3.2 DEFROST MODE
3.2.1 STANDARD DEFROST
Depending on the requirement, defrost can be triggered by either using the temperature or/and by time, when both settings are
enabled, whichever event happens first will trigger or end the defrost cycle.
The FDEx2 has a minimum defrost duration and minimum duration between defrost cycles which must be satisfied before it will
act no matter the status of the other parameters. This is to ensure the defrost cycle is not stopped too early or defrost cycles are
not initiated too close together.

3.3 ENERGY SAVING MODE
The FDEx2 has an Energy Saving mode that provides reduced compressor operation when the outlet is closed and no
customer demand by setting the cut-in and cut-out temperatures higher than in normal mode. When the FDEx2 does not
sense a door opening for the pre-set duration, then the FDEx2 will enter Energy Saving Mode and run using the energy-saving
cut-in and cut-out temperature. When the door is opened or the maximum energy-saving timer has elapsed, the FDEx2 will
resume normal operation.
