Description

Application

The MicroTech III® BACnet Communication Module incorporates a MicroTech III Chiller Unit Controller into a BACnet local area network (LAN). It supports the BACnet MS/TP (EIA 485) data link layer (physical layer.)

The BACnet Communication Module is a printed circuit board with a plastic enclosure that connects to the left side of the D-Net™ Module as shown in Figure 1 or directly to the MicroTech III Chiller Unit Controller. The BACnet Communication Module provides access to the MicroTech III Chiller Unit Controller variables and parameters via BACnet.

Note: The D-Net module is an optional feature that provides remote monitoring and diagnostic

capability for certain models of Daikin McQuay chillers. Please refer to supporting literature, available on www.daikinmcquay.com, for additional details about D-Net.

The BACnet Communication Module connects the MicroTech III Chiller Unit Controller to a building automation system (BAS) on a BACnet local area network. It is the interface for the exchange of BACnet objects between the network and the unit controller. Refer to the MicroTech III Chiller Operation Manual, available on www.daikinmcquay.com, for keypad details.

Component Data

Figure 1 shows the BACnet Communication Module, located on the far left-hand side of the image below. It is connected to the D-Net Module, which is mounted directly to the unit controller. Figure 2 shows the important features of the BACnet Communication Module.
