Тия от МЕ защо не си пишат дефрост алгоритъма за новите модели. За стари модели го пишат
5. Defrosting
(1) Starting conditions of defrosting
When the following conditions a) ~ c) are satisfied, the defrosting starts.
a) The defrost thermistor reads -3°C or less.
b) The cumulative operation time of the compressor has reached any of the set valuesw (30, 35, 40, 45, 55, 65, 75, 85,
95, 105, 115, 125, 150 minutes).
c) More than 5 minutes have passed since the start-up of the compressor.
w Set value of compressor operation time(hereinafter referred to as defrost interval)
This is decided by the temperature of defrost thermistor and ambient temperature thermistor, the previous defrosting
time. For example, the first defrost interval is 40 minutes long, and the second is 45 minutes long. The third and subsequent
intervals are set to be longer, and less frequent, depending on defrosting time.
The third and subsequent defrost intervals follow any of the three patterns …5 or 10 to 20 minutes longer, the same,
or 5 or 10 to 20 minutes shorter compared with the previous defrost interval … with the longest 150 minutes and the
shortest 30 minutes
