You like to be control, and our Prestige® IAQ Comfort System is happy to oblige. With this one thermostat, you can control up to three whole-house systems, including humidifier, dehumidifier, air-conditioner and ventilation. But we didn’t stop there. There’s also a high-definition, full-color display that’s easier to read. And optional add-ons such as the Portable Comfort Control that allows you to adjust temperature from anywhere in the home. For convenience, control and comfort, this thermostat delivers.
