Defrost On Glass Door Coolers (Gdc) - Elstat ems55advanced Manual

The saving mode temperature is set to ensure that the cooler has sufficient time to lower the product to the ready mode tem-
perature. 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 tem-
perature.
However, the saving temperature disable (PE r) 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.
If the cooler door is opened or the motion sensor detects activity during the saving mode, ems controllers switch on the
cooler lights for the remainder of the current 30-minute period, but do not start cooling cycle.

defrost on glass door coolers (GDC)

Defrost cycles minimizes the risk of the evaporator icing up.
The defrost cycle occurs periodically as defined by the defrost interval (dE).
The defrost interval starts when the ems controller is powered up or at the end of an uninterrupted pull down.
Some ems controllers also enable defrost cycles to be started manually.
The defrost cycle ends after the time defined by the defrost duration (dd) or on reaching the defrost termination tem-
perature (dtd), as shown:
