s 5 701 Web-Server TM For Synco , Synco TM OZW772... V5.2 living Web server OZW772… allows for remote plant control and monitoring via the web and Smartphone App. Four versions of the web server OZW772... are available: To connect 1, 4, 16, or 250 Synco devices from product ranges Synco 700, room controllers RXB/RXL, RDG/RDF/RDU room thermostats, and the QAX9… Synco living central apartment units. Operate web browser via PC/laptop or Smartphone.
Function "Energy indicator" for monitoring data points for energy-technical limit values, so-called “Green limits", and sending them to 2 e-mail recipients Web services for external applications via Web API (Web Application Programming Interface) Encrypted with https and TLS for e-mails. ACS790 functionality. Use Building Owners/operators End customers, HVAC and electrical installers. Real estate companies, real estate management companies.
Web interface The web server interface is the same using the portal or via a direct connection. The portal has, however, additional functions and available settings. User interface portal Click the symbol to open the web server user interface under a new tab and is then the same as the view under a direct connection. The portal symbol and user name.
Display The display range displays content corresponding to the selected primary and secondary navigation. Plant state The display indicates no fault or the most serious plant fault depending on plant state. Faults Fault sources The web server recognizes failures and fault signals from KNX devices contained in the device list. Own faults also are recognized. Fault display, fault acknowledgement The LED signals a fault on the web server . LED blinks to indicate that a fault is unacknowledged.
Visualize plants Web server OZW772... allows for visualizing technical equipment (HVAC, electrical, energy values) in buildings via plant web pages. For example, a plant web page can be set up visualizing a plant with data points (max. 100 data points per plant web page) on a floor plan. In the event of a fault, users can quickly access the impacted locations. Double-click writable parameters to open a dialog box and edit the value.
Download plant diagrams You can download web-capable plant diagrams from the HIT online platform for standard applications on Synco 700 devices, room controllers RXB/ RXL, and room thermostats RDG/RDF/RDU. Create own plant web pages You can freely design plant web pages. As a hybrid form, you can also modify and extend downloaded plant diagrams. Web page elements Users can also embed additional data in a plant diagram such as energy values V5.
Trend function The trend function is available in web server OZW772… as of V5.0. Any number of data points for connected devices can be logged at a selectable sample rate and queried using the trend function. Data points for devices integrated via KNX S-Mode are also available for the trend function. Trend channels 5 trend channels are available: Each trend channel can include up to 100 data points. The trend channel can be labelled using a plain text name.

Web services The "Web Application Programming Interface" (Web API) is an interface to provide web services client to the web server. All web API functions are started via "http" or encrypted with "https". Each session stars with authentication at the web server. If "Home Control App" is installed on a smartphone, the app accesses, using the web services, via web API, data points for devices on the KNX network (Communication connection for smartphone, see page 12).
Equipment combinations The following Synco devices can be connected to the web server OZW772.
