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.
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
UL94-5V plenum rated controller housing
