5.2 General Characteristics
System 2500 is a microprocessor-based electronic controller developed in compliance with the
European RoHS standards. It provides a solution for many applications in the air-conditioning and
refrigeration sectors ensuring absolute versatility, allowing specific products to be created to
customer request. The controller runs the control program, and is fitted with the set of terminals
required for connection to the devices (compressors, fans, etc.). The program and the parameters
are saved to FLASH-MEMORY and E2prom for safe keeping even in the event of a power failure
(without requiring a backup battery). The controller also allows connection to the pLAN (Private
Local Area Network) and can be connected to other System 2500 controllers. All the controllers in
the pLAN can exchange information (variables, digital or analogue, depending on the application
software used) at high transmission speed. Up to 32 units can be connected via RJ45 interface.
