Extended access authorisation
This authorisation status allows access to
all
heating circuits and
to the hot-water circuit and their parameters and switching times
within the respective central device
Landlord status
Once a wall device is connected and registered via the data bus
to the central device, the central device automatically switches to
remote operating mode! This is necessary to ensure clear
operation of the system with connected wall devices.
7.3.12 Cascading of heat generators in the bus system
7.3.12.1 General description of cascading of control devices
In its standard version the control system features the possibility
to couple and cascade several boilers. The cascade control is
independent of the type of heat generators to be combined. For
instance, condensing boilers can be easily combined with
atmospheric gas boilers.
The system automatically recognises a cascade by checking if
several central devices have programmed a heat generator, or if
more than one condensing boiler is connected to a central device.
In cascade operation an additional cascade selection level is
displayed for handling the parameters in the central device
assigned to bus address 10.
Cascade operation excludes 2-stage boiler control. All available
stages are operated by the cascade management. Consequently,
the respective parameters of the "Heat Generator" menu are not
available. All control is now governed by cascade control.
