AS-UNT1144-0

The AS-UNT1144-0 controller by Johnson Control is a Metasys UNT1100 series UNT or Unitary Controller. This controller controls various HVAC system components by orchestrating their interactions for seamless system operation. It has 6 analog inputs that are specifically designed to operate as 1K-OHM RTD inputs at voltage ratings of 0-2V DC or 0-10V DC. Additionally, the AS-UNT1144-0 controller has 6 binary inputs that can be used as 24V AC dry contact inputs, and these inputs support external signals and event triggers, enhancing the controller's adaptability to environmental changes. The AS-UNT1144-0 controller also has 4 analog outputs rated at 0-10V DC at 10 mA, and 4 binary outputs featuring a (Class 2) 2-Amp relay at 24V AC. These outputs enable the controller to execute switching operations seamlessly for devices like fans, valves, and pumps. The AS-UNT1144-0 controller often operates as a coordinator device. It interprets inputs from various sources, including analog sensors or binary triggers, processes these inputs, and generates suitable outputs, often in the form of voltage or relay-based signals. This allows the AS-UNT1144-0 controller to maintain desired operating conditions, enforce predefined responses, and facilitate seamless communication among different system components. The AS-UNT1144-0 controller can operate with 20-30V AC of supply voltage at 50 or 60 Hertz with a Class 2 type of transformer. Its maximum power consumption rating is 7 VA. The AS-UNT1144-0 controller can be mounted on a DIN rail or mounted on a surface with mounting screws. Its ambient operating temperature range is -40 to 140 degrees Fahrenheit. The AS-UNT1144-0 controller supports N2 and Zone Bus interfaces.
