6 Introduction This document contains the necessary information you need to incorporate a MicroTech III Water Source Heat Pump (WSHP) unit controller into a building automation system (BAS). It lists all properties, variables, and corresponding MicroTech III WSHP Unit Controller data points. This document supports the network integration parameters available for the Enfinity and Vertical Stack WSHP (single stage compressor) and SmartSource WSHP model types. It also contains two Protocol Implementation Conformance Statements (PICS) for each WSHP model. Unit Controller Data Points The MicroTech III WSHP Unit Controller contains data points or unit variables that are accessible from a MS/TP (Master/Slave Token Passing) network or a network. Not all points are accessible from each interface. This document contains the network details necessary to incorporate the MicroTech III WSHP Unit Controller into the network. Certain data points are available, depending on the model of WSHP unit. The parameters specific to each model are noted in the appropriate locations throughout this document. Protocol Definitions The MicroTech III WSHP Unit Controller can be configured in either an interoperable MS/TP or network. The controller must have the corresponding MicroTech III communication module installed for network integration (see Reference Document section of this document for corresponding literature). Protocol 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 Airconditioning Engineers (ASHRAE) specified in ANSI/ASHRAE standard It addresses all aspects of the various systems that are applied to building control systems. provides the communication infrastructure needed to integrate products manufactured by different vendors and to integrate building services that are now independent. See following section, Configuration, for details regarding the configuration of the communication module into a network. The MicroTech III WSHP Unit Controller is tested according to the Testing Laboratory (BTL) Test Plan. It is designed to meet the requirements of the Standard (ANSI/ASHRAE ) as stated in the Protocol Implementation and Conformance Statement (PICS). However, it is not BTL listed. The PICS are located at the end of this manual. Networks A control network specification for information exchange built upon the use of the LonTalk protocol for transmitting data developed by the Echelon Corporation. LonTalk Protocol A protocol developed and owned by the Echelon Corporation. It describes how information should be transmitted between devices on a control network. LONMARK Certification LONMARK certification is an official acknowledgement by the LONMARK Interoperability Association that a product communicates using the LonTalk protocol and transmits and receives data per a standard LONMARK functional profile. The communication module is in accordance with the LONMARK Heat Pump with Temperature Control functional profile and is LONMARK 3.4 certified. ED

7 Configuration A communication module must be configured before it can be connected to a network. This section describes how to set parameters using the communication module s built-in configuration menu (see Figure 1). The configuration menu is accessed using an application such as Microsoft Windows HyperTerminal. It is assumed that the user is familiar with such an application. Certain parameters are can also be configured via the network (BAS) and are noted as such within the detailed data section for the respective parameter. Parameters Required for Configuration The parameters listed below require configuration in order for the communication module to properly integrate to the network. They must be set using the communication module s configuration menu. Device Instance - must be set to a unique value on the network Device Name - must be set to a unique value on the network MS/TP Baud Rate - must be set according to the network requirements Address Switch - must be set according to the network requirements Accessing the Configuration Menu The communication module s configuration menu is accessed through the DB9 serial connector on the module itself. Any serial terminal device or application (such as Microsoft Windows HyperTerminal) can be used to view the menu and change the configuration parameters. Follow these steps to connect to the configuration menu (see Figure 1): 1. Verify that the terminal application communication settings are set to: bps, 8 data bits, no parity, 1 stop bit, and no flow control. 2. Use a DB9 female-female Modem to Modem (DCE to DCE) serial cross over cable to connect the computer to the communication module. 3. Once connected, press the Enter key to display the following menu: Table 1.

15 Application Mode Input This input network variable coordinates the WSHP with a system controller or other building automation system (BAS). This read/write attribute sets the unit in an application mode (auto, off, heat only, cool only, fan only, or dehumidification). Application Mode does not "force" the unit into any state. However, it disables certain unit operation. For example, an Application Mode of "Cool Only" disables heating, "Heat Only" disables cooling, and "Fan Only" disables heating and cooling.

16 Auxiliary Heat Enable Input While a WSHP normally provides heating by running a compressor to transfer heat from the water loop to the space, some models have a secondary source of heat (i.e. electric heat). This input network variable is used to enable or disable auxiliary heat for models with supplemental electric heat. The default state is Null, in which case auxiliary heat is enabled. Auxiliary heat is typically used during an energy demand situation to save energy. When the entering water temperature is too low and auxiliary heating is the only source of heating, this variable setting is ignored, enabling auxiliary heating.
