The condenser temperature probe is failing. This sensor prevents the system from overheating due to blocked airflow.
Safety is paramount during installation. Disconnect the main power supply before handling any electrical connections. Mount the controller securely away from direct moisture, extreme heat sources, or high-voltage lines that could introduce signal interference. Terminal Wiring Configuration Main AC Power Input (Live and Neutral).

The Elstat EMS 25 Advanced is an intelligent energy management system designed specifically for commercial refrigeration units. By monitoring ambient temperature, door openings, and usage patterns, this controller automatically switches your cooler into an eco-mode during periods of inactivity.
In the world of commercial refrigeration and HVAC control, precision is not just a luxury—it is a necessity. The stands out as a premium electronic thermostat, renowned for its robust build quality, energy-saving capabilities, and versatile programming options. However, to unlock its full potential, moving beyond the basic quick-start guide is essential. This Elstat Ems 25 Advanced Manual is your comprehensive resource for installation, deep configuration, troubleshooting, and performance optimization. Elstat Ems 25 Advanced Manual
The display will flash, clearing the self-learning matrix and restarting its baseline learning period.
Increases parameter values or cycles backward through diagnostic menus.
The front panel interface features a 3-digit, 7-segment LED display coupled with physical control buttons and vital status indicators.
The Elstat EMS 25 Advanced features a hidden parameter menu to prevent unauthorized tampering. Accessing this menu allows technicians to customize temperature setpoints, differential values, and defrost intervals. How to Access the Parameter Menu The condenser temperature probe is failing
The EMS 25 operates on a differential algorithm. Unlike mechanical thermostats that use a bimetallic strip with wide hysteresis, the EMS 25 uses a programmable differential (hysteresis) to cycle the compressor on and off based on the sensor reading relative to the setpoint.
The allowable temperature rise before the compressor kicks back on. Saving Setpoint (Economy) 8.0°C (46.4°F)

The primary air temperature sensor is open-circuit or short-circuited. Check wiring connections or replace the sensor.
To modify settings or view parameters, you must enter a specific button sequence known as the "key dance" to bypass the password () prompt:
The EMS 25 is designed as a direct replacement for mechanical thermostats, offering a form factor that fits standard mounting holes (often 29x71mm or similar industry standards) found in many commercial cabinets.
Verify the PIR sensor lens is clean and free of dust, grease, or point-of-sale signs that block its line of sight.
