This section describes the catalog
selection of single and dual-duct VAV
terminal units with specific examples.
A computer selection program is also
available to aid in selection of VAV
terminal units, but is not described
here.
Selection of single and dual-duct VAV
terminal units can involve three
elements:
1. Air Valve selection
2. Heating coil selection (if required)
3. Acoustics
Air Valve Selection
The wide open static requirement
pressure versus airflow curve is found
in the performance data section of the
catalog. To select an air valve, locate
the required design cooling airflow for
your terminal unit type and find its
vertical intersection, with the smallest
air valve size that has a pressure drop
equal to or lower than the maximum
wide open static pressure requirement.
Selection
Procedure
Single and
Dual-Duct
Terminal Units
Hot Water Heat
Select a hot water coil sufficient to
meet the design heat loss.
Selection:
Select 7.5 kW from the electric heat
table in the voltage and stages
required. The table shows the
minimum cfm allowable for the kW
selected. At 7.5 kW, the minimum
allowable airflow is 510 cfm. The
minimum cfm must be increased to
510 to assure adequate airflow over the
7.5 kW electric coil. The static pressure
requirement is shown as 0.17 in. wg.
for this example with a design cooling
flow of 1700 cfm.
Example:
VCWE, Hot Water Unit Heat, Size 17
(See air Valve Selection)
Design heating airflow:
850 cfm
Hot water flow:
1.0 GPM
Winter room design
Temperature:
T = 68 F
Design Heat Loss MBh:
Q = 25
Select hot water coil from the coil
performance table in the Performance
Data section of the catalog.
Selection:
A Standard Capacity coil is sufficient to
meet design conditions. From the Hot
Water Coil Capacity Data of the
Performance Data Section, a standard
capacity coil for a Size 17 air valve will
operate at the above conditions as
follows:
Coil Capacity:
25.7 MBh
Water pressure drop:
0.33 ft WPD
Example:
Cooling Only VCCE Terminal Unit
Design cooling airflow:
1700 cfm
Maximum wide open
air pressure drop:
0.25 in. wg
Minimum cooling airflow: 300 cfm
Air pressure drop (APD) of the hot
water coil is included in the chart
preceding the hot water coil
performance data section.
From the performance data charts,
select a valve size 17 which has a
wide open static pressure drop of
0.16 in. wg.
Electric Heat
Determine the kW required to meet
zone design heat loss.
Check the minimum and maximum
cfm desired with the minimum and
maximum cfm allowed in the table in
the general data section. The
maximum setting of 1700 cfm is within
the acceptable range. The desired
minimum setting of 300 cfm is
acceptable for the cooling only box
desired. Note that if an electric reheat
box was selected, the minimum cfm
would be dependent upon the kW of
the electric heater. (See Electric Heat
Unit Selection.)
MBh = Design Heat Loss
Heating Coil Selection (If required)
First, determine the amount of heat
required to meet space and
downstream duct heat losses from a
load calculation.
APD = 0.042 in. wg
kW = MBh / 3.414
Select nearest available kW with
voltage and steps desired from the
electric heater kW guideline table in the
Performance Data section of the
catalog.
Example:
VCEE, Electric Unit Heat, Size 17
(See Air Valve Selection)
Design heating airflow:
850 cfm
Minimum unit airflow:
300 cfm
Voltage:
277/60/1
VAC
Winter room design
temperature:
T = 68 F
Design Heat Loss:
Q = 25 MBh
kW = Q / 3.414
kW = 25 / 3.414
kW = 7.3
57
Check Leaving Air Temperature
LAT =
Q
+T
1.085 x CFM
Decide if leaving air temperature of
95.8 F is satisfactory for your
application.
LAT = 3414 x 7.5 + 68 = 95.8
1.085 x 850
Acoustics
The acoustical data found in the
Performance Data section of the VAV
catalog is used to make a
determination of the amount of noise
the terminal unit will generate. Locate
the table for the VAV terminal unit of
interest. Sound power data and an
equivalent NC level for an ARI 885-90
transfer function is listed.
Example:
VCCE, Cooling Only Terminal Unit, Size
17 (See air Valve Selection)
Cooling Airflow Cfm = 1700
Maximum inlet static
pressure:
1.5 in. wg.
Downstream static
pressure requirement:
0.30 in. wg.
Maximum NC Criteria = NC-35
Maximum Inlet Static Pressure is the
maximum static at the inlet to the box.
Downstream Static Pressure
requirement is the static loss
downstream of the VAV box, which
includes everything from the discharge
of the box to the room.
The catalog assumes 0.5 inches of
downstream static pressure for all but
the minimum inlet static pressure
valves. Since we have a downstream
static pressure loss of 0.30 inches, the
static across the box will be more than
the catalog’s assumption using 0.5
inches downstream. Look into the
catalog’s acoustic table at 1.5 + (0.5-0.3)
or 1.7 inches.

The NC level above is determined by using either the catalog’s ARI 885-90 transfer
function for the conditions shown in the acoustics table. A different transfer
function could be applied as conditions dictate.
The maximum NC level is NC-26 which is less than the maximum NC for this
example of NC-35. If the maximum NC level was exceeded, it would have been
necessary to reselect the next larger air valve size. Computer selection of VAV
terminal units greatly simplifies this task.

Notes:
1. Minimum flow and maximum flow settings must have at least a .05 delta P flow sensor signal difference.
2. Flow rings are provided with all unit sizes.
3. A minimum flow setting of zero is permissible, except for hot water and electric reheat.
4. UCM-DDC control - The minimum heating flow setting is factory set to 30% of nominal air valve flow. This is field adjustable.
5. On Model VDDE - Constant Volume = (Heat Min. + Cool Max. = Heat Max. + Cool Min.)
Example: Constant Volume = 1200 CFM
Heat Max. = 800
Cool Max. = 1200
Heat Min. = 0
Cool Min. = 400
6. Minimum cfm’s could increase due to kW requirements.

Note:
1. Fouling Factor = 0.00025
2. Capacities based on 180 F entering water and 55 F entering air temperatures. See capacity correction factors at other temperature differences.
3. The following equations may be used in calculating Leaving Air Temperature (LAT) and Water Temperature Difference (WTD).
WTD = EWT - LWT = 2 x MBH
LAT = EAT + MBH x 921.7

Notes:
1. Adequate airflow over heater is necessary. As kW requirements increase, so must minimum airflow.
The above chart indicates the minimum cfm required for each kW range.
2. Coils available with electric, electric with mercury contactors, pneumatic-electric switches and
pneumatic-electric switches with mercury contactors.
3. Available kW increments are by 0.5 kW from 0.5 to 8.0 kW, by 1.0 kW from 9.0 to 17.0 kW and by 2.0 kW
from 18.0 to 22.0 kW.
4. Each stage will be equal in kW output.
5. Single-stage and single-phase heaters are always balanced. On three-phase heaters the lineload is
unbalanced.
6. Current draw for devices is as follows. Electric actuators each draw 1.0 amp. The contactor for each
stage of heat draws 0.5 amp. The current draw for the heater elements is calculated by one of the
formulas below.
7. Minimum circuit ampacity is equal to 1.25 times the total current draw for the unit.
8. Overcurrent protective devices shall be rated for 2.25 times the total current draw of the unit

Notes:
1. Adequate airflow over heater is necessary. As kW requirements increase, so must minimum airflow.
The above chart indicates the minimum cfm required for each kW range.
2. Coils available with electric, electric with mercury contactors, pneumatic-electric switches and
pneumatic-electric switches with mercury contactors.
3. Available kW increments are by 0.5 kW from 0.5 to 8.0 kW, by 1.0 kW from 9.0 to 17.0 kW and by 2.0 kW
from 18.0 to 22.0 kW.
4. Each stage will be equal in kW output.
5. Single-stage and single-phase heaters are always balanced. On three-phase heaters the lineload is
unbalanced.
6. Current draw for devices is as follows. Electric actuators each draw 1.0 amp. The contactor for each
stage of heat draws 0.5 amp. The current draw for the heater elements is calculated by one of the
formulas below.
7. Minimum circuit ampacity is equal to 1.25 times the total current draw for the unit.
8. Overcurrent protective devices shall be rated for 2.25 times the total current draw of the unit

1. Inlet Static Pressure includes 0.5" downstream static pressure for ductwork and diffusers.
2. All data are measured in accordance with Industry Standard ARI 880.
3. All sound power levels, DB re: 10-12 Watts.
4. “MIN” inlet static pressure is the minimum primary wide open pressure drop of the unit at the specified primary airflow. Static pressures other than
minimum reflect actual presure drop across the air valve.
5. “—” represents NC levels below NC 15.
6. When using different heating and cooling air valve sizes, select acoustical data for the largest air valve. This is due to testing procedures established by
ARI 880.
7. NC Values are calculated using modeling assumptions based on ARI 885-90.

2. All data are measured in accordance with Industry Standard ARI 880.
3. All sound power levels, DB re: 10-12 Watts.
4. “MIN” inlet static pressure is the minimum primary wide open pressure drop of the unit at the specified primary airflow. Static pressures other than
minimum reflect actual presure drop across the air valve.
5. “—” represents NC levels below NC 15.
6. When using different heating and cooling air valve sizes, select acoustical data for the largest air valve. This is due to testing procedures established by
ARI 880.
7. NC Values are calculated using modeling assumptions based on ARI 885-90.

Slip and 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. The drive sides are straight
flanges which form a “U” shape. The
mating ductwork has a similar setup.
The two top and bottom pieces are
shaped like a compressed “S” with
sealant in the hollow of the “S”. These
pieces will slide over the top and
bottom straight flanges. The top and
bottom flanges of the mating ductwork
will slide into the other side of these
pieces. The two side-pieces are shaped
like a “C” and are called “Drives”.
These pieces will slide over the “U”
shaped flanges so the connection can
not be pulled apart. These pieces are
usually hammered into place. No
screws are required and by removing
the drives, the ducts may be
disconnected.

Direct Digital Controller – The
microprocessor based terminal unit
controller provides accurate, pressureindependent control through the use of
a proportional integral control
algorithm and direct digital control
technology. The controller, named the
Unit Control Module or UCM, monitors
zone temperature setpoints, zone
temperature and its rate of change and
valve airflow, using a differential
pressure signal. The controller is
provided in an enclosure with 7/8"
knockouts for remote control wiring.
A Trane UCM zone sensor is required.
UCM Zone Sensor – The UCM
controller senses zone temperature
through a sensing element located in
the zone sensor. In addition to the
sensing element, zone sensor options
may include an externally adjustable
setpoint, communications jack for use
with a portable edit device and an
override button to change the
individual controller from unoccupied
to occupied mode. The override button
has a cancel feature that will return the
system to unoccupied. Wired zone
sensors utilize a thermistor to vary the
voltage output in response to changes
in the zone temperature. Wiring to the
UCM controller must be 18 to 22 awg.
