Variable Volume/Variable Temperature (VVT®)

Multiple Zone HVAC Control System

Model Number:

33ZCVVTZC-01 Zone Controller

33ZCBC-01 Bypass Controller

33PILOT-01 System Pilot

Part 1 — General

1.01 SYSTEM DESCRIPTION

The 3V™ control system shall consist of program-

mable, multiple communicating Zone Controllers;

and a Bypass Controller. The system shall also

include a complete array of input and output

devices. The system shall provide full control of

HVAC heating and cooling equipment in a multiple

zone application. The 3V system shall be capable of

operating as a stand-alone system or networked with

multiple systems connected on a communications

bus to communicating air source controllers.

1.02 DELIVERY, STORAGE AND HANDLING

The products shall be stored and handled per manu-

facturer’s recommendations.

Part 2 — Products

2.01 EQUIPMENT

A. General:

The control system shall be available as a complete

package with the required input sensors and devices

readily available. The system shall be capable of pro-

viding complete control of HVAC functions; variable

air zone control, bypass air control in both pressure

dependent and pressure independent applications.

Airside controls shall be capable of operating 3V sys-

tem dampers as well as VAV (variable air volume) ter-

minal boxes and Fan Powered terminal boxes with

and without supplemental heat sources at the zone.

All temperature sensors shall be capable of being read

and displayed in 0.1° F increments. Controllers shall

support either a local dedicated or remote System

Pilot capable of displaying sensor and input informa-

tion applicable to the controller in degrees Fahrenheit

or Celsius. The System Pilot shall be capable of dis-

playing the following information as a minimum:

System Pilot Linkage Coordinator Zone Con-

troller Display:

1. Space Temperature

2. Primary Air Temperature

3. Damper Position Desired

4. Damper Position Actual

5. Cfm (Pressure Independent Controllers Only)

6. Average Temperature from multiple remote

Room Sensor(s)

7. Zone Indoor Relative Humidity

8. Zone Indoor CO

concentration

9. Zone Supply Air Temperature

10. Outside Air Temperature

11. Air Source Mode

System Pilot Zone Controller Display:

1. Space Temperature

2. Damper Position Desired

3. Damper Position Actual

4. Cfm (Pressure Independent Controllers Only)

5. Average Temperature from multiple remote

Room Sensor(s)

6. Zone Indoor Relative Humidity

7. Zone Indoor CO

concentration

8. Zone Supply Air Temperature

9. Outside Air Temperature

10. Air Source Mode

System Pilot Bypass Controller Display:

1. System Pressure in hundredths of an inch

2. System Pressure Set Point

3. Damper Position Desired

4. Damper Position Actual

5. Air Source Supply Air Temperature

6. Air Source Mode

7. All applicable sensors shall be accessed for cali-

bration at the controller display.

B. Rooftop Controller Interface:

The VVT zone controller shall be capable of zone

demand data coordination with a communicating

rooftop. Set point and temperature information

from the zones shall be shared with the rooftop con-

troller so that the rooftop controllers error reduction

calculations can determine the proper number of

heating or cooling stages to operate in order to bal-

ance the system load.

C. Memory and Timeclock:

The system shall not require the use of batteries for

any data storage. The VVT zone controller and

Bypass Controller shall have a Non-Volatile Memory

providing indefinite storage of configuration data.

The VVT zone controller shall have a 365-day soft-

ware clock with built in daylight savings time and

leap year adjustment. In the event of power failure,

the timeclock may be automatically updated with

current time and date from a network Time Sync

device. The network time sync device shall update

all software and Hardware clocks on the communi-

cations network twice a day. The System Pilot shall

be capable of sharing time information with other

3V system controls or any other General Purpose

Electronic Controller existing on the communica-

tions bus with timeclock capabilities. The VVT zone

controller shall also have the capability of changing

occupancy mode by reading a set of discrete, dry

contacts controlled by an external timeclock.

D. Set Points:

1. The VVT zone controller shall utilize and store

the following set points:

a. Occupied Heating Set Point
