Set up Network Communications
Set up Network Communications
Set up the Unit for Network Control
After the communication module has been installed, the
next step is to configure the unit controller for network
control. Follow the instructions below to set the BAS network
protocol from the MicroTech II chiller unit controller keypad or
touchscreen interface. Once the protocol has been set, the
communication module can then be configured for your specific
BACnet network requirements.
Network Setup for Centrifugal Chillers
1. Disable the chiller. The chiller should not be operating
while performing this procedure.
2. At the chiller unit controller keypad display:
a. Change the Set/Unit Setpoint menu Protocol = to
BACnet.
NOTE: If using the OITS panel, in the SETPOINTS/MODE
screen, set the #9 setpoint = to BACnet.
b. Enter the password of “2001.”
c. As needed in the Set/Unit Setpoint menu, change
Source = to Network.
NOTE: If using the OITS panel: as needed in the
SETPOINTS/MODE screen, change the #3 setpoint,
Control Source = to BAS.
3. Re-enable the chiller.
4. Verify that the chiller is operational from the BAS
interface.
Network Setup for all other Chillers
1. Disable the chiller. The chiller should not be operating
while performing this procedure.
2. At the chiller unit controller keypad display:
a. Set the Protocol = to BACnet in the applicable
menu screen.
b. Use Table 3 to determine the operator password
for the specific chiller model.
c. Enter the password.
3. As needed in the Set/Unit Setpoint menu, change
Source = to Network.
3. Re-enable the chiller.
4. Verify that the chiller is operational from the BAS
interface.

NOTE: Chiller models AGZ-A/B, ACZ-A/B, WGZ, and TGZ
have a single unit controller. Models AGS-B/C and
WGS have one unit controller with multiple circuit
controllers. Unit settings for AGS-B/C and WGS
models are adjusted from the unit controller.
Configure PC and Communication
Module
This section explains how to configure your PC and network
settings for use with the communication module’s BACnet
Web Configuration Interface. It begins with a brief explanation
of BACnet networks and IP addressing implications and
an overview of the configuration tool, followed by detailed
instructions for setting up to use the interface. It also
covers how to verify communications and how to reset the
communication module IP Address and Subnet Mask.
Refer to the appropriate MicroTech II Chiller Unit Controller
IOM for instructions on how to use the unit controller
keypad display or OITS menu screens for network setup
( www.DaikinApplied.com ).
Network Considerations
Static IP Address
The BACnet IP Address of the MicroTech II chiller unit
controller consists of the four-octet IP address followed by the
two-octet UDP (User Datagram Protocol) port number. The
BACnet/IP address is a six-octet value analogous to a MAC
(Media Access Control) address. The IP address portion of
the BACnet/IP address must be unique in the BACnet network
segment. The default UDP port number of the unit controller is
47808 (BAC0 in hexadecimal).
