Introduction Document name: D-EIGOC00103-22_02EN_EWATB This document contains information to incorporate a MicroTech® III and Microtech 4 Unit Controllers into a building automation system (BAS) via BACnet® communication protocol. Microtech III and Microtech 4 are suitable for network integration. Data points accessible from a BACnet® network are made available to a BAS provided that the proper communication module (Microtech III and Microtech 4) or the corresponding software option (Microtech 4) are installed / activated. Communication settings and the BACnet® properties with corresponding controller data points are described. BACnet® terms are not defined. Refer to the respective specifications for definitions and details. Product name: EWAT-B Page 3 / 48 Software name: NASH BAS Integration Guide-BACnet protocol 2.

Safety information Document name: D-EIGOC00103-22_02EN_EWATB Only personnel qualified in accordance with IEC (International Electrotechnical Commission) recommendations may be permitted access to electrical components. It is particularly recommended that all sources of electricity to the unit be shut off before any work is begun. Shut off main power supply at the main circuit breaker or isolator. IMPORTANT: This equipment uses and emits electromagnetic signals. Tests have shown that the equipment conforms to all applicable codes with respect to electromagnetic compatibility. RISK OF ELECTROCUTION: Even when the main circuit breaker or isolator is switched off, certain circuits may still be energized, since they may be connected to a separate power source. RISK OF BURNS: Electrical currents cause components to get hot either temporarily or permanently. Handle power cable, electrical cables and conduits, terminal box covers and motor frames with great care. Field of application Intended use Electrical installation Wiring Commissioning and maintenance Faults Storage and transport Disposal Use BACnet communication modules only for control and monitoring functions in ventilation, air conditioning and refrigeration plants. Trouble-free and safe product operation of the above products presupposes transport, storage, mounting, installation, and commissioning as intended as well as careful operation. Fuses, switches, wiring and grounding must comply with local safety regulations for electrical installations. When wiring, strictly separate AC 230 V mains voltage from AC 24 V safety extralow voltage (SELV) to protect against electrical shock! Only qualified staff trained accordingly may prepare for use, commission, and maintain BACnet communication modules. Maintenance of BACnet communication modules generally only means regular cleaning. We recommend removing dust and dirt from system components installed in the control panels during standard service. Only authorized staff may diagnose and correct faults and recommission the plant. This applies to working within the panel as well (e.g. testing or changing fuses). Refer to the environmental conditions specified in the respective data sheets for storage and transport. If in doubt, contact your supplier. Devices contain electrical and electronic components; do not dispose of them in household garbage. Observe all local and applicable laws.

Commission this unit in a BACnet network 4.1 General information Compatibility Unit controller Communicatio n modules BACnet/IP (POL908) The Microtech controllers are tested according to the BACnet Testing Laboratory (BTL) Test Plan. They are designed to meet the requirements of the BACnet Standard as stated in the Protocol Implementation and Conformance Statement (PICS). However, they are not BTL listed. The PICS is located at the end of the present document. Microtech 4 controller can be integrated in an interoperable BACnet network provided one of the followings: a) it is equipped with the proper communication module b) the onboard communication has been made available (software option). Available communication modules to configure Microtech controllers in BACnet network are: 1. BACnet/IP (dedicated network or shared Ethernet LAN) 2. BACnet MS/TP (Master/Slave Token Passing). Both communication modules comply with the standardized profile for BACnet equipment (BAAC BACnet Advanced Application Controller). BACnet MS/TP (POL904) Communicatio n software option BACnet/IP For Microtech 4, BACnet communication is also available 6nboard the controller as a software option. 1. BACnet/IP (dedicated network or shared Ethernet LAN) 2. BACnet MS/TP (Master/Slave Token Passing). Both communication options comply with the standardized profile for BACnet equipment (BAAC BACnet Advanced Application Controller).

Annex 2 EDE files for BACnet Document name: D-EIGOC00103-22_02EN_EWATB Premise EDE file from BACnet IP module (POL908.00) The EDE files are created by the BACnet server each time the server is started. Download and import new files if s any change in controller configuration is done. Some BACnet objects could be no more available or new objects could be added. Also change in BACnet settings affect the new EDE file. EDE files from POL908 module can be exported via ftp as it follows: Step 1 2 3 Action Connect POL908 module to the controller via plug connection. Connect to the POL908 TCP/IP port the bus cable from: · a LAN if DHCP of the module is set to ON · a PC with static IP address if DHCP of the module is set to OFF Set proper IP address and Subnet mask of the module and apply changes. i.e. IP 192.168.1.45 Subnet mask 255.255.255.0 4 Open a resource explorer instance and type the module IP address. i.e. ftp://192.168.1.45/Temp. In the folder "Temp" the EDE files in .csv format are available: EDE file from both modules: BACnet MS/TP (POL904.00) BACnet IP (POL908.00) Step 1 2 3 4 Action Connect POL904/908 module to the controller via plug connection. Connect PC to POL904 by mean of a RS485-USB converter or to POL908 by mean of ethernet cable. A BACnet explorer tool is needed in order to access the module and export the EDE files from it. Freeware tools are available on the internet, i.e. YABE From YABE the EDE export option is available in functions menu.
