Eliwell Ewcm 900 S [2026]

: Compatible with common gases including R22, R134A, R404A, R407C, and R507. Eliwell France Programming & Operation The controller uses two levels of programming: Operating (oPr) : Accessible by pressing Configuration (CnF) : Accessible by pressing PRG (twice) + UP Eliwell France

Racks utilizing identical compressors equipped with capacity control valves (stepped partialisation).

The controller uses a dual-level programming interface: an menu for daily adjustments and a Configuration ("CnF") menu for deep system setup. Users can navigate these via the front keypad, which includes a double 3-digit display to show real-time data like compressor status and run times. For integration into broader monitoring networks, it features an RS-485 serial port for connection to the Eliwell Televis system .

With rising energy costs, the controller’s efficiency features are vital. The unit supports "Eco" modes and Night & Day setpoints, allowing the system to relax temperature constraints during non-operational hours (like overnight) to save significant power.

, here is the standard approach:

: It offers "normal" and "economy" setpoints, which can be toggled to optimize performance or energy use. System Reliability and Safety

Typically 24Vac/dc or 230Vac (depending on the specific model variant). : Compatible with common gases including R22, R134A,

Optimizes setups where compressors have different cooling capacities, engaging the most efficient combination to match the load. 2. Inverter and Digital Scroll Integration

Establishes the proportional band and integration time for head pressure control. Users can navigate these via the front keypad,

The controller balances robust hardware reliability with flexible software algorithms. It optimizes the COP (Coefficient of Performance) of the compressor rack while minimizing mechanical wear. Technical Parameters
