You can customize an HVAC schedule to heat or cool your home (or church) as needed (such as setting the AC higher in the daytime when everyone is at work or school & then cool down before the family comes home). And you can link them to the internet and reset the system to the temperature you want when you arrive home from a trip. I set our church thermostats to heat or cool beginning a couple of hours before people arrive & automatically raise or lower the temperature to save money when no one in there.
It’s awesome. I sit downstairs in an hour before I’m ready to go to bed. I’ll turn on the upstairs air to 71 and in an hour. It’s ready it’s beautiful.
It is very easy to use. The only thing that would be helpful is when using the wi-fi if it gave you the capability to put a hold time on the temperature, i.e. change to 70 and hold for two hours.
