8.6 Control systems
Digital control system for the energy-optimised operation of
decentralised indoor climate systems:
■ System set up according to OSI reference model
■ Onsite connection to the individual control modules using
novaNet system bus in a serial topology
■ Cross-communication with equal priority (peer-to-peer/
multiplier) using novaNet log
■ Fast reaction times due to data transmission on an events
basis
■ Control modules pre-addressed in the factory with
integrated lightning protection and battery-buffered RAM
modules
■ No onsite engineering (binding) required
