•'` Mebhanical Specifications - Variable Air Volume Single Duct Terminal Units
Item: Al, A2 City: 3 Tag(s): VAV -1-8, VAV -2-8, VAV -14
General Unit Information
The unit casing is comprised of 22 gauge galvanized steel. Outlet connection is slip and drive.
Agency Listing - The unit is UL and Canadian UL listed as a room air terminal unit. UL Control # 9N65. All Trane
terminal units are ARI 880 - 98 certified.
General Unit Clearance
Allow adequate clearance to meet NEC on control box side of unit to meet NEC. A minimum of one and one half duct
diameters of straight duct work, upstream of the air inlet connection, should be present for optimum airflow
measurement performance. Upstream duct work should be the same diameter as the primary inlet connection.
1/2" Matte - Faced Insulation
The interior surface of the unit casing, is acoustically and thermally lined with 1/2" 1.50 Ib.cu. ft. [24.00 kg. /cu. m.]
composite density glass fiber with 4.0 Ib. cu.ft. [64 kg. /cu. m.] high density facing. The insulation is UL listed and
meets NFPA -90A and UL 181 standards. The insulation R -value is 1.9. All cut edges of insulation are completely
encapsulated in metal to prevent erosion.
Air Valve Round
The air inlet connection is an 18 gauge galvanized steel cylinder sized to fit standard round duct. A multiple point,
averaging flow sensing ring is provided with balancing taps for measuring within +/- 5% of unit cataloged airflow. An
airflow versus pressure differential calibration chart is provided. The damper blade is constructed of a closed cell foam
seal mechanically locked between two 22 gauge galvanized steel disks. The damper blade assembly is connected to
a cast zinc shaft supported by self lubricating bearings. The shaft is cast with a damper position indicator. The valve
assembly includes a mechanical stop to prevent over stroking. At 4.0" w.g. air valve leakage does not exceed 1% of
cataloged airflow.
Air Valve Size - 08
Air Valve is 900 cfm [425 Vs] 8" inlet.
Air Valve Size -14
Air Valve is 3000 cfm [1416 Us] 14" inlet.
Electric Heat Coll
Factory provided and mounted, UL recognized, resistance open -type heater with airflow switch, a disc -type automatic
pilot duty thermal primary cutoff, and manual reset load carrying thermal secondary device. Heater element material
is nickel- chromium. The heater terminal box is provided with 7/8" knockouts for customer power supply. Terminal
connections are plated steel with ceramic insulators. Heater control access is left hand. Right hand control access is
optional.
Magnetic Contactor
An electric heater 24 volt contact for use with Direct Digital Control (D.D.C.) or Analog Electronic VAV Controls.
Power Disconnect Switch (for VCEF)
A factory provided interlocking door disconnect switch located on the electric heater control panel.
Line Fuse
A safety fuse located in the electric heater's line of power to prevent power surge damage to the electric heater for
VCEF. For VCCF and VCWF, the fuse is installed on the primary voltage hot leg in a control box.
Slip & Drive Connection
A slip and drive connection has two straight flanges on the top and bottom, and two drive connections on the left and
right sides. This is a standard option on all VAV single duct terminal units.
Electric Heat Transformer
A 40VA or 75VA transformer will be an integral component of the heater control panel dependent on unit load
requirements to provide 24 VAC for controls.
D.D.C. Actuator
Trane 3 wire, 26 GA, 3.4 VA, 1.7 W, 24 VAC, 50/60 Hz floating point control actuator with linkage release button.
Running torque is 35 in-lb (4 Nm) minimum and is non - spring return with a 90 second drive time. Travel is terminated
by end stops at fully opened and closed positions. An integral magnetic clutch eliminates motor stall. When Trane

, HealthNfet TI January 11, 2006
controls are not provided an integral 3 screW terminal is provided for field wiring. Operating temperature is 32 to 125
degrees Fahrenheit (0 to 50 degrees Celsius).
Direct Digital Controller
The microprocessor based terminal unit controller provides accurate, pressure independent control through the use of
a proportional integral control algorithm and direct digital control technology. The controller monitors zone
temperature set points, zone temperature and its rate of change, and valve airflow using a differential pressure signal.
Optionally, the controller can monitor either supply duct air temperature or CO2 concentration via appropriate sensors.
The controller is provided in an enclosure with 7/8" knockouts for remote control wiring. A Trane zone sensor is
required.
System Communications
The controller is designed to send and receive data from a Tracer Summit or other Trane Controllers, or a Varitrac
Central Control Panel. Current unit status conditions and set points may be monitored and/or edited via this data
communication feature. The network type is a twisted wire pair serial communication.
Override Commands
The following override commands may be received by the Unit Control Module (U.C.M.) from the Tracer System.
Control Mode, Action, Offset & Commands
* Control Mode - Occupied or Unoccupied
* Control Action - Heating or Cooling
* Control Offset - Enabling Control Offset will increase the cooling temperature setpoint and decrease the heating
temperature setpoint by a control offset value.
* Drive damper fully open.
* Drive damper fully closed.
* Drive damper to maximum airflow setpoint.
* Drive damper to minimum airflow setpoint.
* Disable unit heat.
* Reset - Enabling the reset function forces the controller and the flow sensor to recalibrate.
Editable Set points and Functions

Occupied and unoccupied heating temperature set point (30 °- 100°F) [-1.1°- 37.8°C]
Maximum flow set point (10- 100% of unit equivalent cataloged airflow)
Minimum heating and cooling flow set point (0, 10- 100% of unit equivalent cataloged airflow)
Cooling set point low and high limit Low (30 °- 100°F) [ -1.1 °- 37.8°C] High (30 °- 102°F) [ -1.1 °- 37.8°C]
Heating set point high and low limit (30 °- 100°F) [-1.1°- 37.8°C]
Hot water valve drive time
Air valve drive time
Fan Control Offset - determines at what point a parallel fan is energized. This can be a function of temperature
(degrees above heating set point) or primary airflow
Series Fan Configuration - allows series fan powered to shut off fan and close air valve when unit is unoccupied. Fan
will operate in unoccupied mode if reheat is active.
Local heating flow set point enable /disable and set point
Analog input mode - auxiliary temperature sensor or CO2 detector
Binary input mode - generic or occupancy detector

DDC Sequence of Operation
The unit controller continuously monitors the zone temperature against its set point and varies the primary airflow as
required to meet zone set points. Airflow is limited by minimum and maximum airflow set points.
DDC Controls Option DD04
Basic Operation: On /Off Staged Electric Heat (Normally Open Outputs) (DDC /UCM)
A voltage signal from the zone sensor indicates the zone temperature is used by the unit controller to determine an
error from the set point. This error, as well as primary flow differential pressure, is used to determine damper position
within minimum and maximum cooling airflow set points. As the zone temperature drops to the heating set point,
primary airflow is controlled to minimum heating flow set point. Staged electric heat is energized.
