Spyder® BACnet®
Programmable Controllers
PRODUCT DATA
The Spyder BACnet controllers require the Spyder BACnet
Programmable Feature to be licensed in the WEBpro
workbench tool and the WEBS AX JACE Controller for
programming and downloading. The Spyder BACnet Models
are also available as Individually Licensed Controllers (ILC).
The ILC versions are identical in design and capability in every
detail except for the licensing. The Individual Licensing of the
Spyder ILCs (the License is built in) allows them to be
programmed and downloaded with any brand of the Niagara
Workbench or JACE controller. The Spyder ILCs are identified
with a suffix on the Part Number of -ILC. Example:
PUB6438S-ILC follows all the same Installation Instructions
information as the PUB6438S.
These controllers are for use in VAV (Variable Air Volume),
Unitary and advanced HVAC control applications. Each
controller has flexible, universal inputs for external sensors,
digital inputs, and a combination of analog and digital Triac
outputs. All the models are described in Table 1. The photo to
the left is the model PVB6436AS, which includes the actuator.
PRODUCT DESCRIPTION
The PUB and PVB controllers are part of the Spyder family.
These controllers are BACnet MS/TP network devices
designed to control HVAC equipment. These controllers
provide many options and advanced system features that
allow state-of-the-art commercial building control. Each
controller is programmable and configurable through software.

The actuator mounts directly onto the VAV box damper shaft
and has up to 44 lb-in. (5 Nm) torque, 90-degree stroke, and 90
second timing at 60 Hz. The actuator is suitable for mounting
onto a 3/8 to 1/2 in. (10 to 13 mm) square or round VAV box
damper shaft. The minimum VAV box damper shaft length is 1-
9/16 in. (40 mm).
a
C7031G and C7041F are recommended for use with these
controllers, due to improved resolution and accuracy when
compared to the PT1000.
The two mechanical end-limit set screws control the amount of
rotation from 12° to 95°. These set screws must be securely
fastened in place. To ensure tight closing of the damper, the
shaft adapter has a total rotation stroke of 95° (see Fig. 1).
BEFORE INSTALLATION
The controller is available in three models (see Table 1).
Review the power, input, and output specifications on page 2
before installing the controller.
— Hardware driven by Triac outputs must have a minimum
current draw, when energized, of 25 mA and a maximum
current draw of 500 mA.
— Hardware driven by the analog current outputs must have a
maximum resistance of 550 Ohms, resulting in a maximum
voltage of 11 volts when driven at 20 mA.
NOTES:
1.
The actuator is shipped with the mechanical end-
limit set screws set to 95 degrees of rotation.
Adjust the two set screws closer together to
reduce the rotation travel. Each “hash mark” indi-
cator on the bracket represents approximately 6.5°
of rotation per side.
2.
The Declutch button, when pressed, allows you to
rotate the universal shaft adapter (see Fig. 1).
If resistance exceeds 550 Ohms, voltages up to 18 Vdc are
possible at the analog output terminal.
IMPORTANT
Determine the damper rotation and opening angle

The unit is shipped with the actuator set to rotate open in the
clockwise (CW) direction to a full 95 degrees. The extra 5
degrees ensures a full opening range for a 90 degree damper.
The installation procedure varies depending on the damper
opening direction and angle:
1. If the damper rotates clockwise (CW) to open, and the
angle of the damper open-to-closed is 90 degrees:
a. Manually open the damper fully (rotate clockwise).
b. Using the Declutch button, rotate the universal shaft
adapter fully clockwise.
c. Mount the actuator to the VAV damper box and shaft.
d. Tighten the two bolts on the centering clamp
(8 mm wrench; 70.8–88.5 lb-in. [8–10 Nm] torque).
When the actuator closes, the damper rotates CCW
90 degrees to fully close.

a. Manually open the damper fully (rotate clockwise).
b. The actuator is shipped with the mechanical
end-limits set at 95 degrees. Adjust the two
mechanical end-limit set screws to provide the
desired amount of rotation. Adjust the two set screws
closer together to reduce the rotation travel.
c. Tighten the two mechanical end-limit screws (Phillips

g. When the actuator closes, the damper rotates CCW
either 45 or 60 degrees to fully close.
Tools required:
— Phillips #2 screwdriver - end-limit set screw adjustment
— 8 mm wrench - centering clamp
3. If the damper rotates counterclockwise (CCW) to open, and
the angle of the damper open-to-closed is 90 degrees:
a. Manually open the damper fully (rotate counterclock-
wise).
Before mounting the actuator onto the VAV box damper shaft,
determine the following:
1. Determine the damper shaft diameter. It must be
between 3/8 in. to 1/2 in. (10 to 13 mm).
2. Determine the length of the damper shaft. If the length of
the VAV box damper shaft is less than 1-9/16 in.
(40 mm), the actuator cannot be used.
3. Determine the direction the damper shaft rotates to open
the damper (CW or CCW) (see Fig. 3). Typically, there is
an etched line on the end of the damper shaft that indi-
cates the position of the damper. In Fig. 2, the indicator
shows the damper open in a CW direction.
b. Using the Declutch button, rotate the universal shaft
adapter fully counterclockwise.
c. Mount the actuator to the damper box and shaft.
d. Tighten the two bolts on the centering clamp (8 mm
wrench; 70.8–88.5 lb-in. [8–10 Nm] torque). When
the actuator closes, the damper rotates CW
90 degrees to fully close.
4. If the damper rotates counterclockwise to open, and the
angle of the damper open-to-closed is 45 or 60 degrees:
a. Manually open the damper fully (rotate counterclock-
wise).
4. Determine the damper full opening angle (45, 60, or 90
degrees). In Fig. 2, the damper is open to its full open
position of 90 degrees.
b. The actuator is shipped with the mechanical
end-limits set at 95 degrees. Adjust the two
mechanical end-limit set screws to provide the
desired amount of rotation. Adjust the two set screws
closer together to reduce the rotation travel.
c. Tighten the two mechanical end-limit screws
(Phillips #2 screwdriver; (26.5–31 lb-in. [3.0–3.5 Nm]
torque).

NOTES:
—
Panel Mounting
The controller enclosure is constructed of a plastic base plate
and a plastic factory-snap-on cover.
Use 1/4 inch (6 mm) outside diameter, with a 0.040
in. (1 mm) wall thickness, plenum-rated 1219 FR
(94V-2) tubing.
—
Always use a fresh cut on the end of the tubing
that connects to the air flow pickups and the
restrictor ports on the controller.
NOTE: The controller is designed so that the cover does
not need to be removed from the base plate for
either mounting or wiring.
Connect the high pressure or upstream tube to the plastic
restrictor port labeled (+), and the low pressure or downstream
When twin tubing is used from the pickup, split the pickup
tubing a short length to accommodate the connections.
The controller mounts using four screws inserted through the
corners of the base plate. Fasten securely with four No. 6 or
No. 8 machine or sheet metal screws.
The controller can be mounted in any orientation. Ventilation
openings are designed into the cover to allow proper heat
dissipation, regardless of the mounting orientation.
NOTES:
—
If controllers are mounted in unusually dusty or dirty
environments, an inline, 5-micron disposable air
filter (use 5-micron filters compatible with
pneumatic controls) is recommended for the high
pressure line (marked as +) connected to the air
flow pickup.
DIN Rail Mounting (PUB1012S, PUB4024S,
PUB6438S, PVB4024NS and PVB6438NS)
To mount the PUB1012S, PUB4024S, PUB6438S,
PVB4024NS and PVB6438NS controllers on a DIN rail
[standard EN50022; 1-3/8 in. x 9/32 in. (7.5 mm x 35 mm)],
1. Holding the controller with its top tilted in towards the DIN
rail, hook the two top tabs on the back of the controller
onto the top of the DIN rail.
—
—
The tubing from the air flow pickup to the controller
should not exceed three feet (0.914 m). Any length
greater than this will degrade the flow sensing
accuracy.
Use caution when removing tubing from a connec-
tor. Always pull straight away from the connector or
use diagonal cutters to cut the edge of the tubing
attached to the connector. Never remove by pulling
at an angle.
2. Push down and in to snap the two bottom flex connectors
of the controller onto the DIN rail.

Before wiring the controller, determine the input and output
device requirements for each controller used in the system.
Select input and output devices compatible with the controller
and the application. Consider the operating range, wiring
requirements, and the environment conditions when selecting
input/output devices. When selecting actuators for modulating
applications consider using floating control. In direct digital
control applications, floating actuators will generally provide
control action equal to or better than an analog input actuator
for lower cost.

A power budget must be calculated for each device to
determine the required transformer size for proper operation. A
power budget is simply the summing of the maximum power
draw ratings (in VA) of all the devices to be controlled. This
includes the controller itself and any devices powered from the
controller, such as equipment actuators (ML6161 or other
motors) and various contactors and transducers.

•
When multiple controllers operate from a single
transformer, connect the same side of the transformer
secondary to the same power input terminal in each
device. The earth ground terminal (terminal 3) must
be connected to a verified earth ground for each
controller in the group (see Fig. 12 on page 9).
Half-wave devices and full-wave devices must not use
the same AC transformer. If a Spyder controller will
share its power supply with another device, make
sure the other device utilizes a half-wave rectifier and
that the polarity of the wiring is maintained.

Contactor
21.0
For contactors and similar devices, the in-rush power ratings
should be used as the worst case values when performing
power budget calculations. Also, the application engineer must
consider the possible combinations of simultaneously
energized outputs and calculate the VA ratings accordingly.
The worst case, which uses the largest possible VA load,
should be determined when sizing the transformer.
•
Each controller requires 24 Vac power from an energy-limited
Class II power source. To conform to Class II restrictions (U.S.
only), transformers must not be larger than 100 VA. A single
transformer can power more than one controller.
POWER BUDGET CALCULATION EXAMPLE
Table 3 is an example of a power budget calculation for a
typical PVB6436AS controller. While the example is shown for
only this model, the process is applicable for all controller
models.
GUIDELINES FOR POWER WIRING ARE AS FOLLOWS:
—
For multiple controllers operating from a single
transformer, the same side of the transformer
secondary must be connected to the same power input
terminal in each device. The earth ground terminal
must be connected to a verified earth ground for each
controller in the group (see Fig. 12 on page 9).
Controller configurations are not necessarily limited to
three devices, but the total power draw, including
accessories, cannot exceed 100 VA when powered by
the same transformer (U.S. only).

Many controllers require all loads to be powered by the
same transformer that powers the controller.
Keep the earth ground connection wire run as short as
possible (refer to Fig. 11–Fig. 12 beginning on page 9).
Do not connect earth ground to the controller’s digital or

Line-Loss
The system example above requires 30.7 VA of peak power.
Therefore, a 100 VA AT92A transformer could be used to
power one controller of this type. Because the total peak power
Controllers must receive a minimum supply voltage of 20 Vac.
If long power or output wire runs are required, a voltage drop
due to Ohms Law (I x R) line-loss must be considered. This
line-loss can result in a significant increase in total power

required and thereby affect transformer sizing. The following
example is an I x R line-loss calculation for a 200 ft. (61m) run
from the transformer to a controller drawing 37 VA and using
two 18 AWG (1.0 sq mm) wires.
With 100 percent load, the transformer secondary must supply
between 23 and 25 volts to meet the NEMA standard. When a
purchased transformer meets the NEMA standard DC20-1986,
the transformer voltage regulating ability can be considered
reliable. Compliance with the NEMA standard is voluntary.
The formula is:
Loss = [length of round-trip wire run (ft.)] x [resistance in
wire (ohms per ft.)] x [current in wire (amperes)]

From specification data:
18 AWG twisted pair wire has a resistance of 6.52 ohms per
1000 feet.
Loss = [(400 ft.) x (6.52/1000 ohms per ft.)] x [(37 VA)/(24V)]
= 4.02 volts

This means that four volts are going to be lost between the
transformer and the controller. To assure the controller
receives at least 20 volts, the transformer must output more
than 24 volts. Because all transformer output voltage levels
depend on the size of the connected load, a larger transformer
outputs a higher voltage than a smaller one for a given load.
Fig. 10 shows this voltage load dependence.

% OF LOAD
In the preceding I x R loss example, even though the controller
load is only 37 VA, a standard 40 VA transformer is not
sufficient due to the line-loss. Looking at Fig. 10, a 40 VA
transformer is just under 100 percent loaded (for the 37 VA
controller) and has a secondary voltage of 22.9 volts. (Use the
lower edge of the shaded zone in Fig. 10 that represents the
worst case conditions.) When the I x R loss of four volts is
subtracted, only 18.9 volts reaches the controller. This is not
enough voltage for proper operation.

VA Rating
In this situation, the engineer has three alternatives:
1. Use a larger transformer. For example, if an 80 VA model
is used, an output of 24.4 volts, minus the four volt line-
loss, supplies 20.4V to the controller (see Fig. 10).
Although acceptable, the four-volt line-loss in this exam-
ple is higher than recommended.

NOTE: The AT88A and AT92A transformers do not meet
the voluntary NEMA standard DC20-1986.
IMPORTANT
No installation should be designed where the line-loss
is greater than two volts. This allows for nominal oper-
ation if the primary voltage drops to 102 Vac (120 Vac
minus 15 percent).
Wiring
All wiring must comply with applicable electrical codes and
ordinances, or as specified on installation wiring diagrams.
Controller wiring is terminated to the screw terminal blocks
located on the top and the bottom of the device.
2. Use heavier gauge wire for the power run. 14 AWG
(2.0 sq mm) wire has a resistance of 2.57 ohms per
1,000 ft. Using the preceding formula results in a line-
loss of only 1.58 volts (compared with 4.02 volts). This
would allow a 40 VA transformer to be used. 14 AWG
(2.0 sq mm) wire is the recommended wire size for 24
Vac wiring.
WARNING
Electrical Shock Hazard.
3. Locate the transformer closer to the controller. This
reduces the length of the wire run, and the line-loss.
Can cause severe injury, death or property damage.
Disconnect power supply before beginning wiring or
making wiring connections, to prevent electrical shock
or equipment damage.
The issue of line-loss is also important in the case of the output
wiring connected to the Triac digital outputs. The same formula
and method are used. Keep all power and output wire runs as
short as practical. When necessary, use heavier gauge wire, a
bigger transformer, or install the transformer closer to the
controller.
NOTES:
—
For multiple controllers operating from a single
transformer, the same side of the transformer
secondary must be connected to the same power
input terminal in each controller. Controller
configurations will not necessarily be limited to
three devices, but the total power draw, including
accessories, cannot exceed 100 VA when
To meet the National Electrical Manufacturers Association
(NEMA) standards, a transformer must stay within the NEMA

Setting the MS/TP MAC address
Termination Resistors
The MS/TP MAC address for each device must be set to a
unique value in the range of 0-127 on an MS/TP network
segment (address 0, 1, 2, & 3 should be avoided as they are
commonly used for the router, diagnostic tools, and as spare
addresses). DIP switches on the Spyder BACnet controller are
used to set the controller's MAC address.
Matched terminating resistors are required at each end of a
segment bus wired across (+) and (-). Use matched precision
resistors rated 1/4W ±1% / 80 - 130 Ohms. Ideally, the value of
the terminating resistors should match the rated characteristic
impedance of the installed cable. For example, if the installed
MS/TP cable has a a listed characteristic impedance of 120
Ohm, install 120 Ohm matched precision resistors.
To set the MS/TP MAC address of a Spyder BACnet controller:
1. Find an unused MAC address on the MS/TP network to
which the Spyder BACnet controller connects.
2. Locate the DIP switch bank on the Spyder BACnet for
addressing. This is labeled MAC Address
3. With the Spyder BACnet Controller powered down, set
the DIP switches for the MAC Address you want. Add the
value of DIP switches set to ON to determine the MAC
address. See Table 6. Example, if only DIP switches 1, 3,
5, and 7 are enabled the MAC address would be 85 (1 +
4 + 16 + 64 = 85).
NOTE: The controller does not provide any network bias-
ing.
Shield Terminating
Following proper MS/TP cabling shield grounding procedures
is important to minimize the risk of communication problems
and equipment damage caused by capacitive coupling.
Capacitive coupling is caused by placing MS/TP cabling close
to lines carrying higher voltage. The shield should be grounded
on only one end of the MS/TP segment (typically the router
end). Tie the shield through using the SHLD (terminal 4) on the
Spyder BACnet Controller.

Sylk is a two wire, polarity insensitive bus that provides both 18
VDC power and communications between a Sylk-enabled
sensor and a Sylk-enabled controller. Using Sylk-enabled
sensors saves I/O on the controller and is faster and cheaper
to install since only two wires are needed and the bus is
polarity insensitive. Sylk sensors are configured using the

CHECKOUT
Step 1. Check Installation and Wiring
Inspect all wiring connections at the controller terminals, and
verify compliance with installation wiring diagrams. If any wiring
changes are required, first be sure to remove power from the
controller before starting work. Pay particular attention to:
— 24 Vac power connections. Verify that multiple controllers
being powered by the same transformer are wired with the
transformer secondary connected to the same input
terminal numbers on each controller. Use a meter to
measure 24 Vac at the appropriate terminals (see Fig. 12
on page 9). Controller configurations are not necessarily
limited to three devices, but the total power draw, including
accessories, cannot exceed 100 VA when powered by the
same transformer (U.S. only).
— Be sure that each controller has terminal 3 wired to a
verified earth ground, using a wire run as short as possible
with the heaviest gauge wire available, up to 14 AWG (2.0
sq mm) with a minimum of 18 AWG (1.0 sq mm) for each
controller in the group (see Fig. 12 on page 9).
— Check that the MS/TP network polarity has been connected
properly on each controller. BACnet MS/TP is polarity
sensitive; communication will be lost for the entire segment

The MS/TP MAC address DIP switches are used to set the
unit's MAC address. Each Spyder BACnet on an MS/TP
network must have a unique MAC address in the range of 0-
127 (address 0 should be avoided as it is the Honeywell factory
default MAC address for all MS/TP devices).
CONTROLLER STATUS LED:
The LED on the front of the controller provides a visual
indication of the status of the device. When the controller
receives power, the LED appears in one of the following
allowable states, as described in Table 8.

BACNET STATUS LED:
IMPORTANT
The LED on the front of the controller, between the BACnet
MS/TP terminals and MAC Address DIP Switches, provides a
visual indication of the BACnet MS/TP communication status.
When the controller receives power, the LED appears in one of
the following allowable states, as described in Table 9.
To prevent bending or breaking the alignment pins on
longer terminal blocks, insert the screwdriver at
several points to evenly and gradually lift up the
terminal block.
Insert the screwdriver blade no more than 1/8 in.
(3 mm) to prevent damage to the terminal block align-
ment pins on the controller circuit board.
