Eliwell Ewcm 900 S May 2026

The Eliwell EWCM 900 S is a type of controller used in refrigeration systems, particularly in commercial and industrial settings. Here's some general information about it:

  • A 4-digit LED display for clear temperature readings.
  • Intuitive navigation keys.
  • Visual alarms that alert users immediately when parameters fall out of range (e.g., high temp or sensor failure).
  1. Probe Placement is Key: The ambient probe must be in the return air stream, and the defrost probe (if used) must be mounted securely to the evaporator fins at the coldest point.
  2. Digital Input Programming: A common mistake is not configuring the digital input. Use parameter i1F to define whether it’s a door switch (d0), alarm input (AL), or disabled (nu).
  3. Relay Allocation: Verify the 16A relay is used for the compressor. Inductive loads (motors) have a higher inrush current; use a contactor for larger compressors despite the 16A rating.
  4. Parameter Backup: The controller does not have a built-in memory card. Always note down key parameters (St, Hy, dtE, dCt, LFd, ALU, ALL) before replacing a unit.
