Quick Overview

Aprilaire 6504 Intelligent 4-Zone Comfort Control system.


The Aprilaire 6504 Intelligent 4-Zone Comfort Control system provides the ultimate in control and convenience. The system eliminates inconsistent, uncomfortable temperatures in your home by utilizing an Aprilaire Model 8570 Thermostat in up to four separate areas or “zones”. These thermostats are connected to a central control system which selectively open and close a dedicated series of dampers, delivering conditioned air only where you need it, when you need it, thus letting you customize your comfort while saving you money on energy costs.

Each Aprilaire 8570 thermostat is connected to the Aprilare Model 6504 Control Panel which is located near your heating and cooling system. The Model 6504 Panel shares information between thermostats and opens and closes dampers located in your system’s ductwork to control heating and cooling needs in each zone. But the Model 6504 Panel can go well beyond perfect temperatures to achieve the ultimate in home comfort and convenience. It can also control other Aprilaire Indoor Quality products to help you achieve total whole-home comfort 365 days a year.
