The evaporator fan management differs according to the cycle in use, as specified below. The way the evaporator fan is
managed changes depending on the presence of the evaporator probe, which is enabled setting parameter P4 to 1.
Blast chilling, blast-freezing, conservation, ice cream hardening, customized and continuous cycles, pre-
cooling
The fans are always switched on and are only switched off if the cabinet temperature is above the value of parameter
F17 and/or if the evaporator probe temperature is above the value of parameter F1. They are only switched on again if
the cabinet temperature falls below the F17-F8 value and that of the evaporator probe falls below F1-F8.
Conservation
During conservation, the fans are managed according to parameter F49. If set to 0 (default), the fans will work in parallel
to the compressor, if set to 1, the fans will always be active.
Sanitation (blast chilling and holding)
The fans are always switched on and are only switched off if the cabinet temperature is above the parameter F17 value
and/or the evaporator probe temperature is above the parameter F1 value. They are only switched on again if the cabinet
temperature falls below the F17-F8 value and that of the evaporator probe falls below F1-F8.
Sanitation (conservation)
The fans are always managed in parallel with the compressor.
Thawing
The fans are always active.
Defrosting
During defrosting the evaporator fans are switched off if the parameter d1 value is set to 0 or 1. They are switched on
if d1 is set to 2 or if the door is open with d1 set at 3.
At the end of the defrosting cycle, the fans remain off for the time set by parameter F3, once the drip time set by
parameter d16 has elapsed.
Proofing (blast chilling)
The fans are always switched on and are only switched off if the cabinet temperature is above the parameter F17 value
and/or the evaporator probe temperature is above the parameter F1 value. They are only switched on again if the cabinet
temperature falls below the F17-F8 value and that of the evaporator probe falls below F1-F8.
Proofing (re-awakening, proofing, conservation)
The fans are always active.
Slow cooking and holding
During slow cooking, the fans will be managed according to parameter F50. If the parameter is set to 0 (default), they
will always be active. If set to 1, they will be active when heating elements are ON, while they will be switched on the
basis of ON-OFF cycles (parameters F51 and F52) when the heating elements are OFF.
