Daikin MicroTech III Sales And Engineering Data Sheet

ED 15103-6 • MICROTECH III WSHP UNIT CONTROLLER 4 www.DaikinApplied.com
InTroduCTIon
Overview
This purpose of this document is to serve as an integration
guide for the MicroTech
®
III Water Source Heat Pump (WSHP)
Unit Controller from Daikin Applied. It provides the necessary
information to incorporate the WSHP unit controller into
a building automation system (BAS). It lists all BACnet
®
properties, LonWorks
®
variables, corresponding WSHP unit
controller data points and conguration instructions.
How to use this Guide
Refer to the rst section for a glossary for common terms and
protocol denitions.
Use the primary portion of this protocol document, the
BACnet and LonWorks summary tables, for point mapping
and addressing details. Some parameters require further
explanation or information beyond what is shown in the tables.
Those affected parameters are noted within each table, along
with the reference to where the additional details can be found.
See BACnet Conguration and Commissioning and
LonWorks Device Management for instructions on how to use
conguration and system commissioning and verication tools
for BACnet and LonWorks variables.
Effective Occupancy Modes includes two tables for both
BACnet and LonWorks Effective Occupancy modes. This is
helpful for determining the interaction among the various inputs
that ultimately determine the effective occupancy mode of the
unit.
The Space Temperature Setpoint Methods section provides the
temperature setpoint operation details and diagram.
Terminology
Unit Controller Data Points
The WSHP unit controller contains data points or unit variables
that are accessible from a BACnet MS/TP (Master Slave/Token
Passing) network or a LonWorks network. Not all points are
accessible from each interface. This document contains the
network details necessary to incorporate the unit controller into
the network.
BACnet Networks
BACnet Protocol
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) specied in ANSI/ASHRAE standard 135-2004
(www.ashrae.org). 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 BACnet Standard as stated in the
Protocol Implementation and Conformance Statement (PICS).
However, it is not BTL listed. The PICS are found in Appendix
A: Protocol Implementation Conformance Statements (PICS)
with separate documents for Ennity Single Stage Compressor,
SmartSource Single and Two Stage Compressor, and Ennity
Large Two Compressor WSHPs.
BACnet Objects
The WSHP unit controller incorporates standard BACnet object
types (i.e., object types dened in the BACnet Standard) that
conform to the BACnet Standard. Each object has properties
that control unit variables or data points. Some object types
occur more than once in the unit controller; each occurrence
or instance has different properties and controls different
unit variables or data points. Each instance is designated
with a unique type and instance index. Some properties
can be adjusted (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 detailed table that gives the Object Identier,
Property Identier, and other information.
lonWorks Networks
A control network specication for information exchange built
upon the use of LonTalk
®
for transmitting data developed by
the Echelon Corporation.
LonTalk Protocol
A protocol developed and owned by the Echelon Corporation.
It describes how information is transmitted between devices on
a control network.
LonMark Certication
LonMark certication is an ofcial acknowledgement by
the LonMark Interoperability Association that a product
communicates using the LonTalk protocol and transmits and
receives data per a standard LonMark functional prole. The
LonWorks communication module is in accordance with
the LonMark Heat Pump with Temperature Control functional
prole and is LonMark 3.4 certied. Refer to www.lonmark.org
for certication conformance information.
