BUS J-Y(ST)YH 2 X 2 X 0.8

Application

Installation and operation of Building Management System requires wide range of technologies. Control, monitoring and optimization of the various functions and services include heating and cooling, ventilation, lighting, indicator boards, blinds and often the management of electric appliances. The basic control technologies have been in existence for some time. Systems are available in various degrees of complexity, ranging from the timer-controlled water heater or thermo static radiator valves (TRVs), to the so-called “intelligent houses” which manage according to prearranged efficiency criteria, everything from safety and security systems to air conditioning, and from lighting and ventilation systems to telematic services and domestic appliances. The EIB-BUS cable is used for the transmission of bus signals for intelligent automation systems in buildings.
