And c,r,and w.
You have to bring a common wire up to the stat to "power" the stat. Will not work without. While ur at it you might as well pull up more control wires so you can control your fan from the stat as well. Do u plan on installing a/c? If u do you'll need some for that as well. Put in 18/6 you...
