When having a smart temperature control like I do, you need to get to feel how to work it, what it does what and how it operates! One thing I have learned about the smart temperature control that is actually convenient is the fact that there is a yellow light that comes on when it is time for the batteries to be substituted; however, a lot of other smart temperature controls I have seen do not have this, then they just display words that say low battery.
This is easily overlooked if you are not checking for it every single day of your life! But with the smart temperature control I have, this yellow light is easily great because you can not help but notice the light when you happen to walk by the smart temperature control because it is yellow and actually bright. This way, you can change the batteries in the smart temperature control long before they go dead and leave you without a HVAC that is fully finally working; when the batteries in the smart temperature control go dead your central HVAC will fully stop finally working, however it will be like you had a heat and cooling device breakdown! But when this happens you do not need to call the local HVAC company for them to send out a certified heat and cooling system specialist to maintain your central heating and cooling system! You just simply change the batteries in your smart temperature control and it will be up and running again right away. This is also why I am so grateful for the yellow light on my smart temperature control!
