Lot's of people have upgraded to the new SMART thermostats like the NEST, allowing us to monitor and control our furnace or heat pump remotely. This technology helps us save natural resources. FYI: If you sign up with HomeServe USA, a national warranty company that I work for, you may quality for a FREE NEST thermostat! I install them and will answer your questions.They retail for around $275 at Lowe's. It takes a few hours to get it installed and programmed. By the way, if you research these you will find that some units fail to keep the battery charged and the furnace will shut down!
