Functions
Basic functions Basic functions of the central communication unit OZW775:
• Monitor KNX network member devices and acquire fault statuses in HVAC plants via
digital and universal inputs.
• Signal faults via direct connection to local operator station and/or via modem to
operator stations, SMS recipients, pagers, fax machines, email recipients.
• Central communication unit V2.0 with web server: Send faults to web browser via
Ethernet and/or direct connection or modem.
• Operate HVAC plants and equipment with operator stations and/or web browser, and
display process values on operator stations and/or web browser.
• Function "Clock time master" for default system time (date and time) to KNX network
member devices.
• Function "System clock" with adjustable time zone and daylight saving/standard time
changeover.
Faults
Fault sources
• "System" fault source
The central communication unit detects device failures and faults on the KNX
network listed in the unit’s device list.
• "Local" fault source
The central communication unit identifies internal faults and fault states at the digital
and universal inputs configured as fault inputs (fault source "Local"). Typical faults at
digital and universal inputs:
− Overload signals from thermal cutouts.
− Error states signaled by switches or monitors.
− Limit value violations.
− Fault states of aggregates and plants.
− Common messages from external plants.
Fault indication Depending on the fault's source, the central communication unit indicates faults either
via "Local" or "System" LED. The "Local" LED also indicates state "Hours run for
service reached".
Fault relays
You can configure two relay outputs as fault relays. As a result, faults can be indicated
by optical or acoustic alarm equipment in addition to LEDs.
Fault status message
Faults can also be sent as text messages via PC or modem interface. For messages
via modem, both the number of repetitions and the modem message interval can be
parameterized.

Fault acknowledgement
A
The "Local" LED blinks to indicate that a fault is unacknowledged. The LED continues
to be lit until the fault is no longer pending even after the fault is acknowledged with the
"Ack" button. "Ack" resets the fault relay if a fault relay is configured.
The same applies to unacknowledged "System" faults in the event of a configured fault
relay. Without fault relay, a "System" fault is acknowledged automatically, i.e. the
"System" LED is lit immediately (no blinking until acknowledged).
External fault acknowledgement is possible via digital input, provided the input is
connected to input "Ack" on function block "Faults".
System report The central communication unit can generate system reports and periodically send the
system operating state to different types of message receivers.
History The history includes the last 500 events on faults, fault messages, and system reports.
The events are entered in the circular message buffer of the central communication
unit. The history data can be read via web browser and the ACS software.
Offline trend "Offline trend" allows logging values for selected data points of the central
communication unit and for Synco devices listed in the device list. The ACS7 software
is necessary to define trends and trend displays on an operator station as well as to
specify data exports (e.g. to Excel).
5 offline trends can be defined and run at the same time. One trend may contain 10,000
values (number of data points x number of samplings).
Central communication unit memory to log for each trend: Examples
• 1 data point at 30 second intervals for 83 hours.
• 6 data points at 30 second intervals for 27 hours.
• 10 data points at 5 minute intervals for 7 days.
The number of values that can be logged is reduced if text information (e.g. input
names, aggregate names for runtime totalization) is also recorded.

Mechanical design
Basic design
The central communication unit consists of the housing lower section with printed circuit
boards and connection terminals. The upper housing section contains the printed circuit
boards. The LEDs, operating buttons, interfaces, and slots for the CF cards (compact
flash memory cards) are integrated in the upper housing section. These elements and
the connection terminals are labeled on the front of the housing. The shape and dimensions of the housing sections conform to DIN 43880 (size 2).

Inputs and outputs
Digital inputs
Universal inputs
Relay outputs
The central communication unit contains various function blocks (FB). The functionality
of the unit can be extended by connecting (binding) the digital inputs N.D1…N.D8 and
the universal inputs N.X1…N.X8 to the FB inputs "d", "x", and "i" (see figure and
function block description).
The digital inputs N.D1…N.D8 help connect potential-free status contacts. They act as
fault inputs when connecting digital inputs to FB "Faults". When connected to FB
"Operating hours", the number of operating hours of aggregates (burners, pumps, fans,
etc.), can be counted.
The universal inputs N.X1…N.X8 can be configured for potential-free status and
counting impulse contacts and analog signals from sensors and transmitters.
Universal inputs configured for status contacts (digital) or limit values (analog) and
connected to FB "Faults" act as fault inputs.
When universal inputs are configured for operating status contacts of aggregates and
connected to FB "Operating hours", the operating hours can be acquired.
When universal inputs are configured for counting pulses and connected to FB
"Meters", consumption values (heat, gas, electricity, etc.) can be acquired.
The outputs of relays N.Q1…N.Q4 have NC contacts, those of relays N.Q7, N.Q8 have
NO contacts. To signal faults (e.g. with signal lamps, horns), relay 1 and/or relay 2 of
FB "Faults" are connected to one of the relays N.Q_.
If one of the relays N.Q_ is connected to an FB "7-day time switch with control switch",
relay N.Q_ in "Auto" position operates as per the time switch program, else per the
control switch position "Off" or "On".
