Page 5: Introduction
Introduction This document contains the necessary information you need to incorporate a Daikin McQuay ® Magnitude™ Chiller Unit Controller into a building automation system (BAS). It lists all BACnet ® properties, L variables, and corresponding Magnitude Chiller Unit Controller data points. It ORKS also contains the BACnet Protocol Implementation Conformance Statement (PICS).
Page 6: Basic Protocol Information
Some object types occur more than once in the Magnitude Chiller Unit Controller; each occurrence or instance has different properties and controls different unit variables or data points. Each instance is designated with a unique instance index. Some properties can be adjusted ED 15117...
Page 7 (read/write properties, e.g., setpoints) from the network and others can only be interrogated (read-only properties, e.g., status information). Each data point accessible from a BACnet network is described with a table that gives the Object Identifier, Property Identifier, Full BACnet Reference or path, and the Name enumeration of the property.

Page 9 communication module as soon as the change is received. The allowable range of characters for the device object name will be 1 to 31 characters. If an empty string is read from the controller, the following default name will be used: Default device object name: MTE Chiller UCA - address* *Address = the MAC Address For example:...
Page 10 While the Magnitude Chiller Unit Controller supports all shown object types, not all object types are used. See the Object List for details. The device properties will be read-only. The controller values are writable from BACnet via the BACnet TimeSynchronization services. ED 15117...
Page 11: Network Considerations
Network Considerations Access to Properties Object properties are accessible from the network by specifying the device object identifier, object identifier, and the property identifier. To access a property, you must specify the object identifier including the device object identifier or the object name including the device object name and the property identifier.
Page 12 BBMD address. If the new value is non-zero, a Register-Foreign-Device message is sent to the BBMD address. Changing the BBMD address may affect the operation of other BACnet devices on the network. This parameter can only be accessed and configured via the unit controller OITS panel. ED 15117...
Page 13: Bac Net D Evice M Anagement
Foreign Device Time-To-Live The Foreign Device Time-To-Live (FDTTL) value is read from the Magnitude Chiller Unit Controller during the BACnet communication module’s initialization phase. The BACnet communication module continues to poll the FDTTL parameter during run-time. If the FDTTL is changed at the unit controller during run-time, the update is automatically applied to the BACnet communication module as soon as the change is received.

Page 15: Bac Net Device Management Configuring The Unit Controller
Configuring the Unit Controller The Magnitude Chiller Unit Controller can operate with the default values of the various parameters. However, certain communication parameters must be configured appropriately (see the appropriate Magnitude Communication Module Installation Manual for details). Default values may be changed using the unit controller OITS panel or via the BACnet network (see the Magnitude Chiller Unit Controller Operation &...

Page 19 External Interface File (XIF) guidelines specify exact documentation rules so that proprietary configuration tools are not required to commission and configure L devices. The L Chiller Communication ORKS ORKS Module is self-documenting so that any network management tool can obtain all the information needed over the network to connect it into the system and to configure and manage it.
Page 20: Typical Application: Minimum Integration
See Protocol Point Summary section (Tables 4-7) for a complete list of all L ORKS variables or BACnet points available to the network. For a detailed description of all available data points, see the Detailed Data Point Information section. ED 15117...
Page 21: Alarms
Alarms Alarms in a Magnitude Chiller Unit Controller are divided into three classes: Faults, Problems, and Warnings.  Fault Alarms have the highest priority.  Problem Alarms have medium priority.  Warning Alarms have the lowest priority. Notification BACnet Magnitude Chiller Unit Controllers may have their alarms monitored by one of two methods: 1) a BACnet Binary Output indicating whether any alarms exist, or 2) Alarm value using three BACnet Analog Value objects.
