The (including the EMS 25 Plus and EMS 25R variants) is an intelligent Energy Management System (EMS) controller designed to maximize energy savings in commercial refrigeration units. Used extensively by major global brands like Heineken and Coca-Cola, the controller utilizes a self-learning algorithm, motion sensors, and door switches to predict foot traffic and dynamically shift between high-performance cooling and energy-saving modes.
But the restaurant owner was screaming through his phone. Leo gritted his teeth, entered the hidden menu again, and set P.28 to 1.

Enter the password sequence (e.g., Press Set 4x, Up 1x, Down 2x, Defrost/Teach 2x). Navigate through parameters like (Set Point), (Differential), and (Celsius/Fahrenheit toggle). Key Technical Specifications Input Supply 12VDC from a separate Power Supply Module (PSM) The (including the EMS 25 Plus and EMS
He’d installed hundreds of these electronic controllers. Set the temperature, defrost cycles, maybe a probe calibration. Basic stuff. But this manual was different. He’d found it jammed behind a condenser coil six months ago, its pages stained with what looked like coffee… or something older. It was thicker than the standard manual. Much thicker.
Configurable values include the SPC/SPF (Set Point), SSP (Saving Set Point), and dE (Defrost Interval). 5. Troubleshooting & Alarms
A clean condenser coil is essential for efficient operation. Leo gritted his teeth, entered the hidden menu
If an EMS 25 controller is moved to a new retail establishment with different operating hours, its learned memory matrix must be cleared so it can accurately track new customer foot-traffic patterns.
: The compressor ran continuously for the duration set in parameter Ct without reaching the targets. Check for low refrigerant charge, blocked condensers, or leaky door gaskets. Ht Condition : Condenser Over-Temperature Alarm.
The target temperature setpoint is automatically raised by a configured margin (e.g., +3°C) to reduce compressor runtime.
