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. 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 message
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.
Common fault
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.
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.
History
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.
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).
Updates
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. Firmware 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. Procedures are communicated when a firmware update is issued.

The web server uses the "Energy indicator" function to read selected data point
values from the bus devices and to compare the values to energy-related limit values, or so-called "Green limits".
The data points are also monitored for adherence to the "Green limits".
As a result, the "Energy indicator" is displayed in the form of a tree leaf.
Note
The "Green limits" are used only together with the "Energy indicator" function. They
do not represent process or safety limit values which trigger e.g. fault messages or
turn off the plant in the event of limit violations.
Web server, e-mail
The "Energy indicator" can send its information periodically (adjustable via web
server) to a maximum of 2 e-mail recipients.
Tree leaf as
"Energy indicator"
Green leaf
"Green leaf"  Green tree leaf, leaf pointing up.
Orange leaf
"Orange leaf"  Orange tree leaf, leaf pointing down.
 The "Green leaf" symbol indicates that a data point value has not exceeded
its "Green limit", i.e. the value is within a "green" range in terms of
energy consumption.
 The "Orange leaf" symbol indicates that a data point value has exceeded its
"Green limit", i.e. the value is outside a "green" range in terms of energy consumption.
Standard EN 15232
The "Energy indicator" function is based on standard EN 15232 "Energy efficiency
in buildings".
Example: "Energy indicator" web page function
