VVT® Bypass Controller with Integrated Actuator 33ZCBC-01 Product Integrated Controller

Product Integrated Controller

The Bypass Controller is a component of Carrier's 3V system and is used to regulate the supply duct static pressure for variable volume and temperature applications. The Bypass Controller is an essential system component that allows constant volume HVAC equipment to provide zone level temperature control. The Bypass Controller provides the following features:

• System or stand-alone operation
• Integrated pressure sensor
• Determines system-operating mode
• Air source leaving air temperature lockouts

The Bypass Controller operates on the 3V system network and is compatible with all Carrier communicating devices. A user interface is not required for everyday operation of the bypass controller. The Bypass Controller can be configured or operated through the Carrier Network with optional interface tools including the System Pilot or Carrier Software.

Feature
 

• Primary air temperature and pressure sensors determine system operating mode to ensure proper operation in case of communication failure.
• Air Source leaving air temperature protection minimizes the occurrence of heating and/or cooling lockouts based on unacceptable discharge temperatures.
• Quick and easy commissioning and balancing process via a dedicated maintenance table
• Stand-alone or linked system operation
• Carrier linkage system capability
• Foreign language support for ASCII based character sets
• Carrier communicating network device
• High-speed (38.4K baud) communications network
• Thermistor type duct temperature sensor
• Pressure sensor
• UL94-5V plenum rated controller housing
• Actuator preassembled to housing and rated at 35 in.-lb (3.95 N-m) torque, an adjustable 90-degree stroke, and provides 90-second nominal timing at 60 Hz
• Actuator assembly has an integrated conduit box and cover
• Both covers for the control are hinged
• Actuator suitable for mounting onto a 3/8-in. (9.5 mm) square or round VVT box damper shaft or onto a 1/2-in. (13 mm) round damper shaft. The minimum VVT box damper shaft length is 13/4-in. (45 mm)
• Actuator will operate with dampers having 90, 60, and 45 degree strokes
• Mounts directly onto pressure dependent box damper shaft
• Can drive up to 4 linked damper actuators
• Designed for vertical or horizontal mounting
