How Communicating Zoning Provides Comfort and Efficiency

All the components of a communicating zoning system talk to each other to actively monitor your individual room or zone conditions and adjust operation automatically without you having to do anything further.

Combining our award-winning YORK® Affinity™ variable-capacity, premium-efficiency units with our Hx™3 communicating thermostats and sensors enables you to control individual space conditions. The combination also minimizes temperature swings that can occur with conventional systems, and the energy required to overcome them, for optimized comfort.

Complete Control – Anytime, Anywhere

The innovative, easy-to-use Hx? app empowers you to take full control of your HVAC system from your smart device. Intuitive icons and a simplified set-up process make the app easy to use, while granting remote dealer access ensures that any issues can be easily shared with your HVAC professional to speed service. Our recently re-engineered app has new and expanded features like automatic pairing with your thermostat, simplified secure login, new home and away modes, and geo-fencing capabilities.

Choose Your Level of Control

Zone sensors and thermostats monitor your space conditions, and like the app, they allow you to change your settings for specific comfort needs. The Hx?3 Communicating Zoning System allows you to choose any combination of secondary zone sensors and thermostats to meet your needs. Take advantage of higher-level functions like zone humidity monitoring and control with advanced communicating thermostats.
