Controller Installation and Wiring Guide
BZ122-LX - Configurable VAVMS/TP
Controller Disclaimer Notes
Please read the manual before proceeding to install this controller or any other Onyxx LX device. This manual applies to
Onyxx LX U I software version 4.0 and higher and using
firmware
version
2
.182 and higher.
All firmware updates must be done utilizing Supplied USB-COM adapter or USB to MSTP converter cable.
Installations shall be made by a certified technician and respect all local codes and regulations.
Electronic controls are static sensitive devices: discharge yourself properly before handling and installing a controller.
Any short circuit or incorrect wiring may damage the controller or the controlled equipment.
Double check all wiring before applying power.
If a control failure could lead to personal injury and/or loss of property, it becomes the responsibility of the installer to
add safety devices to protect against failures

Electronic controls are static sensitive devices; discharge yourself properly before manipulating and installing the device.
Short circuits or incorrect wiring may permanently damage the controller. Double check your wiring before applying power.
If acontrol failure could lead to personal injury and/or loss of property, the installer must add safety devices and/or alarm
systems to protect against failures.
Installation
BZ122-LX Mounting Instructions
Failure to properly position the screw will result in torsion and breakage of the unit.
When securing the BZ122 to the
ductwork or sheet metal, make sure that
the rotor shaft bracket is centered, and
the mounting screw is in the center of
the slider. Because the clamp fixes to
the shaft asymmetrically, this allows the
unit to move with the shaft as the
bracket slides back and forth.

The BZ122-LX consists of an
actuator motor and various screw
terminals, and jumpers, that let you
configure the unit to your needs.
Jumpers are within the housing
(internal), under the removable
cover.Internal labeling inside the
cover helps you identify the
interfaces
Physical connectors (for mounting
and cable connections) are
accessible on the outside of the
unit. This section describes all the
user adjustable interfaces of the
BZ122-LX.Details for each section
are provided further in this guide.

Cables suitable for use in an RS-485 network should have an impedance of between 100 and 130
ohms, a capacitance between conductors of less than 30 pF per foot (100 pF per meter), and a
capacitance between conductors and shield less than 60 pF per foot (200 pF per meter).

The BZ122 is powered using a
Class 2, 24Vac transformer,, do not
ground either side of the
transformer’s secondary
WARNING: Internally, this device utilizes a half-wave rectifier
and therefore can only share the same AC power source with
other half-wave rectified devices. Sharing AC power with full
wave rectified devices is NOT recommended. If not properly
wired, connecting controllers on an MSTP BACnet network
that have internal full wave rectifier controllers with Onyxx LX
half-wave controllers can have adverse effect on network
communications and in some cases would result in damaging
the Onyxx LX Controllers. Not properly wiring the devices will
void the warranty.
For maximum protection from
electrostatic discharge or other
forms of EMI connect each
controller to earth ground using a
#16 AWG and keep these wires as
short as possible.
Proper grounding of a controller is
important to ensure a high probability of
surviving a nearby lightning strike as well as
other possible electrical surges.
For details on
grounding within control
panels, NFPA 79 and
UL508A provide the
required details.

TZ Room Sensor Wiring
•Daisy Chain up to 3 TZ room sensors. All TZroom sensors must be the same model, either all
TZ200 or all TZ100.
•RS-485 Wire Required for communications wiring
•Supported Wire Size 28-16AWG for power wiring, recommend 18 AWG
•Max total distance of communication wire of 300 ft from controller to last TZroom sensor.
•

•
•
Field verifyTzone addressing and EOL jumpers
Connect shields together in thedaisy chain communication network(isolatethem to avoid touching
metal or electronic components)
Connectshield toground, at only one extremityof the network
MS/TPA+ and B+ are optional;they are directly connected to the USB connector below theTZxxx.
The goal is to allowaccess to the MSTPnetwork from the special USB to MSTP adapter.
•If there is a loss in communication to any of the TZcontrollers, BV24 will indicate a fault, AV 41 will
=- 40 °F and the fan, heating and cooling will be disabled, and the damper will return to minimum
position.
