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.

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.
If resistance exceeds 550 Ohms, voltages up to 18 Vdc are
possible at the analog output terminal.
Electrical Shock Hazard.
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.
INSTALLATION
The controller must be mounted in a position that allows
clearance for wiring, servicing, removal, connection of the
BACnet MS/TP Molex connector and access to the MS/TP
MAC address DIP switches (see Fig. 15 on page 12).
For the PVB6436AS model, the actuator is mounted first and
then the controller is mounted. For the other models, go to
“Mount Controller” on page 5 to begin the installation.
Mount Actuator onto Damper Shaft (PVB0000AS, PVB4022AS and PVB6436AS)
PVB0000AS, PVB4022AS and PVB6436AS controllers include
the direct-coupled actuator with Declutch mechanism, which is
shipped hard-wired to the controller.
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 19/16 in. (40 mm).
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).
NOTES:
1. The actuator is shipped with the mechanical endlimit set screws set to 95 degrees of rotation.
Adjust the two set screws closer together to
reduce the rotation travel. Each “hash mark” indicator 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).
IMPORTANT
Determine the damper rotation and opening angle
prior to installation. See Fig. 2 below and Fig. 3 on
page 4 for examples.

Before Mounting Actuator onto Damper
Shaft (PVB0000AS, PVB4022AS and
PVB6436AS)
Tools required:
— Phillips #2 screwdriver - end-limit set screw adjustment
— 8 mm wrench - centering clamp
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 indicates the position of the damper. In Fig. 2, the indicator
shows the damper open in a CW direction.
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.

Mounting Actuator Onto Damper Shaft
(PVB0000AS, PVB4022AS and PVB6436AS)
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.
2. If the damper rotates clockwise (CW) to open, and the
angle of the damper open-to-closed is 45 or 60 degrees:
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
#2 screwdriver; (26.5–31 lb-in. [3.0–3.5 Nm] torque).
d. Using the Declutch button, rotate the universal shaft
adapter fully clockwise.
e. Mount the actuator to the VAV damper box and shaft.
f. Tighten the two bolts on the centering clamp
(8 mm wrench; 70.8–88.5 lb-in. [8–10 Nm] torque).
g. When the actuator closes, the damper rotates CCW

either 45 or 60 degrees to fully close.
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).
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.
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).
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).
d. Using the Declutch button, rotate the universal shaft
adapter fully counter-clockwise.
e. Mount the actuator to the VAV damper box and shaft.
f. Tighten the two bolts on the centering clamp
(8 mm wrench; 70.8–88.5 lb-in. [8–10 Nm] torque).
g. When the actuator closes, the damper rotates CW
either 45 or 60 degrees to fully close.

IMPORTANT
Special precautions must be taken for dampers that
open in a CCW direction. The actuator is shipped with
its rotation direction set to CW to Open, which applies
to the damper direction in steps 1 and 2 above. If the
damper shaft rotates in the CCW direction to open, the
controller software must be programmed to change
the rotation to “Reverse to Open,” which applies to the
damper direction in steps 3 and 4 above.
IMPORTANT
It is advisable to leave the dampers in an open
position after installation to avoid the possibility of
over-pressurizing the duct work on fan startup. Use
the Declutch button (see Fig. 1 on page 3) to open the
box damper on controllers that are powered down, to
prevent over-pressurization in the duct work on fan
startup. To Declutch, press and hold the button to
disengage the motor. Turn the damper shaft until the
damper is open and release the button. When power
is restored to the controller, the controller
synchronizes the damper actuator, so that the damper
is in the correct position upon startup.
Mount Controller
NOTE: The controller may be wired before mounting to a
panel or DIN rail.
Terminal blocks are used to make all wiring connections to the
controller. Attach all wiring to the appropriate terminal blocks
(see “Wiring” on page 8).

Panel Mounting
The controller enclosure is constructed of a plastic base plate
and a plastic factory-snap-on cover.
NOTE: The controller is designed so that the cover does
not need to be removed from the base plate for
either mounting or wiring.
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.
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)],
refer to Fig. 8 and perform the following steps:
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.
2. Push down and in to snap the two bottom flex connectors
of the controller onto the DIN rail.
IMPORTANT
To remove the controller from the DIN rail, perform the
following:
1. Push straight up from the bottom to release the top
tabs.
2. Rotate the top of the controller out towards you and
pull the controller down and away from the DIN rail to
release the bottom flex connectors.
NOTES:
— 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.
Connect the high pressure or upstream tube to the plastic
restrictor port labeled (
tube to the restrictor port labeled (
+), and the low pressure or downstream
-). See labeling in Fig. 9.
When twin tubing is used from the pickup, split the pickup
tubing a short length to accommodate the connections.
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)
pressure line (marked as
is recommended for the high
+
) connected to the air
flow pickup.
— 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.

Power
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.
Determine the location of controllers, sensors, actuators and
other input/output devices and create wiring diagrams. Refer to
Fig. 17–Fig. 23 beginning on page 14 for illustrations of typical
controller wiring for various configurations.
SPYDER® BACNET® PROGRAMMABLE CONTROLLERS
The application engineer must review the control job
requirements. This includes the sequences of operation for the
controller, and for the system as a whole. Usually, there are
variables that must be passed between the controller and other
Spyder BACnet controller(s) that are required for optimum
system wide operation. Typical examples are the TOD, Occ/
Unocc signal, the outdoor air temperature, the demand limit
control signal, and the smoke control mode signal.
It is important to understand these interrelationships early in
the job engineering process, to ensure proper implementation
when configuring the controllers. Refer to the controller
Application Guides.
Power Budget
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.
IMPORTANT
• 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.
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.

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.
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).
— See Fig. 11 on page 9 for controller power wiring used
in UL 1995 equipment (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
analog ground terminals (refer to Fig. 11 and Fig. 12).
— Unswitched 24 Vac power wiring can be run in the
same conduit as the L
ONWORKS® Bus cable.
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
Line-Loss
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.
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.
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.
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 lineloss, supplies 20.4V to the controller (see Fig. 10).
Although acceptable, the four-volt line-loss in this example is higher than recommended.
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.
Fig. 10. NEMA Class 2 transformer voltage output limits.
The Honeywell transformers listed in Table 5 meet the NEMA
standard DC20-1986.

NEMA standard DC20-1986.

AT72D 40
AT87A 50
AK3310 Assembly 100
IMPORTANT
No installation should be designed where the line-loss
is greater than two volts. This allows for nominal operation if the primary voltage drops to 102 Vac (120 Vac
minus 15 percent).
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 lineloss 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.
3. Locate the transformer closer to the controller. This
reduces the length of the wire run, and the line-loss.
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.
To meet the National Electrical Manufacturers Association
(NEMA) standards, a transformer must stay within the NEMA
limits. The chart in Fig. 10 shows the required limits at various
loads.
63-2689—05 8
NOTE: The AT88A and AT92A transformers do not meet
the voluntary NEMA standard DC20-1986.
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.
Electrical Shock Hazard.
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.
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
powered by the same transformer (U.S. only). For

on page 6. 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).
— All loads on the controller must be powered by the
same transformer that powers the controller itself.
A controller can use separate transformers for
controller power and output power.
— Keep the earth ground connection (terminal 3) wire
run as short as possible.
— Do not connect the universal input COM terminals,
analog output COM terminals or the digital input/
output COM terminals to earth ground. Refer to
Fig. 16–Fig. 21 beginning on page 13 for wiring
examples.
The 24 Vac power from an energy limited Class II power
source must be provided to the controller. To conform to Class
II restrictions (U.S. only), the transformer must not be larger
than 100 VA.
Fig. 11 depicts a single controller using one transformer.
IMPORTANT
Power must be off prior to connecting to or removing
connections from the 24 Vac power (24 Vac/24 Vac
COM), earth ground (EGND), and 20 Vdc power (20
Vdc) terminals.
IMPORTANT
Use the heaviest gauge wire available, up to 14 AWG
(2.0 sq mm), with a minimum of 18 AWG (1.0 sq mm),
for all power and earth ground wiring.
Screw-type terminal blocks are designed to accept up
to one 14 AWG (2.0 sq mm) conductor or up to two 18
AWG (1.0 sq mm) conductors. More than two wires
that are 18 AWG (2.0 sq mm) can be connected with
a wire nut. Include a pigtail with this wire group and
attach the pigtail to the terminal block.
IMPORTANT
Connect terminal 2, (the 24 Vac common [24 VAC
COM] terminal) to earth ground (see Fig. 11).
NOTE: Unswitched 24 Vac power wiring can be run in the
same conduit as the L
ONWORKS® cable.
Fig. 11. Power wiring details for one controller per
transformer.
More than one controller can be powered by a single
transformer. Fig. 12 shows power wiring details for multiple
controllers.
NOTE: Controller configurations are not necessarily lim-
ited to three devices, but the total power draw,
including accessories, cannot exceed 100 VA
when powered by the same transformer (U.S.
only). For power wiring recommendations, see
“Power” on page 6.
Communications
Each controller uses a BACnet MS/TP communications port.
The controller’s data is presented to other controllers over a
twisted-pair MS/TP network, which uses the EIA-485 signaling
standard capable of the following baud rates: 9.6, 19.2, 38.4,
Fig. 12. Power wiring details for two or more controllers per transformer.
76.8 or 115.2 kilobits per second (configured at global
controller). The Spyder BACnet controllers are master devices
on the MS/TP network. Each Spyder BACnet controller uses a
high-quality EIA-485 transceiver and exerts 1/4 unit load on the
MS/TP network.
9 63-2689—05
SPYDER® BACNET® PROGRAMMABLE CONTROLLERS
Cabling should be selected that meets or exceeds the BACnet
Standard which specifies the following: An MS/TP EIA-485
network shall use shielded, twisted-pair cable with
characteristic impedance between 100 and 130 ohms.
Distributed capacitance between conductors shall be less than
100 pF per meter (30 pF per foot). Distributed capacitance
between conductors and shield shall be less that 200 pF per
meter (60 pF per foot). Foil or braided shields are acceptable.
The Honeywell tested and recommended MS/TP cable is
Honeywell Cable 3322 (18 AWG, 1-Pair, Shielded, Plenum
cable), alternatively Honeywell Cable 3251 (22 AWG, 1-Pair,
Shielded, Plenum cable) is available and meets the BACnet
Standard requirements (www.honeywellcable.com).
The maximum BACnet MS/TP network Bus segment length is
4,000 ft. (1,219 m) using recommended wire. Repeaters must
be used when making runs longer than 4,000 ft. (1,219 m). A
maximum of three repeaters can be used between any two
devices.
Setting the MS/TP MAC address
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.
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: See Fig. 15 on page 12 for DIP switch orienta-
tion and arrangement.

Termination Resistors
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.
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.

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

Electrical Shock Hazard.
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.
NOTE: When attaching two or more wires to the same
terminal, other than 14 AWG (2.0 sq mm), be sure
to twist them together. Deviation from this rule
can result in improper electrical contact (see Fig.
14).
Each terminal can accommodate the following gauges of wire:
— Single wire: from 22 AWG to 14 AWG solid or stranded
— Multiple wires: up to two 18 AWG stranded, with 1/4 watt
wire-wound resistor
Prepare wiring for the terminal blocks, as follows:
1. Strip 1/2 in. (13 mm) insulation from the conductor.
2. Cut a single wire to 3/16 in. (5 mm). Insert the wire in the
required terminal location and tighten the screw.
3. If two or more wires are being inserted into one terminal
location, twist the wires together a minimum of three
turns before inserting them (see Fig. 14).
4. Cut the twisted end of the wires to 3/16 in. (5 mm) before
inserting them into the terminal and tightening the screw.
5. Pull on each wire in all terminals to check for good
mechanical connection.

Wiring Details
Each controller is shipped with the digital outputs, which switch
the 24 Vac to the load (High Side).
The three analog outputs (AO) are used to control modulating
heating, cooling and economizer equipment. Any AO may be
used as a digital output, as follows:
— False (0%) produces 0 Vdc, (0 mA)
— True (100%) produces the maximum 11 Vdc (22 mA)

cannot be fulfilled. This could result in a damaged circuit board and require replacement of the controller.
Refer to installation diagrams for specific wiring.
All controllers have the terminal arrangements similar to the
examples shown in Fig. 15 as described in Table Table 7 on
page 12.
MS/TP MAC ADDRESS DIP SWITCHES
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 0127 (address 0 should be avoided as it is the Honeywell factory
default MAC address for all MS/TP devices).
MS/TP SERVICE CONNECTOR PINS
Local device MS/TP network connection is provided via the
molex connector pins (0.100-in. molex connector—part
number: 22-01-2035).

page 11).
— Verify that Triac wiring of the digital outputs to external
devices uses the proper load power and 24 Vac common
terminal (digital output common terminals) for High-Side
switching.
NOTE: All wiring must comply with applicable electrical
codes and ordinances or as specified on installation wiring diagrams.
For guidelines for wiring run lengths and power budget, see
“Power” on page 6.
VERIFY END-OF-LINE TERMINATION RESISTOR
PLACEMENT
The installation wiring diagrams should indicate the locations
for placement of the end of line termination resistors. See
Fig. 13 on page 11.
Correct placement of the end-of-line termination resistors is
required for proper L
ONWORKS® Bus communications.

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

SET THE MS/TP MAC ADDRESS
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 0127 (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.

Terminal Block Removal
To simplify controller replacement, all terminal blocks are
designed to be removed with the wiring connections intact and
then re-installed on the new controller. See Fig. 24 and refer to
the following procedure:
IMPORTANT
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 alignment pins on the controller circuit board.
Fig. 24. Removing Terminal Blocks.
1. Use a thin-bladed screwdriver to evenly raise the
terminal block from its alignment pins:
a. For short terminal blocks (1 to 5 terminals), insert
screwdriver blade in the center of the terminal block
and use a back and forth twisting motion to gently
raise the terminal block from its alignment pins 1/4 in.
(6.35 mm).
b. For long terminal blocks (6 or more terminals), insert
screwdriver blade on one side of the terminal block
and gently rotate the blade 1/4 turn. Then, move to
the other side of the terminal block and do the same.
Repeat until the terminal block is evenly raised 1/4 in.
(6.35 mm) from its alignment pins.

2. Once the terminal block is raised 1/4 in. (6.35 mm) from
its alignment pins, grasp the terminal block at its center
(for long terminal blocks grasp it at each end) and pull it
straight up.
