In hard cooling, both compressor and fan run continuously until rS1 temperature is reached.
From this point on, the compressor keeps switching on and off to maintain the cabinet
temperature on rS1 level.
"Hard cooling" stage completes as soon as the temperature measured with three thermal
probes reaches iS1.
Stage 2: soft cooling
Soft cooling stage starts after the completion of hard cooling stage. It is intended to prevent
the formation of a thin ice layer on food. Soft cooling continues until the temperature
measured
by three penetrating probes reaches iS2 value (usually 4 or 5 °C).
In soft cooling, cabinet temperature is controlled via cabinet temperature sensor with rS2
temperature setting (usually 0 or 1 °C / 32 or 34°F). When the cabinet temperature reaches
rS2, compressor switches on and off to maintain the cabinet temperature at this level.
Stage 3: freezing cycle
Freezing cycle: used to freeze the food quickly.
Freezing cycle starts after the completion of soft cooling stage. In freezing cycle, both
compressor and fan run continuously until rS3 temperature is reached. From this point on,
the compressor and fan keep switching on and off to maintain the cabinet temperature on
rS3 level (usually a few degrees lower than iS3). Freezing cycle stage completes once the
temperature measured with three thermal probes reaches iS3.
End of quick cooling and start of temperature maintenance:
When the temperature on one of the three thermal probes reaches iS3, End and i1P (or i2P,
or i3P) symbols are displayed on the screen.
The cycle completes once the temperature on all probes reaches iS3. This is accompanied
with an audio signal and alarm relay activation, while the screen displays "End" message and
inner cabinet temperature alternatively.
Alarm signal is turned off automatically upon the timeout defined by "but" parameter, or
forcibly by pressing any key.
At the end of the cycle, controller can activate the "temperature maintenance mode" which
keeps the inner cabinet temperature at the level defined by HdS parameter value. If HdS =
OFF, the cooling system is TURNED OFF.
NOTE 1: if dbH = yES, a defrosting cycle is run before the temperature maintenance stage.
NOTE 2: if cycle end temperature iS3 has not been reached within the maximum time
Pd1+Pd2+Pd3, the controller will continue operation displaying "OCF" alarm message on the
screen.
