Boiler Control Control System; Export Of Operational Data Via Mod-Bus Boiler Control - Viessmann Vitoflex 300-UF 530 Installation And Operating Instructions Manual

Operation
Boiler Control System
The control system for the Vitoflex 300-UF boiler firing
process (boiler control) is controlled by a Programmable
Logic Controller (PLC), which visualizes the system on a
touch screen and provides an interface for navigation and
entering settings.

Export of operational data via Mod-bus boiler control

As an option, the boiler control unit can be extended with
the Mod-bus (PYR-SED) extension module. This extension
module enables the exchange of operating data between
the higher control unit (Modbus master) and the boiler
control unit (Modbus slave) via a serial interface (RS232).
Note: This module is optional and must be ordered
separately. Please refer to the export of Operational
data via Mod-bus boiler control for details.
