The indicated energy efficiency classification can be attained only if the fol-
lowing functions are implemented:
V Integrated individual room control including demand control “by occupancy‚
air quality‚ etc.” (Heating circuits for precontrol in individual room control)
V Indoor temperature control (Room temperature in individual room control via
KNX requires extra configuration)
