AIRLINK® ZONED AIR SYSTEM Airlink is a zone temperature control system for commercial office buildings. Manufactured and sold since 1989, it makes it possible for each individual office to have its own thermostat even though the building may have only one air conditioner. The system includes zone thermostats, motorized air dampers, and network communications. The Airlink product line is in its third generation and competes directly with products from Trane and Carrier. Airlink is sold through independent distributors and by Armstrong Air Conditioning, a subsidiary of Lennox Air Conditioning. The graphic is from the Power-Point Presentation used by Airlink dealers.
