Information About AS-UNT1108-0
The AS-UNT1108-0 is part of the Johnson Controls UNT1100 Series of digital unitary controllers developed for distributed HVAC control and energy management. Designed to operate as a standalone programmable controller or as part of a Metasys N2 building automation network, it provides flexible control for rooftop units, air handling units, heat pumps, unit ventilators, and fan coil systems. The controller supports multiple analog sensor types, configurable digital inputs, and high-capacity relay outputs, allowing it to manage compressors, fans, dampers, valves, and auxiliary equipment. Its rugged industrial construction, wide operating temperature range, and flexible mounting options make it suitable for commercial, institutional, and industrial HVAC installations.
Key Features:
- Six universal analog inputs: Compatible with 1 kΩ RTD, 0–10 VDC, and 0–2 VDC input signals.
- Six binary inputs: Supports 24 VAC dry-contact devices and status monitoring.
- Eight relay outputs: Class 2 relay outputs rated at 2 A at 24 VAC for equipment control.
- Metasys N2 communication: Integrates directly into Johnson Controls building automation systems.
- Programmable control logic: Supports customized HVAC sequences and operating strategies.
- Designed for single-zone HVAC: Ideal for rooftop units, heat pumps, air handlers, and unit ventilators.
- Low power consumption: Requires only 7 VA excluding connected loads.
- Wide operating temperature: Operates reliably from -40°C to 60°C.
- Flexible installation: Supports both DIN rail and surface mounting.
- Industrial-grade construction: Built for long-term continuous operation.
- Diagnostic capability: Simplifies commissioning and troubleshooting.
- Multiple wiring options: Compatible with various field devices and sensor configurations.
The AS-UNT1108-0 delivers the reliability and precision required for commercial HVAC control, building automation, and energy management applications.
