Setup & configuration
Refrigeration parameters organized by function
Authorized setup screens bring setpoints, defrost, schedules and alarm limits into a structured control view for each refrigeration unit.
Historical graphs & trends
Understand what happened before the service call
Live readings tell you what is happening now. Historical trends show how the system reached that condition and help technicians isolate intermittent problems faster.
- Temperature history and pull-down performance
- Refrigeration and compressor cycles
- Defrost duration and recovery
- Fan operation and equipment state history
- Humidity and pressure trends when available
- Time correlation between doors, alarms and temperature
