WIRING CONNECTIONS — Field wiring is 18 to 22 AWG

(American Wire Gage). The VVT zone controller is a NEC

(National Electronic Code) Class 2 rated device.

POWER SUPPLY — The 33ZCVVTZC-01 zone controller

requires a 24 vac ± 10% at 40 va (60 Hz) power source.

COMMUNICATIONS — The number of controllers is limit-

ed to 128 devices maximum, with a limit of 8 systems

(Linkage Coordinator configured for at least 2 zones). Bus

length may not exceed 4000 ft (1219 m), with no more than

60 devices on any 1000 ft (305 m) section. Optically isolated

RS-485 repeaters are required every 1000 ft (305 m).

At 19,200 and 38,400 baud, the number of controllers is

limited to 128 maximum, with no limit on the number of Link-

age Coordinators. Bus length may not exceed 1000 ft (305 m).

Bypass Controller (33ZCBC-01) — The VVT By-

pass 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 control assembly contains an integral

actuator assembly that is field mounted to the VVT terminal

damper shaft, similar to the mounting of a standard actuator.

The actuator is rated at 35 lb.-in. (3.95 N-m) torque, a

90-degree stroke, and provides a 90-second nominal time at

60 Hz. The actuator is suitable for mounting onto a

-in.

(9.5 mm) square or round damper shaft, or onto a

-in.

(13 mm) round damper shaft. The minimum damper shaft

length is 1

-in. (45 mm). The bypass controller is designed for

vertical or horizontal mounting.

The bypass controller is provided with removable connectors

for power and communications. The bypass controller has non-

removable screw type connectors for inputs. The removable

connectors are designed so that they can be inserted one way so

as to prevent installation errors. The bypass controller also

provides an RJ-11 modular phone jack for the Network

Service tool connection to the module via the Carrier network

communications.

Field-installed actuators may also be used. Belimo Multi-

Function technology actuators may be ordered direct from

Belimo. The following accessory actuators may be used

instead of the integrated actuator:

• NM24-MFT US P-30002 — 70 in.-lb actuators with

floating point control and 0 to 10 vdc feedback.

• AM24-MFT US P-30002 — 160 in.-lb actuators with

floating point control and 0 to 10 vdc feedback.

The following actuators may be used as linked actuators.

Up to four actuators may be linked to the master actuator:

• LM24-MFT US P-10002 — 35 in.-lb actuators with

0 to 10 vdc control and 0 to 10 vdc feedback.

• NM24-MFT US P-10002 — 70 in.-lb actuators with

0 to 10 vdc control and 0 to 10 vdc feedback.

• AM24-MFT US P-10002 — 160 in.-lb actuators with 0

to 10 vdc control and 0 to 10 vdc feedback.

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 by-

pass controller. The Bypass Controller can be configured or op-

erated through the Carrier Network with optional interface

tools including the System Pilot or Carrier software.

The bypass controller provides the following features and

benefits:

• 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

• High-speed (38.4K baud) communications network

• Thermistor type duct temperature sensor

• 0 to 2 in. wg pressure sensor

• UL94-5V plenum rated controller housing

FUNCTIONS — Functions of the bypass controller are:

• Auto pressure sensor zero calibration

• Manual pressure sensor calibration

• High end pressure transducer calibration

• Bypass damper calibration

• Bypass damper modulation

• Leaving air temperature protection

• Network tables and alarms

• System Pilot interface

INPUTS

• Duct temperature sensor

• Damper position feedback potentiometer (factory installed)

• System pressure (factory installed)

OUTPUTS

• Integrated factory-wired pressure dependent damper
