The Aprilaire® 8300 Series thermostats were designed to be easier for technicians to install and program and simple for homeowners to use. They are available for both heat/cool (including multistage) and heat pump applications. Programmable and nonprogrammable versions are offered for each application. Features include a large, backlit display that reads “DONE” at the end of programming and built-in alerts that indicate when air cleaner filters and humidifier water panels need changing.
