CAREL pCO5 — model-specific controller selection

CAREL’s original pCO5 family is a programmable controller for chillers, heat pumps, rooftop equipment and HVAC/R. Small/Medium/Large/Extralarge hardware configurations have different I/O counts, analog and passive probe interfaces, digital/SSR outputs, pLAN serial communication and optional local terminals. The installed program determines operating functions; the physical controller alone is not a pre-certified chiller control application.

Confirm supply, software revision, terminal map and fieldbus cards for the exact pCO5 order number. A later pCO5+ may have different memory and connector choices and is not automatically wire-compatible.
