• Provides true independent temperature control by zone
• Built-in test buttons automatically confirm operation
• Alter four separate zones' thermostats to heat or cool as desired

Designed to work with the Aprilaire® Programmable Thermostat (#3020A), the Aprilaire® 4-Zone Comfort Control System goes well beyond controlling heating and cooling and into the role of orchestrating the entire HVAC system to increase your comfort and convenience while saving you energy and money. The 4-Zone Comfort Control System works as the nerve center that provides a central wiring hub and information interchange for the system along with the Programmable Thermostat to work with single or multi-stage forced air heating/cooling equipment and control two, three, or four zones. To operate the system, just set each zone's thermostat to your desired comfort. Information is then shared among thermostats through the 4-Zone Comfort Control System to optimize performance and convenience. This means you can turn on/off, adjust or simply view any thermostat from any other thermostat. Service reminders help keep all the systems working at peak performance.
