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).
