Building Technologies 2014-10-15
The display range displays content corresponding to the selected primary and sec-
ondary navigation.
The display indicates no fault or the most serious plant fault
depending on plant state.
The web server recognizes failures and fault signals from KNX devices contained
in the device list. Own faults also are recognized.
The LED signals a fault on the web server . LED blinks to indicate that a fault is
unacknowledged. The LED continues to be lit for as long as the fault is pending
after the fault is acknowledged with the button via web operation or ACS. (See
page 10 for LED displays and operating buttons).
Fault status messages can be sent as an e-mail to as many as 4 e-mail recipients
and/or via a service provider to SMS recipients. You can set the fault priority for
each e-mail recipient (urgent/all). Each receiver has a "Time switch with calendar"
to program three sending times per day and holidays/special days.
On the Climatix IC/Synco IC Internet portal, faults are logged as common faults.
The portal sends alarm notifications to the defined e-mail addresses in the event of
a common fault.
The web server generates system reports and periodically sends the system oper-
ating 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).
Press the button on the web server to send a system report to all defined e-mail
recipients regardless of fault priority.
The last 500 fault events, fault messages and system reports are entered in the
web server's circular message buffer. The event or history data can be read via
web browser.
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).
We differentiate between the following:
 System definition updates to integrate device descriptions of new devices in the
web server.
 Firmware updates to update the web server to the latest firmware version. Firm-
ware updates may also contain new device descriptions (system definitions).
A system definition update requires one simple action via the web browser.
No operator actions on the web server are required to update the firmware. Proce-
dures are communicated when a firmware update is issued.
The web server is compatible with the service and operating software ACS790
V8.00 and higher.
No ACS790 functionality is available when accessing via the portal.
