BW437-FCU-LX Quick Guide
Disclaimer
Please read this manual before proceeding to install this controller or any other Onyxx LX device.
This manual applies to Onyxx LX UI software version 4.0 and higher and using firmware version 1.050 and higher.
All firmware updates must be done utilizing a Supplied USB-COM adapter or USB to MSTP converter cable.
Installations shall be made by a properly certified technician and respect all local mandatory codes and regulations.
Electronic controls are static sensitive devices: discharge yourself properly before manipulating and installing a controller.
Any short circuit or incorrect wiring may permanently 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 and/or alarm system to protect against failures.

1. After unpacking your BW437-FCU-LX,
unscrew the retaining screw at the
bottom of the unit.

2. Gently pull the cover away
from the base.
3. Pull the wires through the hole in
the base.

4. Connect the wires to the terminal,
referring to the chart inside the
base for the proper connections.
5. Before replacing the cover, make sure that you
have made any necessary modification to DIP
switch or jumper settings (see “Jumper Settings”).
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
Internal Jumper Settings
Jumpers setting:
JP2 to select between BO7 or AO1:
Jumper up = Using BO7 (Low Speed Fan)
Jumper down = Using AO1 (ECM)
JP3 enables EOL ( 120 Ohm ) :
Set jumpers to EOL position if this device is the
last node of the BACnet MS/TP network.
Jumper up = EOL not activated
Jumper down = EOL activated

Transformer
Add 24VAC transformer
when the power is not
supplied by the equipment
Always protect
your circuit with a
2 A fuse
Wire size based on VA rating and distance from Power source
The BW437 must be powered using a
Class 2, 24Vac transformer. When
powering from a 24Vac transformer, do not
ground either side of the transformer’s
secondary
For details on
grounding within control
panels, NFPA 79 and
UL508A provide the
required details.
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.
