TELEMANAGEMENT
amplifiers & converters
''by setting up a network of amplifiers, converters and modems (normal or GSM) it is possible to realise a telemanagement system with an unlimited number of electronic devices with distance reaching hundreds of kilometres. This network can be implemented using normal electric cables laid with the DISTRICT HEATING pipework. The need for modems and telephone lines is drastically reduced.''
