pCO > XS has been designed specifi cally to provide the functions of the pCO sistema family programmable controllers to all those applications that are covered only by parametric controllers. Thanks to this new controller, the control software for single-circuit chillers and heat pumps, small roof-top units and precision air conditioners can be quickly customised based on each manufacturers requirements. The characteristics of the pCO > XS perfectly suit the requirements of the manufacturers of air-handling units. Indeed, a dedicated version with Belimo MP-Bus protocol is now available, which allows all the servo controls on the unit to be connected directly to the controller via a simple 3-wire cable. Furthermore, the pCO > XS ensures complete compatibility with all the current pCO sistema user interfaces (pLD , pGD > 0-1 and pGD > 2-3 ), with all the pCO sistema controllers (pCO > 3 , pCO > 1 , pCO > C , pCO > 1 ), with all the pLAN modules (FCM speed control modules, EVD drivers for electronic expansion valves, pAD room terminals). The compact dimensions (8 DIN modules), the number of inputs/outputs (18 in total), and the wide range of accessories that has always been one of the strengths of the pCO sistema controllers, make the new > XS controller a versatile and competitive solution for all air-conditioning OEMs. >
