Advanced VAV control solutions, engineered for precision and efficiency.
The ComfortID™ Single Duct Air Terminal Zone Controller is the ultimate solution for commercial HVAC systems, offering unmatched precision and flexibility. Designed to optimize climate management, this controller features Pressure Independent (VAV) control, Proportional Integral Derivative (PID) functionality and direct mounting on VAV box damper shafts. With support for auxiliary heating, demand-controlled ventilation and advanced communication protocols, this controller streamlines operations while improving occupant comfort. Its robust design ensures reliability and simplifies integration with Carrier Comfort Network (CCN) systems, leading to increased efficiency and cost savings.
Provides pressure‑independent VAV control for terminals up to 9000 CFM or 3.4 sq. ft. primary air inlet area.
Employs PID control to regulate airflow and maintain space temperature setpoints.
Supports zone humidity control (dehumidification) when a field‑installed humidity sensor is used.
Controls auxiliary heating types including:
Modulating (floating) hot water
Single‑position hot water
Single or two‑stage electric heat
Zone perimeter heat
Provides terminal fan control where applicable.
Includes automatic airflow transducer self‑calibration.
Designed for quick and easy commissioning and balancing.
Provides easy access to airflow sensor pneumatic connections.
Integrated supply air temperature sensor
Remote occupancy contact input for a field‑supplied occupancy sensor
Supports local setpoint adjustment with a field‑installed temperature sensor (with temperature offset)
