HEATING (OSH<0): second compressor cut IN is OSS-OAH. Second compressor cut out is when the
temperature OSS.
OSi Probe selection for the second compressor: rP=thermostat probe; EP=evaporator probe; tiM=cycle
count down; i1P=insert probe 1; i2P=insert probe 2; i3P=insert probe 3.
tdF Defrost type (not present in the XB350C): rE=electrical heater; in=hot gas.
idF Interval between defrost cycles: (0.1 to 24h00min, res. 10 min) determines the time interval between
the beginnings of two defrost cycles.
dtE Defrost termination temperature: (-50 to 50; res. 1°C or 1°F) sets the temperature measured by the
evaporator probe, which terminates the defrost. Used only if EPP=YES.
MdF Maximum length for defrost: (0 to 255 min) when EPP=no (timed defrost) it sets the defrost duration,
when EPP=YES (defrost termination based on temperature) it sets the maximum length for defrost. If
MdF=0 the defrost is disabled.
dFd Temperature displayed during defrost: (rt; it; SEt; dEF) rt=real temperature; it=temperature at the
start of defrost; SEt=set point; dEF="dEF" message.
Fdt Drip time: (0 to 60 min) time intervals between reaching defrost termination temperature and the
restoring of the controllers' normal operation. This time allows the evaporator to eliminate water drops
that might have formed during defrost.
dAd Defrost display time out: (0 to 120 min) sets the maximum time between the end of defrost and
the restarting of the real room temperature display.
FnC Fans operating mode during the holding phase:
o-n=continuous mode, OFF during defrost;
C1n=runs in parallel with the first compressor, OFF during defrost;
C2n=runs in parallel with the second compressor, OFF during defrost;
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 to 50, res. 1°C or 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 to 25.0°C, res. 0.1°C or 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 to 255 min) the time intervals between ends of defrost and evaporator fans
start.
ALU MAXIMUM temperature alarm (it is used only during the holding phase): (1.0 to 50.0, res. 0.1°C or
1°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): (1.0 to 50.0, res. 0.1°C or
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 to 255 min) time interval
between the detection of an alarm condition and alarm signalling.
EdA Temperature alarm delay at the end of a defrost (it is used only during the holding phase): (0 to
255 min) time interval between the detection of the temperature alarm condition at the end of defrost
and alarm signalling.
tbA Silencing alarm relay: Y=silencing buzzer and alarm relay; n=only buzzer silencing.
tCy Duration of the last cycle (read only).
tP1 Duration of first phase of the last cycle (read only).
tP2 Duration of second phase of the last cycle (read only).
tP3 Duration of third phase of the last cycle (read only).
