System report System messages The web server generates system reports and periodically sends the system operating state to e-mail recipients. Messages are sent as per the set time (hh:mm), message cycle interval (1...255 days), and priority (urgent/non-urgent). Connection test Press the button on the web server to send a system report to all defined e-mail recipients regardless of fault priority.
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 (version 5.
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).
