Industrial PCO3ST0AL0 E2 Microprocessor Controller

The PCO3ST0AL0 E2 Microprocessor Controller is a 24V, microprocessor‑based control module built for STULZ E2 series equipment, marrying CAREL pCO3 technology with STULZ hardware to govern HVAC and refrigeration applications. It uses a pCO3 core (Large variant) and stores both the control program and configuration in FLASH‑MEMORY and E2PROM, so settings persist through power interruptions. Programming and configuration are performed via a PC using the WINLOAD32 utility or with a dedicated programming key, with loading speeds supported at 28.8 kbps and 115.2 kbps. The unit offers expansion connections through optional boards to attach field devices such as valves and I/O modules, enabling tailored control of complex cooling systems. This Rev. 2.011 version is clearly identified as a 24V‑powered STULZ/Carel collaboration, designed for industrial cooling applications that require configurable, robust microprocessor control.
