Honeywell PXCXF1207882

Product introduction

The Honeywell PXCXF1207882 is a high-performance building automation controller designed to optimize the operation of HVAC, lighting, and energy management systems in commercial and industrial facilities. As part of Honeywell’s Excel Web series, this controller combines powerful processing capabilities with flexible I/O configuration, making it a versatile solution for medium to large-scale building automation projects.

Honeywell PXCXF1207882 serves as a central hub for monitoring and controlling building systems, leveraging open protocols like BACnet to integrate with a wide range of devices and management platforms. Its robust hardware and expandable architecture allow it to adapt to evolving building needs, from simple zone control in offices to complex energy optimization in hospitals or data centers. Whether deployed as a standalone controller or part of a networked system, Honeywell PXCXF1207882 delivers precise control, data analytics, and energy efficiency—reducing operational costs while enhancing occupant comfort.

Core advantages and technical highlights

Powerful processing and memory: PXCXF1207882 features a 32-bit ARM Cortex-A9 processor running at 800 MHz, paired with 512 MB RAM and 4 GB flash storage. This combination enables it to handle complex control algorithms, store historical data, and run energy management applications without performance degradation. For example, it can simultaneously manage 12 HVAC zones, execute occupancy-based lighting schedules, and log energy consumption data for weekly reporting—all while maintaining responsive real-time control.

Flexible I/O configuration: With 12 universal inputs (configurable for temperature, humidity, pressure, or digital signals), 8 relay outputs (for fans, dampers, or lighting), and 4 analog outputs (for variable speed drives or valves), PXCXF1207882 adapts to diverse building systems. The universal inputs eliminate the need for signal converters, simplifying wiring and reducing installation time. This flexibility makes it suitable for retrofits, where existing sensors and actuators may use different signal types.

Open protocol compatibility: PXCXF1207882 supports BACnet/IP, BACnet MS/TP, Modbus, and Ethernet IP, ensuring seamless integration with third-party devices and building management systems (BMS). It can communicate with Honeywell’s Enterprise Building Integrator (EBI) or other BMS platforms, enabling centralized monitoring and control. This interoperability is critical for smart buildings, where data from HVAC, lighting, and security systems must work together to optimize efficiency.

Energy management capabilities: Equipped with built-in energy analytics tools, PXCXF1207882 monitors consumption patterns, identifies inefficiencies, and executes demand-response strategies. It can adjust HVAC setpoints during peak energy periods, schedule equipment operation to avoid high-tariff times, and generate reports on energy savings. In a typical office building, these features can reduce energy costs by 15-20% compared to conventional control systems.

Typical application scenarios

In large office complexes, PXCXF1207882 manages multi-zone HVAC systems, coordinating air handling units, variable air volume (VAV) boxes, and rooftop units. Its 12 inputs monitor zone temperatures, occupancy sensors, and outdoor air conditions, while outputs control dampers, fans, and heating/cooling coils. The controller uses proportional-integral-derivative (PID) algorithms to maintain precise temperature control (±0.5°C), adapting to occupancy changes detected by motion sensors to reduce energy use in unoccupied areas.

Hospitals utilize PXCXF1207882 to regulate critical environments like operating rooms, laboratories, and patient wards. The controller maintains strict humidity levels (40-60%) and pressure differentials (to prevent cross-contamination) by adjusting air exchange rates. Its analog outputs control variable speed drives for air handlers, ensuring stable airflow, while relay outputs manage backup systems during power outages. Integration with the hospital’s BMS allows remote monitoring by facility staff, ensuring compliance with healthcare regulations.

Data centers deploy PXCXF1207882 to control cooling systems, where precise temperature management (18-21°C) is essential for server reliability. The controller monitors inlet air temperatures at server racks (via its universal inputs) and adjusts chilled water valves or CRAC unit fans (via analog outputs) to prevent hot spots. It communicates with power distribution units (PDUs) via Modbus, linking cooling operation to server load for energy-efficient thermal management.

Installation, commissioning and maintenance instructions

Installation preparation: Mount PXCXF1207882 on a 35 mm DIN rail in a climate-controlled electrical closet, ensuring ambient temperature remains between 0°C and 50°C. Connect to a 24 VAC/DC power supply with 1 A overcurrent protection, using separate circuits for power and signal wiring to minimize noise. Run twisted-pair cable for analog signals and shielded cable for communication lines, grounding shields at the controller end. Label all I/O connections clearly (e.g., “Zone 3 Temp Sensor,” “VAV Damper Output”) for troubleshooting.

Commissioning and maintenance: Configure PXCXF1207882 using Honeywell’s EBI or EXCEL Web Commissioning Tool, defining input types, control logic, and communication settings. Calibrate analog inputs using a certified thermometer or pressure gauge to ensure measurement accuracy. Test control sequences (e.g., startup/shutdown of air handlers) and verify communication with the BMS. Perform quarterly checks to ensure firmware is up to date and clean dust from ventilation slots. Annually, inspect wiring connections for corrosion, verify relay operation, and recalibrate critical sensors to maintain control precision.
