2 Operation
Synco™ 700 devices may only be operated by staff who have been instructed by
SBT HVAC Products or their delegates and whose attention has been drawn to
potential risks.
2.1 Functions of the bus operator unit
The RMZ792 bus operator unit is used to make all settings and readouts required for
operating a device. All entries made on the bus operator unit are transmitted to the
respective device where they are handled and stored; the operator unit itself does not
store any data. The information required by the user is generated by the devices and
transmitted to the operator unit for display. The text catalog in different languages and
the description of the operating structure of all operable Synco™ 700 devices are
stored locally on the exchangeable memory card (RMA792) in the operator unit.
2.2 Operating concept
On the software side, all settings and readout values are arranged as datapoints (oper-
ating lines) of the menu tree. Using the operating elements, every datapoint can be
selected, displayed or set. All menus appear on the LCD as clear-text.
The bus operator unit has several languages preprogrammed; when commissioning the
plant, the required language must be activated. The Operating Instructions for the user
are integrated in the Installation Instructions (G3113).

To ensure trouble-free functioning of the bus operator unit, compatible software versions
of the different types of communicating units must be combined. For compatible units and
versions, refer to document J3100 (Synco™ 200 / Synco™ 700 Valid Version Set).
3.2 Remote operation and local operation
The bus operator unit provides access to the datapoints of the bus users’ user
and service levels. But the datapoints of the bus users’ password level are to be
accessed via the local RMZ790 and RMZ791 operator units. For this reason, the
RMZ792 bus operator unit cannot be used for configuring and commissioning
plant.
3.3 Navigating on the device list
During commissioning, the device list (list containing all bus users) is generated. Data-
points are always to be accessed via the device list – with the exception of the favorite
pages (refer to section 3.4 “Quick access with favorites”). By selecting the required unit
from the device list, the operator reaches the menu tree of the unit needed.
Menu tree and navigation are not any different from local operation with the
RMZ790 or RMZ791.
When pressing the INFO button during navigation, the following information is displayed:

16/52
Building Technologies Bus operator unit RMZ792 CE1P3113en
HVAC Products 3 Operation of devices 03.04.2006
•The device name and – if appropriately set – the device address
•The current position in the menu tree (path)
•Long text relating to the selected datapoint
The information is displayed as long as the button is kept depressed.
3.4 Quick access with favorites
The favorite pages provide a user interface matched to the requirements of every day
use. On the favorite pages, simple datapoints of any devices from the device list can be
combined. From their location in the menu tree of the respective device, the datapoints
are copied to the required favorite page. This makes navigation much more efficient. All
favorite pages are identified by the symbol in the corner at top right. This makes it
easy to distinguish between favorite pages and the unit’s menu tree.
3.5 Information describing what is visible
Certain Synco devices deliver information that describes what is visible. When using
this information, the user interface only displays datapoints that are important for the
controller’s current configuration.
If a device does not support this kind of information, the bus operator unit will display all
available datapoints – independent of the device’s configuration. For this reason, data-
points may assume values that do not make sense and setting values may not trigger
any actions because the device’s current configuration does not support them or they
are inactive.
The following types of devices do not contain information describing what is visible:

3.7 User-defined text
User-defined text from the devices is adopted, which means that the display on the bus
operator unit is identical with that on the local operator unit (RMZ790 / RMZ791). The
bus operator unit reads the user-defined text from the respective device. The RMZ792
displays the default text until the text from the device is received.

•Via the service interface of a Synco™ controller (not recommended)
•When using the cable supplied with the bus operator unit, plug correctly the RJ45
connector into the appropriate socket of the RMZ792 (audible click)
•Move the KNX / EXT slide switch for selecting the type of power supply to its end
position
4.1 Power supply via Konnex bus
•If the bus operator unit is used in a location where AC 24 V power supply is not
available (mobile use, installation in some other space), the unit can be powered via
the Konnex bus
•Power supply must be such that 45 mA are available for the bus operator unit. This
necessitates at least 2 active decentral bus power supplies via Synco™ controllers
or 1 central bus power supply
•The slide switch at the rear of the bus operator unit must be set to KNX
•Using the cable supplied with the unit, the RMZ792 is to be connected to a Konnex
bus socket (figure a) or a Synco™ controller (figure b)
•The Konnex bus cable is to be connected to terminals CE+ and CE– on the base
(figure c; observe polarity)

4.2 External power supply
•External AC 24 V power supply is recommended in the case of fixed installations
(e.g. in the control panel door). This means that the decentral / central bus power
supply does not have to carry the load of the bus operator unit and can be used for
powering other bus users
•The slide switch at the rear of the bus operator unit must be set to EXT
•AC 24 V is supplied to the bus operator unit via terminals G and G0

4.3 Power supply via Synco™ controller
•In exceptional cases, the bus operator unit can also be powered via the service
interface of a Synco™ controller. Because of the additional power consumption of
the bus operator unit, this type of power supply is possible only if the controller is
equipped with no more than 3 extension modules
•The slide switch at the rear of the bus operator unit must be set to EXT
•The bus operator unit is to be connected to the service interface of the Synco™
controller using the cable supplied with the unit

If the bus operator unit is connected while the controller is in operation, the extension
modules might deliver fault status messages. The faults may lead to short-time interrup-
tions of plant operation. The fault status messages must be acknowledged and reset.
4.4 Error handling
Possible cases are:
Error Cause / remedy
Bus operator unit does not start
Bus operator unit is cyclically
restarted
Konnex bus is locked
Operating values of the bus users
are not correctly displayed or
cannot be changed
Backlit display very faint
•Wrong polarity CE+ / CE–
•Wrong polarity G / G0
•Insufficient power supply via Konnex bus
(undersized bus power supply, too low bus
voltage)
•Wrong slide switch position (KNX / EXT) or
switch in an inadmissible intermediate position
•RJ45 connector not correctly plugged in (no
contact)
Controller indicates failure of
extension modules, parts of the
plant fail
The slide switch is in the EXT position and the
bus operator unit was connected while the
controller was in operation.
Remedy:
1. Acknowledge the fault status messages and
reset them.
2. Connect the bus operator unit to a controller
with no extension modules or switch on the
controller only after the bus operator unit
has been connected.
