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 (
S S P
) and the saving differential (
S d
).
The compressor runs until the saving set point (
S S P
) temperature is reached and then stops until the
measured temperature reaches the saving set point (
S S P
) plus saving differential (
S d
) 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 (
S r
) 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.
