This furnace sensor may change temperatures in dozens of homes in just seconds! With technology, our lives continue to become more comfortable and easier – except when they don’t!

A furnace thermostat has to be can constantly learn your schedule. It’s doing so helps it make sure that in the late afternoon, for example, the furnace doesn’t come on and blow cold air into the house.
