Demand defrost relative delta threshold
If in configuration parameter
three stages. As a first stage the best cooling capability of the evaporator is measured after a defrost. If this
capability drops below a temperature difference configured in this parameter the next defrost is triggered.

Demand defrost absolute delta threshold
If in configuration parameter
demand is detected in three stages. As a second stage a detection is triggered if the absolute temperature
difference between Air Out and Air In drops below the value configured in this parameter. If this fails, the
defrost is triggered by time

Demand defrost delay
Time in seconds. The detection of the best cooling capability after a defrost termination is delayed by the time
configured in this parameter.
