Simplifying HVAC control for efficient building climate solutions.
The VVT® Bypass Controller with Integrated Actuator (33ZCBC-01) is an essential component for Carrier’s Comfort Network 3V System, designed to regulate supply duct static pressure in variable volume and temperature applications. By providing precise temperature control at the zone level in constant volume HVAC systems, this controller enhances energy-efficient systems while ensuring uninterrupted comfort. Integrated pressure sensors, leaving air temperature protection and quick commissioning, offer users a practical and reliable HVAC control technology. Compatible with Carrier communicating devices, the Bypass Controller furthers building climate solutions with seamless integration and robust performance.
Primary air temperature and pressure sensors determine system operating mode to ensure proper operation during communication failures.
Air source leaving‑air temperature protection reduces the risk of heating or cooling lockouts caused by unacceptable discharge temperatures.
Control logic complies with ASHRAE 62.1 ventilation requirements.
Supports stand‑alone or linked VVT system operation.
Includes Carrier airside linkage capability for coordinated system control.
Supports foreign‑language ASCII character sets.
Integrated thermistor‑type duct temperature sensor
Integrated pressure sensor
