Carrier 33ZCFANTRM Fan Controller

The Carrier 33ZCFANTRM Fan Controller is a high-performance VAV Fan Terminal Zone Controller engineered for precise airside management in commercial HVAC environments. As a core component of the Carrier ComfortID System, this unit integrates a factory-installed actuator with a digital controller to provide pressure-independent VAV control using advanced PID algorithms. Built for versatility, it supports series or parallel fan-powered terminals, single duct terminals with up to three stages of heat, and dual duct applications when paired with a secondary controller. This 33ZCFANTRM zone controller mounts directly to the terminal damper shaft, supporting systems up to 9000 CFM with a robust 35 lb-in torque rating. It features plug-and-play compatibility with the Carrier Comfort Network (CCN), allowing for seamless communication at speeds up to 38.4 kilobaud. Technicians benefit from zero-calibration airflow transducers and automated commissioning sequences, ensuring accurate airflow regulation and demand-controlled ventilation. Whether managing modulating hot water or multi-stage electric reheat, this controller maintains tight setpoint tolerances for optimized zone comfort and energy efficiency.

• Streamlined Installation: Features an integrated VAV actuator that mounts directly to 3/8-inch or 1/2-inch damper shafts, eliminating the need for separate linkages.
• Advanced Integration: Fully compatible with Carrier Comfort Network (CCN) for centralized building management and real-time remote diagnostics.
• Flexible Heating Support: Controls various heat types, including 3-stage electric heat, two-position hot water, and modulating hydronic systems.
• Environmental Precision: Supports auxiliary IAQ sensors and humidity monitoring for comprehensive indoor air quality control.
• Reliable Performance: Utilizes pressure-independent control to maintain stable airflow regardless of duct static pressure fluctuations.

Is the 33ZCFANTRM compatible with non-Carrier building systems?
While optimized for the Carrier Comfort Network (CCN), it can operate as a standalone device when configured with a primary supply air sensor or integrated into larger systems via CCN-compatible gateways.

What is the maximum torque for the integrated actuator?
The integrated actuator provides 35 lb-in (3.95 Nm) of torque, suitable for most standard VAV terminal box dampers.

Does this controller support dehumidification?
Yes, the 33ZCFANTRM can manage zone humidity control when paired with a field-installed humidity sensor, allowing for active dehumidification sequences.
