A:AnswerThe easiest way is to go online and use the assistant. (It’s in the instructions) It will allow you to input your wires and tell you exactly where to place them as well as whether or not the thermostat is compatible with your system. If it is. It will tell which wires you can omit (if any) it makes things pretty fool proof. Hope this helps
A:AnswerThis should work since you have the ability to use your app to keep the system off. You would just turn the system on with your app to a designated temp & it will show you how many hours it would take to heat to that temp.
