GENERAL
The zone controller is a single duct, fan powered, Variable
Air Volume (VAV) terminal control with a factory-integrated
controller and actuator. The zone controller maintains precise
temperature control in the sp ace by operating the terminal f an
and regulating the flow of conditioned air into the space. Buildings with diverse loading conditions can be supported by controlling reheat or supplemental heat.
The VAV Fan Terminal Zone Controller (33ZCFANTRM)
provides dedicated control functions for series fan or parallel
fan powered terminals, single duct terminals with 3 stages of
heat, or as a primary controller for dual duct or zone pressure
control applications.
The Single Duct Air Terminal Zone Controller
(33ZCVAVTRM) provides dedicated control functions for single duct terminals with modulating heat or up to 2 stages of
heat.
When the VAV Fan Terminal Zone Controller is used in
conjunction with a secondary terminal and the 33ZCSECTRM
secondary terminal zone controller, either dual duct or zone
pressurization applications can be supported.
Carrier’s Linkage system is an integrated combination of
Carrier Comfort Network (CCN) controllers for use with Single Duct air terminals and VAV Fan Powered terminals. The
Single Duct air terminal and VAV Fan terminal zone controllers are part of the Carrier ComfortID system.
Devices manufactured by Carrier which have Product Integrated Controls on the same communication bus as the zone
controller, air handlers (such as the 39L,T), or large rooftop
units do not require an external controller to function as part of
a Carrier linkage system. These air handlers or large rooftop
units feature factory-installed Product Integrated Control (PIC)
controllers that are directly compatible wi th the system. Consult your local Carrier representative for the complete list of
compatible air handlers. The Comfort System AirManager
(CSAM) or the CC6400 supports linkage for non-Carrier devices or air handlers. Figure 1 shows an example of a Carrier
linkage system.
INSTALLATION
General —
direct digital control (DDC) controller for variable air volum e
(VAV) air terminals. It can be retrofitted on units manufactured
by Carrier or other manufacturers to provide pressureindependent VAV control.
Each zone controller has the ability to function as a linkage
coordinator for systems with up to 128 zones. As a linkage coordinator, a zone controller will retrieve and provide system information to the air handling equipment and other zone controllers. A zone controller can function as a stand alone device
by installing a primary supply air sensor.
The zone controller monitors differential pressure from an
airflow pickup (or a pair of pickups) mounted on the terminal
box. It compares the resulting signal to an airflow set point in
order to provide pressure-independent control of the air passing
through the terminal.
The zone controller is connected to a wall-mounted, fieldsupplied, space temperature sensor (SPT) in order to monitor
zone temperature changes and satisfy zone demand.
On stand-alone applications or applications with heat, the
zone controller must be connected to a field-supplied supply air
temperature (SAT) sensor to monitor the temperature of the air
delivered by the air terminal.
Carrier’s Network Service T ool can be connected to the system at the SPT sensor if CCN communication wiring is run to
The zone controller is a microprocessor-based
the SPT sensor. The Network Service Tool can be used to adjust set points, set operating parameters, and fully configure the
zone controller or any device on the system.
Zone Controller Hardware —
The zone controller
consists of the following hardware:
• terminal control module
• torque-limiting damper actuator
• airflow transducer (velocity sensor)
• plastic enclosure
• one no. 8 x
1
/2-in. sheet metal screw (to prevent zone
controller rotation)
NOTE: A filter is not provided for the airflow transducer.
For installations on systems with a high degree of impurities, an air filter can be purchased and installed on the transducer high pressure pickup.
Figure 2 shows the zone controller physical details.
Figures 3-5 show the 3 different types of zone controllers.
Field-Supplied Hardware —
Each zone controller requires the following field-supplied components to complete its
installation :
• air terminal unit
• space temperature sensor
• transformer — 24 vac, 40 va
• two no. 10 x
sensor to duct, if required)
• two no. 6-32 x
1
/2-in. sheet metal screws (to secure SAT
5
/8-in. screws (to mount SPT sensor base
to electrical box)
• contactors (if required for fan or electric heat)
• supply air temperature sensor (required for terminal with
ducted heat)
• indoor air quality sensor (if required)
• relative humidity sensor (if required)
• one SPST (for each stage of electric heat, not required
for Carrier fan terminals)
• valve and actuator for hot water heat (if required)
• delta pressure airflow pickup
NOTE: When selecting an airflow pickup, it is the
designer's responsibility to select a sensor that provides the
desired ou tput at the design airflow.
•wire
• polyethylene tubing (for pressure pickup)
• bushings ( re qu ire d wh en m o un tin g SAT sensor in a duct
6-in. or less in diameter)
• primary air temperature sensor (if required)
SPACE TEMPERATURE SE NSOR — Each zone control-
ler requires a field-supplied Carrier space temperature sensor.
There are two sensors available for this application:
• 33ZCT55SPT, Space Temperature Sensor with Override
Button
• 33ZCT56SPT, Space Temperature Sensor with Override
Button and Set Point Adjustment
PRIMARY AIR TEMPERATURE SENSOR — A fieldsupplied, primary air temperature (PAT) sensor (part number
33ZCSENPAT) is used on a zone controller which is functioning as a Linkage Coordinator for a non CCN/Linkage compatible air source.
SUPPLY AIR TEMPERATURE (SAT) SENSOR — On
stand-alone applications or applications with ducted heat, the
zone controller must be connected to a field-supplied supply air
temperature (SAT) sensor (part number 33ZCSENSAT) to
monitor the temperature of the air delivered by the air terminal.
The zone controller will maintain the air temperature below the
maximum air temperature in ducted heating applications.

RELATIVE HUMIDITY SENSOR — The
33AMSENRHS000 relative humidity sensor is required for
zone humidity control (dehumidification).
NOTE: The relative humidity sensor and CO
sensor cannot
2
be used on the same zone controller.
INDOOR AIR QUALITY (CO
) SENSOR — An indoor air
2
quality sensor is required for optional demand control ventilation. The CGCDXSEN002A00 CO2 Sensor is an indoor,
wall mounted sensor with an LED display. The
CGCDXSEN003A00 CO
Sensor is an indoor, wall mounted
2
sensor without display .
NOTE: The relative humidity sensor and CO
sensor cannot
2
be used on the same zone controller.
Mount Zone Controller
LOCA TIO N — The zone controller must be mounted on the
air terminal’s damper actuator shaft. For service access, there
should be at least 12 in. of clearance between the front of the
zone controller and adjacent surfaces. Refer to Fig. 6.
MOUNTING — Perform the following steps to mount the
zone controller:
1. Visually inspect the damper and determine the direction in which the damper shaft moves to open the
damper — clockwise (CW) or counterclockwise
(CCW). Refer to Fig. 7.
If the damper rotates CCW to open, it does not require
any configuration changes.
If the damper rotates CW to open, then the damper
actuator logic must be reversed. This is done in the
software when performing system start-up and damper
calibration test. Do not attempt to change damper rotation by changing wiring. This will upset the damper
position feedback potentiometer readings.
2. Rotate the damper shaft to the fully closed position.
Note direction of rotation.

3. Press the release button on the actuator and rotate the
clamp in the same direction that was required to close
the damper in Step 2.
4. Press the release button on the actuator and rotate the
actuator back one position grad uat i on. Releas e t he b utton and lock the actuator in this position.
5. Mount the zone controller to the terminal by sliding
the damper shaft through the actuator clamp assembly.
Secure the zone controller to the duct by installing
the screw provided through the gromm et in the antirotation tab. Be sure the floating grommet is in the
center of the slot. Failure to center the grommet may
cause the actuator to stick or bind.
6. Tighten the actuator clamp assembly to the damper
shaft. Secure by tightening the two 10-mm nuts.
7. If the damper has less than 90 degrees of travel
between the fully open and fully closed positions, then
a mechanical stop must be set on the actuator. The
mechanical stop prevents the damper from opening
past the maximum damper position. To set the
mechanical stop, perform the following procedure:
a. Press the actuator release button and rotate the
damper to the fully open position.
b. Using a Phillips screwdriver, loosen the appropri-
ate stop clamp screw.
c. Move the stop clamp screw so that it contacts the
edge of the cam on the actuator. Secure the stop
clamp screw in this position by tightening the
screw.
8. Verify that the damper opens and closes. Press the
actuator release button and rotate the damper. Verify
that the damper does not rotate past the fully open
position. Release the button and lock the damper in the
fully open position.

Connect the Power Transformer —
An individual,
field-supplied, 24 vac power transformer is recommended for
each zone controller. If multiple zone controllers are powered
from one power transformer (100 va maximum for UL [Underwriters’ Laboratories] Class 2 conformance), maintain polarity
on the power input terminals. All transformer secondaries are
required to be grounded. Use only stranded copper conductors
for all wiring to the zone controller. Wiring connections must
be made in accordance with NEC (Nati onal Electrical Code)
and local codes. Ground the transformer at the transformer location. Provide an 18-gage, green, chassis ground wire at the
terminal.
The power supply is 24 vac ± 10% at 40 va (50/60 Hz).
For 33ZCVAVTRM zone controllers, the power requirement sizing allows for accessory water valves and for electric
heat contactor(s). Water valves are limited to 15 va on both
two-position and modulating hot water. The electric heat contactor(s) are limited to 10 va (holding) each.
For 33ZCFANTRM zone controllers, the power requirement sizing allows for accessory water valves and for the fan
contactor. Water valves are limited to 8 va on both two-position
and modulating hot water. The fan contactor is limited to
11 va (holding).
NOTE: If a water valve or electric heat contactor exceeds
these limits, or external contactors are required for electric
heat, then it is recommended a 60 va transformer be used.
The maximum rating for any output is 20 va.
NOTE: Do not run sensor or communication wiring in the
same conduit with line-voltage wiring.
NOTE: An accessory conduit box (part no. 33ZCCONBOX) is
available for conduit wiring connections to the zone controller.
Perform the following steps to connect the power
transformer:
1. Install the field-supplied transformer in an electrical
enclosure that conforms to NEC and local codes.
2. Connect 24 vac from the transformer as shown in the
applicable wiring diagram (Fig. 8A-J).
Connect Airflow Pickups —
The zone controller determines velocity pressure by obtaining the difference between
high and low duct pressure from two airflow pickups. The
pickups are connected to barb fittings on the zone controller
1
with
/4-in. polyethylene tubing. All piping for this purpose
must conform to local codes.
Figure 9 indicates the positions of the two barb fittings.
Perform the following steps to install and connect the air-
flow pickups:
1. Select a location on the air handler’s supply air duct
where the airflow pickups will be installed. The location should be one where there are at least three duct
diameters of straight duct upstream of the pickups. If
this requirement is not met, stable airflow measurements may not be possible.
2. Mount the field-supplied airflow pickup(s) in the duct,
following the manufacturer' s directions. Two individual pickups may be used, one for high pressure airflow
and one for low pressure airflow . A dual pickup, which
combines the two functions, may also be used. When
using individual pickups, make sure that the one for
high pressure airflow faces upstream, in the direction
the air is coming from, and the one for low pressure
airflow faces downstream, in the direction the air is
going to.
3. Use field-supplied
1
/4-in. tubing (rated for the application) to connect the high pressure airflow pickup to
barb fitting P1 on the pressure transd ucer. At the zone
controller, the P1 fitting is on the side with the filter
installed. Be careful to avoid sharp bends in the tubing,
because malfunctions may occur if the tubing is bent
too sharply. Use at least 2 ft of tubing for reading
stability.
1
4. Use field-supplied
/4-in. tubing (rated for the application) to connect the low pressure airflow pickup to
barb fitting P2 on the pressure transducer. Be careful to
avoid sharp bends in the tubing, because malfunctions
may occur if the tubing is bent too sharply. Use at least
2 feet of tubing for stability.
