Johnson Controls has added a zoning product to its York® Affinity™ Communicating Control product offering that is capable of achieving both temperature and humidity setpoints.

The touch screen zoning Communicating Control can be used as a master and zoning sensor, providing up to six zones of control with a single zone panel. The York product offers a choice of three communicating sensors: a touch screen sensor with the ability to control temperature and humidity levels in all zones; a zone display that allows for temperature and fan adjustability; and a zone sensor.

Fan airflow adjustments can be made by zone to compensate for ductwork variability, and the control enables fan programming by zone. The zoning control also features damper flexibility, including power open/power close dampers (required when not using an optional bypass damper), normally open dampers and normally closed dampers.

Like the non-zoning product, the zoning Communicating Control communicates with all key components in a home comfort system, providing total system integration that ensures maximum system efficiency and homeowner comfort while equipping contractors with a reliable, distinctive tool to increase profits and build their business. In addition to displaying equipment and accessory status, the control offers a simplified four-wire plug-and-play design that eliminates time-consuming wiring and system checking at installation. An autoconfiguration feature automatically recognizes and configures new compatible components.  

The touch screen display can be configured to give homeowners the level of information they desire, including basic or detailed fault alerts with the contractor’s contact information prominently displayed. The tool also provides maintenance reminders that encourage homeowners to continue working with the contractor to maintain their home comfort system and ensure its efficiency.
