GENERAL CHARACTERISTICS is a microprocessor-based electronic controller compatible in both hardware and software terms with the pCO family. Developed by REHAU in compliance with the European RoHS directives, it provides a solution for many applications in the air-conditioning and refrigeration sectors. It ensures absolute versatility, allowing specific products to be created to customer request.
Connectors Example of coding: PCO3CON*** , see the following table for the description: PCO3CON * 0 = screw S = small 1 = spring M = medium L = large Z = extra large N.O. C = extra large N.C. TECHNICAL SPECIFICATIONS Mechanical characteristics dimensions...

PRELIMINARY NOTES FOR THE INSTALLER: COMPARISON BETWEEN pCO AND pCO • the pCO family controllers do not have the connector using the programming key code PCO201KEY0. To program the controller, use the new Smart Key (PCOS00AKY0) available from September 2005. Otherwise use WinLoad ver.

• to exit the configuration procedure and save the data, select the field “OK ?” and set to Yes, then confirm by pressing the button. The fields in the “Adr” column represent the addresses of the terminals associated with the pCO3 board address 12, while the Priv/Shared column indicates the type of terminal. Important: the pGD terminals cannot be configured as “Sp” (shared printer), as they do not have the printer output. If the terminal remains inactive (no button pressed) for more than 30 seconds, the configuration procedure is automatically ended without saving any changes.
