One thing I love about my smart thermostat is the fact that it runs on regular double A batteries.
This makes it so easy to change them out and is very inexpensive as well.
When the batteries are getting low the smart thermostat will flash a warning across the digital reader that will tell you that the battery is low. When this happens, you have about a month to replace them. I love the fact that the warning gives you that long before the batteries go dead. This way I do not have to rush out to the store to buy batteries after a long day of work. I can wait till the following weekend without having to worry that the smart thermostat is going to fully stop working. Because if the smart thermostat batteries go dead, your central heating and air conditioning system also goes dead. And if it is a very hot or very cold time of the year, that is the last thing you want to happen! I spend money on getting my central heating and air conditioning system tuned up and checked up every single season. Which I do that to prevent heating and air conditioning system break downs. I would hate to have my central heating and air conditioning system unit fully stop working all because I forgot to change the battery in my smart thermostat. This kind of thing just isn’t the right thing to ever have happen. So I am glad for the warning that it gives!
