5.2.3 Operation and monitoring with OZW772
.
The OZW772 web server enables users to operate a Synco HVAC system from
a remote location – via PC or from a smartphone via the web. A start page
shows the most important data points. A combination of menu/path navigation
enables users to access all data points quickly and straightforwardly. The entire
installation can be visualized in the form of plant diagrams. Alarm and state
messages can be forwarded to different message receivers, such as e-mail,
SMS, etc.
For details, refer to Commissioning Instructions CE1C5701.
