Control functions via the bus

9.1.2.1

Boiler corrosion protection

If the heat generator is working with boiler corrosion protection, then this status is sent to all corresponding
heating circuits. These will then block the energy supply for the time being (valves closed and pumps off).
9.1.2.2

Indirect return temperature control

The heat generator in the central controller (ADR 10) sends its current boiler data to each mixing circuit in
the system which can then activate an indirect return control.
9.1.2.3

Accumulator mode (accumulator priority mode)

Every standard unit can charge the accumulator as long as the device type is suitable. While charging in
priority mode, the charge blocks all other heating circuits and charging in the bus system. If the accumulator
is charged in parallel mode, all heating circuits in the system can keep running and other charging can also
be activated in parallel mode.
9.1.2.4

Heating demand

Each heating demand in the data bus system will be processed by the central controller (ADR 10). The
highest demand is accepted and transferred to the heat generator as a setpoint. Manual operation with
manual temperature settings is also regarded as demand.
9.1.2.5

Clock synchronisation

The time of the central controller (address 10) will be synchronized in the complete system. There is a
system time.
9.1.2.6

Room temperature information

All wall units and room sensors send the current room temperature to their heating circuits regularly.
9.1.2.7

Errors/ status indications

Errors and status indications will be sent from every standard unit to the wall modules for display.
