Standard value of the cycles
Cy1: for fast chilling and conservation of foods at positive temperature
CyS = tEP iS2 = 5°C Pd3 = OFF
dbC = yes rS2 =+2°C dbH = yes
iS1 = 8°C Pd2 = 3.0 h HdS = 2°C
rS1 = -10°C iS3 = 5°C
Pd1 = 2.0 h rS3 =+2°C
Cy2: for chilling and fast freezing of foods with holding
CyS = tEP iS2 = 5°C Pd3 = 4.0 h
dbC = YES rS2 = +2°C dbH = YES
