To modify parameters or perform resets, you must enter a specific password sequence known as the "key dance".
Navigate to tst in the menu and press (display shows 888 ), then press SET again to enter the test mode. 3.2 Testing Components

Cabinet temperature has dropped below safety limits, risking product freezing.
: Usually requires accessing the advanced service menu to wipe the 7-day learning history.
To protect the compressor, the unit staggers power-up: lights first, then the compressor after 30 seconds, followed by the evaporator fan. Liquid Protection: Integrated systems to protect electrical components. Dual Probe Monitoring: To modify parameters or perform resets, you must

The controller prepares the unit roughly two hours before predicted peak traffic, ensuring product temperature is ideal for sales. Standby Mode:
The target temperature is allowed to float upward by a programmed differential (e.g., +4°C) to reduce compressor runtime. For technicians, the manual outlines a specific "key
The "Advanced" in the controller's name refers to its extensive, customizable parameter list. Accessing and adjusting these parameters is a powerful way to fine-tune the system.
While the basic manual shows you how to set a temperature setpoint, the user manual reveals the engineering parameters.
: Displayed immediately upon power-up during a parameter check.
