Spyder® BACnet
Programmable, VAV/Unitary Controllers
INSTALLATION INSTRUCTIONS
PRODUCT DESCRIPTION
The PUB6438S, PVB6436AS and PVB6438NS controllers are
part of the Spyder family. The three 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.
These controllers are for use in VAV (Variable Air Volume) and
Unitary HVAC control applications. Each controller contains a
host micro controller to run the main HVAC application and a
second micro controller for BACnet MS/TP network
communications. Each controller has flexible, universal inputs
for external sensors, digital inputs, and a combination of
analog and digital Triac outputs. The three models are
described in Table 1. The photo to the left is the model
PVB6436AS, which includes the actuator.

controller, or in areas where escaping gas or other
explosive vapors are present. Fig. 4–Fig. 5 on
page 4 for mounting dimensions.
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 3 to begin the installation.
Mount Actuator onto Damper Shaft (PVB6436AS)
PVB6436AS controller includes 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 1-9/16 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

TYPE A DAMPER
TYPE B DAMPER
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.
Fig. 3. Determining the rotation direction (CW or CCW)
for damper opening.
Mounting Actuator Onto Damper Shaft (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
2. If the damper rotates clockwise (CW) to open, and the
90 degrees to fully close.

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 (PUB6438S and PVB6438NS)
To mount the PUB6438S or PVB6438NS controller on a DIN
rail [standard EN50022; 1-3/8 in. x 9/32 in. (7.5 mm x 35 mm)],
refer to Fig. 6 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.

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.
— Do not connect the universal input COM
terminals, analog output COM terminals or the
digital input/output COM terminals to earth
ground.
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. 8 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. 8).
NOTE: Unswitched 24 Vac power wiring can be run in the
same conduit as the BACnet MS/TP cable.

NOTES:
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.
— 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).
The earth ground terminal (terminal 3) must be
connected to a verified earth ground for each
controller in the group (see Fig. 9 on page 6).
— 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.

NOTE: Controller configurations are not necessarily limited
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,
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.
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. (1,071 m) using recommended wire. Repeaters must
be used when making runs longer than 4,000 ft. (1,071 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.
62-0310—01 6
to three devices, but the total power draw, including
accessories, cannot exceed 100 VA when powered
by the same transformer (U.S. only).
Fig. 9. Power wiring details for two or more controllers per transformer.
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 2. Example, if only DIP
switches 1, 3, 5, and 7 are enabled the MAC address
would be 85 (1 + 4 + 16 + 64 = 85).
Table 2. DIP Switch Values For MS/TP MAC Address.
DIP 7654321
VAL UE 6432168421
Setting the Device Instance Number
The Device Instance Number must be unique across the
entire BACnet system network because it is used to uniquely
identify the BACnet devices. It may be used to conveniently
identify the BACnet device from other devices during
installation. The Spyder BACnet Controllers Device Instance
Number is automatically set when it is added to a
WEBStation-AX project. The Device Instance Number can be
changed by the user, which may be necessary when
integrating with a third party or when attempting to replace an
existing controller and it is desired to maintain the existing
Device Instance Number.
To edit the Device Instance Number using WEBs AX:
1. Identify an unused Device Instance Number on the
BACnet Network, in the range of 0 - 4194302.
2. Open the Spyder Bacnet Device Mgr View
a. Double click on the BacnetNetwork located in the
Nav tree.
b. Select the Spyder Controller to be modified.
c. Click on the Edit button.
d. Enter an unused value in the Device Id field.

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.
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™ Bus
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
latest release of the Spyder Tool for WEBPro and
WEBStation.

nal, 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. 11).
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. 11).
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.
