Air conditioner control PCO5

The new proposal from CAREL in its range of programmable controllers is the result of continual improvements in more than 25 years' experience in the development of controllers for the HVAC/R market. Compared to the current family of pCO controllers (pCO3), the pCO5 has been enhanced with specific new functions to improve the efficiency of HVAC/R systems, such as integration of the electronic expansion valve driver, with ultra cap technology that guarantees the valve is closed in the event of power failures. In addition, the pCO5 offers more demanding designers up to five serial lines, three of which are always available and allow the protocol to be configured, plus two optional lines that can be configured in terms of both the protocol (Modbus®, BACnet™, CAREL, CANbus, Konnex LON) and the physical support (RS485, Ethernet, CAN, Konnex, Echelon®). Versions are available with both "Host" and "Device" USB ports for connecting a standard USB pendrive and connecting directly to a PC without needing serial coverters. Integration of these functions brings various benefi ts to manufacturers and designers of HVAC/R systems, including: • less wiring, as the EXV driver modules, battery charger modules and backup battery modules have been replaced in the pCO5 by the built-in EXV driver with ultra cap technology guaranteed closing of the valve in the event of power failures, thanks to ultra cap technology.
