Information About AS-UNT141-1
The AS-UNT141-1 is the screw-terminal version of the UNT111 controller, providing fixed screw terminals for field wiring and a spare 6-pin Zone Bus phone jack. It operates from a 24 VAC supply and includes an 80C652 processor, 32K RAM, 64K ROM, and 8K EEPROM. The controller is intended for applications such as unit ventilators, fan coils, heat pumps, air-handling units, and other terminal HVAC equipment.
Key Features:
- Unitary Controller: Provides programmable control for compatible HVAC equipment.
- Six Binary Outputs: Provides six 24 VAC triac outputs for connected equipment.
- Two Analog Outputs: Provides 0–10 VDC analog control outputs at up to 10 mA.
- N2 Communication: Supports communication with Johnson Controls Metasys systems.
- N2 Isolation: Provides isolated N2 bus communication.
- Screw Terminals: Uses fixed screw terminals for field I/O connections.
- Zone Bus Interface: Includes a spare 6-pin Zone Bus phone jack.
- Standalone Operation: Can operate independently or as part of a Metasys network.
The AS-UNT141-1 provides configurable I/O and network communication for compatible HVAC control applications.
