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.

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".

Function blocks
FB "Faults"
FB "Operating hours"
FB "Meters"
FB "7-day time switch
with operation selector"
FB "System report"
FB "Message receivers"
FB "Faults" is designed for 20 fault inputs. Inputs N.D1…N.D8 (digital) and N.X1…N.X8
(digital/analog) are connected to FB inputs "x". "Relay 1" and/or "Relay 2" is activated
depending on fault priority and source.
FB "Faults" handles faults and failures of the Synco devices (“System“ faults) listed in
the device list as well as faults at the fault inputs and faults of the central
communication unit ("Local" faults)..
To facilitate external fault acknowledgement, a digital input must be connected to input
"Ack". External fault acknowledgement acts like pressing the "Ack" button.
FB "Operating hours" can handle up to 5 runtime totalizers. The operational status
contacts of the aggregates are connected to FB inputs "d" via the digital inputs
N.D1...N.D8 or N.X1...N.X8 (configured as digital inputs).
If a service interval is defined, the “Local“ LED indicates when the number of operating
hours is reached and, if configured, a service alarm is issued.
FB "Meters" can handle up to 8 counting values. The universal inputs N.X1…N.X8
(configured as counting pulses) are connected to the FB inputs "i". The acquired
counting pulses from heat, water, gas, electricity meters are converted to consumption
values, e.g. energy in Wh, kWh or volume in m
3
. The 15 monthly values along with
readout dates are stored.
The 4 FB "7-day time switch with control switch" allow for switching various consumers
in dependence of time via the relays N.Q_. Each 7-day time switch allows for programming up to 6 switching points (3 "On", 3 "Off". Additionally, a configurable operation
selector with positions "Auto" / "Off" / "On" is integrated.
If a time switch output "Q" is connected to a relay input, position "Auto" ensures that the
relay is energized and deenergized as per the time program, or the relay is constantly
deenergized or energized.
In FB "System report", the time the message is sent (hh:mm) and the message cycle
interval (1...255 days) for sending system reports can be programmed. A system report
is sent to one or several message receivers depending on fault priority (urgent/not
urgent).
FB "Message receivers" is subdivided into 4 receivers. Message suppression via input
"d" acts on all receivers. You can set both receiver type and fault priority individually for
each receiver. Each receiver has a "Time switch with calendar" to program three
sending times per day and holidays/special days.
Example: All fault messages from Monday through Friday 08:00 - 18:00 are sent to
receiver "Service business receiver", e.g. to a fax machine. Outside these hours, the
fault status messages are sent to receiver "24-hour service", e.g. SMS to mobile phone.
The outputs "c" of FB "Message receivers" are connected to inputs "c" of the PC USB,
modem, or Ethernet interfaces. The PC USB interface is designed for local commissioning, operation and monitoring (alarming).
Remote operation and monitoring are possible via modem (dial-up) and, at the same
time, via Ethernet (Internet/intranet) to one (or several) web browsers.

Interfaces The central communication unit has three interfaces to communicate between unit and
user, and the interface or connection for the KNX bus.
PC
The "PC" interface is intended to directly connect a central communication unit to a
local operator station. A USB cable, type A-B, is required to this end.
Modem
The "Modem" interface is intended to connect a modem via RS-232. When communicating via modem, the following message recipients are supported: Operator stations
(PC/laptop with ACS software), SMS recipients, pagers, fax machines.
Ethernet
The interface labeled "Ethernet" corresponds to a RJ45 plug on the Ethernet card
OZZ7E5. Order the card separately and insert in the central communication unit. A
network cable Cat-5 is required to connect to the Ethernet (Ethernet category 5 cable).
KNX
The"KNX" labeled connection terminals CE+ and CE- are intended for the KNX bus.
For more information on the KNX bus, see data sheet N3127.
Parallel operation
We speak of parallel operation if one central communication unit is operated with two or
multiple operator stations. Also, e.g. with one operator station via USB, and/or via
modem, and/or via Ethernet.
Operation
Communication connections for local operation (USB), and for remote operation via
modem and Ethernet.

Mounting notes
Installation notes
You must mount the central communication unit in a cabinet or control panel. Make
sure service can easily access the unit.
• Standard mounting On standard rail TH 35-7.5
• Screwed-on mounting Screwed to rear wall
• Mounting position Horizontal only
• Mounting and dimensions See "Dimensions"
Important notes
Observe the following important notes for mounting and installation:
• The central communication unit must
be mounted in a cabinet or control panel,
as when mounted on a freely accessible wall, the relay output terminals
carrying mains voltage (bottom of the unit, terminals not covered) are not
protected against electric shock hazard.
• Run fuses, switches, wiring and earthing as per local regulations for electrical
installations.
• The relay contacts of the central communication unit can switch either mains
voltage or
low-voltage. Applying both mains and low voltage is not permitted.
• You must connect circuits with relay contacts Q11, Q12 through Q41, 42 to the
same mains phase.
• You must connect circuits with relay contacts Q73, Q74 and Q83, Q84 to the
same mains phase.
• Connect only potential-free contacts to digital inputs D1…D8 and universal
inputs X1…X8 (configured for digital inputs signals).
• We do not recommend plant monitoring via PC interface in environments with
strong electromagnetic interference (e.g. in industrial environments with
electrical welding equipment).
Operating voltage The central communication unit operates on AC 24 V and must meet requirements for
SELV/ PELV (safety extra low-voltage / protective extra low-voltage).
Use only safety isolating transformers suited for 100 % duty (as per
EN 61558-2-6).
Wiring Plan sufficient space around the unit for easy wiring. The unit’s terminals are arranged
to eliminate cross-wiring of input and output lines to prevent faulty wiring to the greatest
extent possible.
The terminals for digital inputs, universal inputs, and the KNX bus are located at the top
of the unit (low-voltage side). The terminals for AC 24 V operating voltage and relay
outputs carrying mains voltage are located at the bottom (mains voltage side).
Connecting terminals
The terminals are designed for wire diameters of min. 0.8 mm or cross-sections of
0.5...2.5 mm
