: Automated cycles to prevent ice buildup on the evaporator. Accessing the Programming Menu
The final page of the Advanced Manual had one last line, printed so small he’d missed it a hundred times:
The (often referred to in technical documentation as the EMS 25 Plus ) is a sophisticated refrigeration controller designed to optimize energy efficiency through intelligent "self-learning" technology. This controller identifies peak and off-peak periods of use to adjust cooling and lighting accordingly, potentially reducing energy consumption significantly in commercial settings. 1.

: The unit cycles at a warmer temperature and turns off lights during periods of inactivity.
The controller displays specific codes when it detects a system failure or sensor issue. : Automated cycles to prevent ice buildup on the evaporator
The display shows real-time temperature (e.g., "3.0") or status messages like "USE" (ready mode) or "---" (saving mode) depending on the configuration.

The target temperature is allowed to float higher than normal to save compressor wear and electricity.
