One thing I love about my smart control unit is the fact that it runs on two simple double A batteries. This makes it so easy to change them out and is truly cheap as well. When the batteries are getting low, the smart control unit 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 like 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 control unit is going to fully stop entirely working. Because if the smart control unit batteries go dead, your central heating and A/C system also goes dead. And if it is a truly tepid or cold time of the year, that is the last thing you want to happen! I spent money on getting my central heating and A/C unit tuned up and they also ran tests every single season. I do that to prevent heating and A/C unit breakdowns. I would hate to have my central heating and A/C unit fully stop working, all because I forgot to change the battery in my smart control unit. This kind of thing just isn’t the right thing to ever happen, so I am blissful for the warning that it gives!
