The online installation guide was very interactive. I put in my existing wires and it gave me an illustrated step by step guide to install the zen thermostat. Now I have this beautiful thermostat on my wall. The led display is just right for me to read up close and at a distance. The controls are super simple. And I like how it just snaps off the wall if I want to remove it and snaps on to put it back. No annoying clips or screws.
All in all I am happy that I chose this thermostat.
