1. Introduction
This document contains information to incorporate a MicroTech® III and Microtech 4 Unit Controllers into a building automation system (BAS) via Modbus communication protocols.
Microtech III and Microtech 4 are suitable for network integration. Data points accessible from a Modbus 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 / acrivated.
Modbus terms are not defined. Refer to the standard Modbus specifications for definitions and details about the protocol.

3. Safety information
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 | Use Modbus communication module only for control and monitoring functions in ventilation, air conditioning and refrigeration plants. | |
| Intended use | Trouble-free and safe product operation of the above products presupposes transport, storage, mounting, installation, and commissioning as intended as well as careful operation. | |
| Electrical installation | Fuses, switches, wiring and grounding must comply with local safety regulations for electrical installations. | |
| Wiring | When wiring, strictly separate AC 230 V mains voltage from AC 24 V safety extralow voltage (SELV) to protect against electrical shock! | |
| Commissioning and maintenance | Only qualified staff trained accordingly may prepare for use, commission, and maintain Modbus communication modules.Maintenance of Modbus communication modules generally only means regular cleaning. We recommend removing dust and dirt from system components installed in the control panels during standard service. | |
| Faults | 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). | |
| Storage and transport | Refer to the environmental conditions specified in the respective data sheets for storage and transport. If in doubt, contact your supplier. | |
| Disposal | Devices contain electrical and electronic components; do not dispose of them in household garbage. Observe all local and applicable laws. |
4. Commission this unit in a Modbus network

5.1 Alarm Codes and Indexes
| Premise | Unit communicates to BAS the status alarm through Codes and Indexes.Those are grouped in 3 level of alarm | ||
| Levels of Alarm | The three levels of alarms are as it follows: | ||
| Level | Description | ||
| Warning | They are notifications from unit or equipment of an incorrect status | ||
| Problem | They are notifications from unit or equipment of a status that does allow unit to work properly | ||
| Fault | They are notifications from unit or equipment (circuits, Compressors, Sensors, etc) that can cause stop of the unit or specific equipment | ||
| Index | Index describes the general cause of the notification | ||
| Code | Code describes which equipment or device of the unit is generating a notification | ||
| CODE | INDEX | LEVEL | Device | Description |
| 257 | 1 | Warning | Unit | Condenser Entering Water Temperature Sensor Failure |
