System bus
The heating system
This controller can be expanded in a modular fashion
using additional modules that are connected via the
integrated bus. In its maximum configuration, the system
can be used to control the following heating system
components
1-8 Boiler (modulating or switching)
1-15 Mixed weather-dependent heating circuits
0-15 Room controller (digital or analogue)
1
Solar system (2 collectors, 2 storage tanks)
1
Solid fuel boiler
The various components are simply coupled to the system
bus. The modules log on to the system automatically and
search for their communication partners via the defined
bus IDs (heating circuit number or boiler number).
