Introduction Purpose of this document This document describes Synco’s communication concept on the basis of 8 plant descriptions and specifies for every device the settings required for enabling communication. The document can be used as a tutorial or commissioning tool for combined Synco applications.
Advantages offered by combined applications Systems with interconnected Synco devices enable the individual devices to communicate with each other, offering a number of advantages: Energy savings thanks to demand-based control The most energy-efficient control systems generate heat or refrigeration only when a consumer calls for heat or cooling energy.
The communication concept Communication in the Synco system is based on the KNX standard. This means that the devices communicate in KNX LTE mode (LTE = Logical Tag Extended) with which bus communication can be established – with no need for using a software tool. This mode represents a simple method to build up communication. LTE mode makes use of zone addresses. Process values are exchanged between all devices located in the same zone.
• ACS path: … > Plant > Update device list / Edit device list > Address assignment > Enter device address • RDG settings: P81 = Enter device address With the buttons of the RDG room thermostats and Synco 700 devices, or the RMZ790 / RMZ791 operator units, only the device addresses can be set. To set the area and line addresses, the ACS790 software is required. The RXB / RXL room controllers can be addressed via the ACS790 or via the Handy Tool QAX34.3.
Makeup of plant descriptions The plants contained in this document consist of individual applications a detailed description of which is given on the application sheets. This document only describes the relevant communication settings that ensure optimum communication between the individual devices. The application sheets can be downloaded from Siemens’ HVAC Integrated Tool (HIT) via the internet address given above.

The plant descriptions are examples and can be extended as required, but adherence to the rules of the KNX standard must be ensured. As shown by the following table, it is also possible to use other standard applications in place of the plant sections used here. The respective application sheets can be downloaded from Siemens’ HVAC Integrated Tool (HIT) via the internet address given above.
