ENERGY MANAGEMENT SYSTEM ( EMS )
Energy Management System is a feature that enables the vendor to control the refrigeration and
light system in the machine according to the sales pattern in order to achieve the maximum
energy efficiency.
Learn-and-React
It has a built-in-feature that learns the sales pattern in the location to mark a sales-time-zone and
a no-sale-time-zone. The system reacts by regulating the illumination and refrigeration system
during the learnt time zones.
The illumination system is disabled and the products are stored at a higher temperature during
no-sales-hours.
In order to achieve set-point at the appropriate sales-time-zone, the regular refrigeration mode
will be activated 4 and half hours prior to the sales-time-zone.
