Sorry to say we didn't buy this Thermostat. SMECO actually installed it for FREE....If you have SMECO they will install it for FREE It's a GREAT Thermostat because you can connect it to your WiFi. Using your phone you can change the Thermostat from anywhere especially if your traveling
I think it is awesome!!! My thermostats are inconveniently located in my house to adjust when I want. The remote feature is spot on. I have one programmed for changes and that is great too.
