Introduction
This manual describes how to integrate a MicroTech
®
MT2300
SmartSource WSHP unit controller to a BAS (building
automation system) for network communication .
Description
The MicroTech application supports SmartSource
®
Single/
Two Stage and Dual Compressor R32 models with MT2300
controls .
The MicroTech controller supports the BACnet
®
MS/TP
standard protocol . A separate BACnet communication module
must be attached to the unit controller for network integration .
BACnet network parameters include heating/cooling/
dehumidification setpoints, system status, fan and compressor
operation, monitoring, and alarm objects . Once the unit has
been configured as described in the
section, BACnet objects are accessible from the BAS .
It is assumed that the user is familiar with BACnet integration .
Contact the Daikin Applied Controls Customer Support group
at 866-462-7829 or Controls@daikinapplied .com for additional
assistance, if necessary .
Software Version
This document supports the latest version of the MicroTech
application and all subsequent versions until otherwise
indicated . If the MicroTech application software is a later
version, some of the information in this document may not
apply .
The software version can be read from the Application_
Software_Version property of the BACnet Device Object .

BACnet Networks
BACnet is a standard communication protocol for Building
Automation and Control Networks developed by the American
National Standards Institute (ANSI) and American Society
of Heating, Refrigeration and Air-conditioning Engineers
(ASHRAE) specified in ANSI/ASHRAE standard 135-2012
(
) . It addresses all aspects of the various
systems that are applied to building control systems . BACnet
provides the communication infrastructure needed to integrate
products manufactured by different vendors and to integrate
building services that are now independent .
BACnet Network Compatibility
The WSHP unit controller is tested according to the BACnet
Testing Laboratory (BTL) Test Plan . It is designed to meet the
requirements of the most current BACnet Standard as stated
in the Protocol Implementation and Conformance Statement
(PICS) . However, it is not BTL listed . See
BACnet Device Object Types
The MicroTech WSHP unit controller incorporates standard
BACnet object types (i.e., object types defined in the BACnet
Standard) that conform to the BACnet Standard . Each object
has properties that control unit variables . Some object types
occur more than once in the unit controller; each occurrence
or instance has different properties and controls different unit
variables . Each instance is designated with a unique type and
instance index . Some properties can be adjusted (read/write
properties such as temperature setpoints) from the network
and others can only be interrogated (read-only properties such
as status information) .
Device Object Properties
Each BACnet compatible device can only have a single
BACnet Device Object . The Device Object contains other
informative properties as shown in
Table 1 .
