GENERAL
The LYNX controllers CLLYUL1012S, CLLYUL4024S,
CLLYUL6438S, CLLYVL0000AS, CLLYVL4022AS,
CLLYVL4024NS, CLLYVL6436AS, and CLLYVL6438NS are
part of the LYNX family. They are Free Topology Transceiver
(FTT) L
ONMARK®-compliant devices designed to control
HVAC equipment.
LYNX controllers provide many options and advanced system
features that allow state-of-the-art commercial building
control. Each LYNX controller is programmable and configurable through software.
LYNX controllers are designed for use in VAV (Variable Air
Volume) and Unitary HVAC control applications. Each controller contains a host microcontroller to run the main HVAC
application and a second microcontroller for L
network communications. Each controller has flexible, universal inputs for external sensors, digital inputs, and a mix of
analog and digital triac outputs (see Table 1). The accompanying image is of the model CLLYVL6436AS, which
includes an actuator.

BEFORE INSTALLATION
The controller is available in eight models (see Table 1).
Before installing the controller, review the power, input, and
output specifications in section “Technical Data”.
Hardware driven by Triac outputs must have a min.
current draw, when energized, of 25 mA and a max.
current draw of 500 mA.
Hardware driven by the analog current outputs must have
a max. resistance of 550 Ω, resulting in a max. voltage of
11 V when driven at 20 mA. If resistance exceeds 550 Ω,
voltages up to 18 Vdc are possible at the analog output
terminal.
WARNING
Electrical Shock Hazard.
Can cause severe injury, death or property
damage.
To prevent electrical shock or equipment damage,
disconnect power supply before beginning wiring or
making wiring connections.
INSTALLATION
The controller must be mounted in a position that allows
clearance for wiring, servicing, removal, connection of the
L
ONWORKS® Bus Jack and access to the Neuron® Service
Pin (see Fig. 13).
The controller may be mounted in any orientation.

IMPORTANT
Avoid mounting in areas where acid fumes or other
deteriorating vapors can attack the metal parts of the
controller, or in areas where escaping gas or other
explosive vapors are present. See Fig. 4 and Fig. 7 for
mounting dimensions.
In the case of the CLLYVL0000AS, CLLYVL4022AS, and
CLLYVL6436AS models, first the actuator and then the
controller is mounted. For the other models, see section
“Mount Controller” on page 4 to begin the installation.
Mounting Actuator onto Damper Shaft
(Models with Actuator)
The CLLYVL0000AS, CLLYVL4022AS, and CLLYVL6436AS
controllers include the direct-coupled actuator with
DECLUTCH button, which is shipped hard-wired to the
controller.
The actuator mounts directly onto the VAV box damper shaft
and has up to 5 Nm torque, 90° stroke, and 90-sec timing at
60 Hz. The actuator is suitable for mounting onto a 10 to 13
mm square or round VAV box damper shaft. The min. VAV
box damper shaft length is 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).
NOTE 1: The actuator is shipped with the mechanical end

Before Mounting Actuator onto Damper
Shaft (Models with Actuator)
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
10…13 mm.
2. Determine the length of the damper shaft. If the length of
the VAV box damper shaft is less than 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 indicating
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°).
In Fig. 2, the damper is open to its full open position of
90°.

Mounting Actuator Onto Damper Shaft
(Models with Actuator)
The unit is shipped with the actuator set to rotate open in the
clockwise (CW) direction to a full 95°. The extra 5° ensures a
full opening range for a 90° damper.
The installation procedure varies depending on the damper
opening direction and angle:
1) If the damper rotates CW to open, and the angle of the
damper open-to-closed is 90°:
a) Manually open the damper fully (rotate CW).
b) Using the DECLUTCH button, rotate the universal
shaft adapter fully CW.
c) Mount the actuator to the VAV damper box and shaft.
d) Tighten the two bolts on the centering clamp (8 mm
wrench; 8...10 Nm torque). When the actuator closes,
the damper rotates CCW 90° to fully close.
2) If the damper rotates CW to open, and the angle of the
damper open-to-closed is 45 or 60°:
a) Manually open the damper fully (rotate CW).
b) The actuator is shipped with the mechanical end-limits
set at 95°. 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; (3.0-3.5 Nm torque).
d) Using the DECLUTCH button, rotate the universal
shaft adapter fully CW.
e) Mount the actuator to the VAV damper box and shaft.
f) Tighten the two bolts on the centering clamp (8 mm
wrench; 8...10 Nm torque).
g) When the actuator closes, the damper rotates CCW
either 45 or 60° to fully close.
3) If the damper rotates CCW to open, and the angle of the
damper open-to-closed is 90°:
a) Manually open the damper fully (rotate CCW).
b) Using the DECLUTCH button, rotate the universal
shaft adapter fully CCW.
c) Mount the actuator to the damper box and shaft.
d) Tighten the two bolts on the centering clamp (8 mm
wrench; 8...10 Nm torque). When the actuator closes,
the damper rotates CW 90° to fully close.
4) If the damper rotates CCW to open, and the angle of the
damper open-to-closed is 45 or 60°:
a) Manually open the damper fully (rotate CCW).
b) The actuator is shipped with the mechanical end-limits
set at 95°. 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; (3.0-3.5 Nm torque).
d) Using the DECLUTCH button, rotate the universal
shaft adapter fully CCW.
e) Mount the actuator to the VAV damper box and shaft.
f) Tighten the two bolts on the centering clamp (8 mm
wrench; 8...10 Nm torque).
g) When the actuator closes, the damper rotates CW
either 45 or 60° 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
To avoid the possibility of over-pressurizing the duct
work on fan start-up, it is advisable to leave the
dampers in an open position after installation. To
prevent over-pressurization in the duct work on fan
start-up, use the DECLUTCH button (see Fig. 1) to
open the box damper on powered-down controllers. To
declutch, press and hold the DECLUTCH button, thus
disengaging the motor. Turn the damper shaft until the
damper is open and then release the DECLUTCH
button. When power is restored to the controller, the
controller synchronizes the damper actuator, so that
the damper is in the correct position upon start-up.

Air Flow Pick-Up
For CLLYVL0000AS, CLLYVL4022AS, and CLLYVL6436AS
and CLLYVL6438NS, connect the air flow pickup to the two
restrictor ports on the controller (see Fig. 9).
NOTE 1: Use tubing with 6 mm outside diameter and 1 mm
wall thickness.
NOTE 2: 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 (+), and the low-pressure or downstream tube to the restrictor port labeled (-). See labeling in
Fig. 9. When twin tubing is used from the pickup, split the
pickup tubing a short length to accommodate the connections.
NOTE 1: 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 highpressure line (marked as +) connected to the air
flow pickup.
NOTE 2: The tubing from the air flow pickup to the controller
should not exceed 1 m. Any length greater than
this will degrade the flow sensing accuracy.
NOTE 3: Use caution when removing tubing from a con-
nector. 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. See
Fig. 16 through Fig. 22 for typical controller wiring configurations.
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 controllers that are required for optimum system wide
operation. Typical examples include 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. See 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 sum of the max. 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 and various
contactors and transducers.
IMPORTANT
If a controller is used on Heating and Cooling
Equipment (UL 1995; U.S., only) and transformer
primary power is more than 150 volts, connect the
transformer secondary common to earth ground (see
Fig. 10).
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. 11).
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.
WARNING
Electrical Shock Hazard.
Can cause severe injury, death or property
damage.
To prevent electrical shock or equipment damage,
disconnect power supply before beginning wiring or
making wiring connections.
NOTE 1: 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 power
and wiring recommendations, See section “Power”
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. 11).
NOTE 2: All loads on the controller must be powered by the
same transformer powering the controller itself. A
controller can use separate transformers for controller power and output power.
NOTE 3: Keep the earth ground connection (terminal 3) wire
run as short as possible.
NOTE 4: Do not connect the universal input COM terminals,
analog output COM terminals or the digital
input/output COM terminals to earth ground. See
Fig. 15 through Fig. 20 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. 10 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

IMPORTANT
If the controller is not connected to a good earth
ground, the controller's internal transient protection
circuitry is compromised and the function of protecting
the controller against noise and power line spikes
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 terminal arrangements similar to the
examples shown in Fig. 13 and Fig. 14 as described in Table
3 and Table 4.

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.
11). 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).
Ensure 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 2.0 mm
a min. of 1.0 mm
2
for each controller in the group (see Fig.
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
section “Power” on page 6.
The installation wiring diagrams should indicate the locations
for 209541B termination module(s). See Fig. 12 and refer to
Excel 50/500/800 L
ONWORKS® Mechanisms (EN0B-
0270GE51).
Correct placement of the end-of-line termination resistors is
required for proper L
ONWORKS® Bus communications.

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.
b. For long terminal blocks (6 or more terminals), insert
screwdriver blade on one side of the terminal block
and gently rotate the blade ¼ turn. Then, move to the
other side of the terminal block and do the same.
Repeat until the terminal block is evenly raised from its
alignment pins.
2. Once the terminal block is raised 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.
