3-digit dual display for viewing parallel operating metrics simultaneously
At its core, the EWCM 900 S is a "compressors and fans manager." It is a microprocessor-based controller specifically designed to serve as the central intelligence for a refrigeration plant's machine room. Its primary role is to coordinate and manage the operation of compressors and condenser fans—the key components that make a refrigeration system work. Beyond just switching things on and off, it monitors system pressures, handles alarms, and can even optimize energy use with scheduled operations. The "dEU" parameter allows for custom programming of
This allows installers to view and program settings interchangeably in pressure metrics () or thermal metrics ( °C/°F ). 🎛️ Interface and Programming Navigation
