Integration; Configuring The Bacnet Communication Module - McQuay MicroTech III Installation And Maintenance Manual

Integration

Once the BACnet Communication Module has been properly installed on the MicroTech III Chiller
Unit Controller, it is then necessary to configure the unit controller for integration into a Building
Automation System (BAS) via the BACnet IP network. The configuration process is described in
the following section.

Configuring the BACnet Communication Module

The BACnet Communication Module is configured using the keypad/display on unit controller.
Table 1 describes all of the available BACnet IP network parameters used to establish
communication between the unit controller and the BAS. The items shown in boldface are required
for minimum network configuration. Table 1 also defines the factory defaults (as indicated by the
Initial Value/Note column) for each network parameter.
Refer to the MicroTech III Chiller Unit Controller Operation Manual for additional information on
using keypad/display to set unit parameters and factory defaults for unit setpoints. Refer to McQuay
Protocol Document ED 15120 for descriptions of the available BACnet objects.
BACnet IP Configuration using the Keypad/Display
1. If you have not already entered a password, select Enter Password from the Main Menu screen
2. Enter Password: 5321 and then press Enter.
3. Scroll down to View/Set Unit (i.e. turn the knob clockwise) and press Enter.
4. Scroll down to BACnet IP Setup and press Enter.
Note:
5. If the BACnet IP network does not require DHCP (Dynamic Host Configuration) to be enabled,
6. If your BACnet IP network requires static IP Addressing for non-DHCP networks, follow steps
IM 966-1
(i.e. turn the circular knob on the unit controller until the cursor is in the proper location) and
press Enter (i.e. press down on the knob). See Figure 6.
a. If you are not at the Main Menu and need to enter a password, press the Back button from
any other menu screen until you reach the Main Menu and follow step 1. See Figure 6 for
the location of the Back button.
b. If you have already entered a password, skip to step 3. See Figure 6 if you are not certain
whether or not a password has been entered.
The BACnet IP Setup menu only appears if a BACnet Communication Module is installed
correctly (see Installation section of this document for details.) If the BACnet
Communication Module is installed correctly and this menu still does not appear, cycle
power to the unit controller and repeat the procedure.
go to step 6. If your BACnet IP network does require DHCP to be enabled, confirm DHCP is
set to On and skip to step 8. See Table 1 for additional details about DHCP configuration.
a-b below:
a. Set DHCP to Off by following the two steps below:
i. From the BACnet IP Setup menu, turn the knob clockwise until DHCP is highlighted
and then press Enter;
ii. Turn the knob counter-clockwise until DHCP = Off and then press Enter.
b. Modify the Given IP Address (Gvn IP), Given IP Mask (Gvn Msk), or Given IP Gateway
(Gvn Gwy) as directed by the system integrator. Follow steps i-iii below:
i. Fully change the three digits in each of the four octets of the desired field (for example,
172.016.001.123 for Gyn IP or 255.255.000.000 for Gyn Msk.) If all three digits of all
four octets are entered, skip to step 8 after entering the last digit. If all three digits are
not entered (ie, 172.16.1.123 or 255.255.0.0) then continue with steps ii and iii below.
