Running time defrost (par. d10, d11, d20)
Running time is a special function that determines when the refrigeration unit needs defrosting. In particular,
it is assumed that if the evaporator temperature measured by defrost probe
Sd
remains continuously below
a certain set threshold
(d11)
for a certain time
(d10)
, the evaporator may be frozen and a defrost is activated.
The time is reset if the temperature returns above the threshold.
Parameter
d20
sets the unit of measure (hours or minutes) used to count the times for parameter
d10
(defrost
"running time").
