Cn= runs in parallel with compressors, OFF during defrost;
o-Y = continuous mode, on during defrost;
C1y= runs in parallel with the first compressor, on during defrost;
C2y= runs in parallel with the second compressor, on during defrost;
Cy= runs in parallel with compressors, on during defrost;
FSt Fan stop temperature: (-50÷50°C/°F; res. 1°C/1°F).It used only if the EPP = yES. If the temperature.
detected by the evaporator probe is above FSt fans are stopped. It serves to avoid blowing warm air
in the room.
AFH Differential for the stop temperature and for the alarm (0.1 ÷ 25.0 °C; ris.0.1°C/1°F) Fans carry
on working when the temperature reaches the FSt-AFH value, the temperature alarm recovers when
the temperature is AFH degrees below the alarm set.
Fnd Fan delay after defrost: (0 ÷ 255 min) The time interval between end of defrost and evaporator fans
start.
TEMPERATURE ALARMS
ALU MAXIMUM temperature alarm (it is used only during the holding phase): (1 ÷ 50 °C/°F) When
the “SET+ALU” temperature is reached the alarm is enabled, (possibly after the “ALd” delay time).
ALL Minimum temperature alarm (it is used only during the holding phase): (1÷50°C/1°F) When the
“SET-ALL” temperature is reached the alarm is enabled, (possibly after the “ALd” delay time).
ALd Temperature alarm delay (it is used only during the holding phase): (0÷255 min) time interval
between the detection of an alarm condition and alarm signalling.
EdA Temperature alarm delay at the end of defrost (it is used only during the holding phase): (0 ÷
255 min) Time interval between the detection of the temperature alarm condition at the end of defrost
and alarm signalling.
tbA Silencing alarm relay: (Yes= silencing buzzer and alarm relay, no= only buzzer silencing).

1. Every programmable cycle Cy1, Cy2, Cy3 or Cy4 can be divided into up to 3 phases usually called:
