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 to open the web server user interface under a new tab and is Click the symbol then the same as the view under a direct connection. The portal symbol and user name.
Primary navigation Primary navigation offers the following functions: Home Energy indicator Faults File transfer User accounts Device web pages Menu-based plant and device operation. Display and operating of "Energy indicator" data points (Displayed only if a controller is connected with an Energy indicator) Display system faults. Create and manage trend functions Download consumption data and message history, upload documents, logos, and system definitions as well as firmware update User administration.
Time The web server has a system clock with adjustable time zone and daylight saving/ standard time changeover. As clock time master, it can send the set system time (date and time) to KNX devices (clock time slave). For the system clock, the NTP network time server can perform the time synchronization and, if used as a time clock master, forward the data to all KNX devices (time clock slaves).
Example Plant web pages for heating plant Example Plant web pages for HVAC and lighting, blinds 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.
KNX S-Mode Integration of KNX S-Mode data points permits central control of heating, ventilation, air conditioning, and electrical installations. Data points recording by OZW can be used, for example, for trending, to depict the plant diagram or reused for thermal or electrical energy consumption. Number of S-Mode data points Version OZW772.01 supports 7 standard data points for system time and alarm info functions. For version OZW772.
Trend function The trend function can be defined directly in the web server OZW772… as of version 5.0. 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 labeled using a plain text name.
Trend graph The data for a trend channel can be graphically displayed on the web user interface. The function is available for OZW772… as of version 6.0. Data transmission per e-mail Up to 2 e-mail recipients can be defined for the trend data. Each trend channel can send its data to one or both e-mail recipients. The send interval can be set individually for each trend. Import/Export Trend definitions can be imported to the web server or exported from the web server.
Consumption data trending The "consumption trend" function is available in web server OZW772… as of version 3.0. The following devices are supported: • Synco 700: RMU7x0B, RMH760B, RMK770 (as of version 2.0), RMS705, RMS705B, RMB795, RMB795B • Synco living: Central apartment unit QAX903, QAX913 OZW772... as of version 5.0 Energy and volume meters that use KNX data points are supported with the integration of KNX S-Mode as of web server version 5.0.
Function "Energy indicator" The "Energy indicator" function is available in web server OZW772… as of version 4.0. The following devices are supported: • Synco 700: RMS705B, RMU7x0B, RMH760B, RMK770 (as of version 2.0), RMB795B Central apartment unit QAX903, QAX913, QAX910 (as of version 3.
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 starts with authentication at the web server. If "Home Control IC” 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 14).
Equipment combinations The following Synco devices can be connected to the web server OZW772... Synco range Synco devices Universal controllers Heating controllers Boiler sequence controllers Central control units Switching & monitoring units Bus operator unit Room unit Central communication unit RMU7x0, RMU7x0B RMH760, RMH760B RMK770, RMK770 V2 RMB795, RMB795B RMS705, RMS705B RMZ792 QAW740 OZW771, OZW775 Data sheet no.
