pCOxs is a temperature, humidity and pressure monitoring and control controller. It can be connected to an Ethernet or Analog Bus Network and displays data via a graphic display screen or 4x20 or 6 LED displays. pCOxs can be programmed and configured via PCO hand controllers.
The Carel pCOxs manual provides detailed information on the controller’s overall features, hardware structure, and user hand‑operated interface. It includes safety warnings, installation guidelines, wiring diagrams, and technical specifications for proper setup and operation.
The document also covers network options such as pLAN and MP‑Bus, optional cards, fault diagnosis, and maintenance procedures, helping technicians and installers configure the system for various HVAC applications. This manual is written in Chinese.
