Synco living Overview Synco living products Central apartment unit The QAX9.. central apartment unit is the heart and brain of the system. From the central unit, all functions can be conveniently controlled and checked on the display. Room unit The room unit acquires the room temperature and enables the user to individually change settings predefined by the central apartment unit (setpoints or operating mode). Comfort mode can be extended at the touch of a button.
Central apartment units QAX9.. Introduction Overview Synco living is a Home Automation System which can be easily matched to changing conditions in living spaces. The heart and brain of the system is the central apartment unit. It offers intelligent room comfort because it ensures optimum control of room temperature, indoor air quality, light conditions (combined control of lighting and blinds), a high level of security and acquires energy consumption in apartments with up to 12 rooms.
Consumption data acquisition When integrating the WRI982 consumption data interface, Synco living becomes an ECA (Energy Cost Allocation) system. Meters The meters always store the current consumption data (legal requirement). Consumption data interface WRI982 The WRI982 consumption data interface queries the meter readings (at 4-hour intervals) and the monthly and set day values (once a day) and transmits them wirelessly to the central apartment unit.

Web servers OZW772 The OZW772.. web servers (see Data Sheet N5701) allow remote control and monitoring of plants via the web and smartphone apps. A total of 4 types of web servers are available, allowing the connection of 1, 4, 16 or 250 Synco 700 devices, RXB/RXL room controllers, RDG/RDF/RDU room thermostats or Synco living QAX central apartment units.
User interface Primary navigation Primary navigation provides the following functions: Home Energy indicator Faults File transfer User accounts Device web pages Menu-based plant and device operation. Display and operate "Energy indicator" data points. Display system faults. Download consumption data and event history, upload documents, logos and system definitions. User administration. Create device list and operating pages.
Visualization of plant The OZW772 web server enables building plants to be visualized via plant web pages (below: central air handling unit) and setting values in dialog boxes to be changed (below: preselection of operating mode). Creating plant web pages For convenient creation of plant web pages – also called plant diagrams – an action bar appears. Web-compatible plant diagrams can be freely created. Or plant diagrams available via HIT can be modified (see page 87).
Function "Energy indicator" The "Energy indicator" function is used by the OZW772 web server to read predefined data point values from the devices on the KNX bus and to compare them with energy-related so-called "green limits". This means that the data points are monitored to ensure their "green limits" are observed. The result is presented by the "Energy indicator" in the form of a leaf. Note: The "green limits" are only used in connection with the "Energy indicator" function.
Network environment of web server OZW772 Commissioning The web server is commissioned on site via the USB interface using a PC/laptop on which a suitable web browser or the ACS790 software is installed. It is to be checked whether the OZW772 web server is integrated in a private network (LAN) or a proprietary network (Intranet) with/without connection to the Internet. Another criterion is whether the web server shall send e-mails to an in-house mail server or via the Internet to an external mail server.

Product list When clicking on field devices (sensors, valves, etc.), the devices are highlighted on the product list so that their data are instantly displayed (see valve Y3 in the illustrations).
Service and operating software ACS790 The ACS790 service and operating software (see Data Sheet N5649) is to be installed on a PC/laptop.
Popcard A standard popcard with a predefined tree structure and contents of the operating pages is available for each device type. Every selected operating page is automatically updated, meaning that the color of the circle symbol changes from red (not updated) to black (updated). User-defined popcards are created by the administrator. This provides for quick access to frequently used data points in the user views "Operation" and "Maintenance".
Engineering of plant Application "Plant engineering" enables the data points (parameter sets) of the devices to be edited.
Service tool OCI700.1 The OCI700.1 service tool (see Data Sheet N5655) consists of a service case containing a CD-ROM with the ACS790 software, the OCI700 service interface and 3 device-specific connecting cables. Software and service interface facilitate commissioning and servicing of Synco devices and communication via KNX. The OCI700.1 tool is for installation on a PC/laptop.
Synco and KNX KNX www.knx.org is based on the European Installation Bus (EIB).
KNX network A fully extended KNX network has a 3-level structure. Area line 0 forms the network’s backbone. From each area line, 15 main lines (area 1…15) branch off via area couplers (Ac), and from each main line 15 lines (lines 1…15) branch off via line couplers (Lc). Area 15 Ac 15.0.0 ea e 2 Lc 15.3.0 1 1 Line 3 1 Line 2 ( ne Line1 0 bo Lc 15.2.0 2 2 3 3 3 64 64 64 Area 3 Ac 3.0.0 Main line 3 2 3 2 3 2 Lc 1.2.0 1 2 3 1 64 64 1 2 64 Area 1 2 Main line 1 3 Lc 1.3.
IP router Technically speaking, the IP1) router is not identical with the area/line couplers. Instead of having a connection within KNX, a "KNX - IP network" connection is established. In that case, an IP router connects a KNX area or KNX line to an IP network. 1) IP = Internet Protocol: Network protocol for data traffic, routing and with internetworking for global addressing. Siemens IP router 5WG1 146-1AB02, short product no. N146/02. Bus connection via terminals, IP network connection via RJ45.
Example KNX network coupled with IP network via IP router (area line 0) LTE filter table: 1) Normal (route), 2) Route all Alarm drains Alarm drains – in the above example, the OZW772 web server and the RMZ792 bus operator unit – must receive all alarm signals and all other data from the network and, for this reason, must be installed on a superposed line. Main line 2 acts as a "backbone" and the alarm drains need be installed on that line. Area coupler Ac 2.0.0 must be set to "Route all telegrams".
Engineering tool software, ETS Professional LTE mode data points Communication between Synco devices takes place in LTE mode via LTE data points. S-mode data points Communication between Synco devices and third-party KNX devices is executed in S-mode via S-mode data points. In the Synco devices, the S-mode data points correspond to a subset of the LTE data points.
Simple, versatile and reliable Comprehensive product range From basic temperature control to complete HVAC plant control – from heat or refrigeration generation control through distribution to individual room control: Synco offers a comprehensive range of standard controllers for all types of applications. Versatile and expandable for future use Synco supports the entire life cycle of a building.
