6.8 Saving mode
EMS controllers run in the saving mode when retail outlets are closed.
In the saving mode, the product temperature is allowed to rise to a predefined temperature. The sav-
ing mode temperature range is defined by saving set point (SS P) and the saving differential (Sd).
The compressor runs until the saving set point (SS P) temperature is reached and then stops until the
measured temperature reaches the saving set point (SSP) plus saving differential (Sd) temperature.
The saving mode temperature is set to ensure that the cooler has sufficient time to lower the product
to the ready mode temperature. The EMS controller starts lowering the product temperature by the
saving restart period (Sr) before the ready mode starts ensuring that the cooler has sufficient time to
reach the ready mode temperature from the saving mode temperature.
However, the saving temperature disable (PEr) can set EMS controllers to maintain the ready mode
temperature at all times.
During the saving mode, the controller displays three dashes, (---), and the cooler lights are usually
switched off.
