Can you connect this thermostat to a smart phone and control it that way?

I'm confused.....it says the unit has WiFi connectivity.

is this a 2 wire or 3 wire

Depending on how old the wiring in your house is,our house was built in 1982.I had 2 wires,a red and a white,on the thermostat,these are labelled R and W.It is easy to install and works great.
