tSC
Maximum duration for Pull Down:
(0.0 to 24h00min, res. 10 min) maximum length for Pull Down
mode.
oHE
Differential during Pull Down in energy saving mode (SET+HES+HYE+oHE):
(1.0 to 12.0°C;
1 to 21°F) this is the upper threshold limit used to activate the Pull Down in energy saving mode
SCE
Set point differential during Pull-Down in energy saving mode (SET+HES-SCE):
(0.0 to
12°C; 0 to 21°F) this is the special set-point value used during a Pull-Down function (cut-off value
for compressor). If
SCE=0
, the Pull-Down function during energy saving mode is disabled.
Con
Compressor ON time with faulty probe:
(0 to 255 min) time during which the compressor is
active in case of faulty thermostat probe. With
Con=0
compressor is always OFF.
CoF
Compressor OFF time with faulty probe:
(0 to 255 min) time during which the compressor is
OFF in case of faulty thermostat probe. With
CoF=0
compressor is always active.
7.1.2 PROBES - Prb
PbC
Probe selection:
(ntC; PtC)
ot
Probe P1 calibration:
(-12.0 to 12.0°C; -21 to 21°F) allows to adjust any possible offset of the
first probe.
P2P
Probe P2 presence:
n
= not present;
Y
= the defrost stops by temperature.
oE
Probe P2 calibration:
-12.0 to 12.0°C; -21 to 21°F) allows to adjust any possible offset of the
second probe.
P3P
Probe P3 presence:
n
= not present;
Y
= the condenser temperature alarm is managed.
o3
Probe P3 calibration:
(-12.0 to 12.0°C; -21 to 21°F) allows to adjust any possible offset of the
third probe.
P4P
Probe P4 presence:
n
= not present;
Y
= the condenser temperature alarm is managed.
o4
Probe P4 calibration:
(-12.0 to 12.0°C; -21 to 21°F) allows to adjust any possible offset of the
forth probe.

(n;Y) Enable or disable icon visualisation.
CF
Temperature measurement unit:
(°C; °F)
°C
= Celsius;
°F
= Fahrenheit.
rES
Temperature resolution:
(dE; in)
dE
= decimal;
in
= integer. NOTE: valid only for Cesius degree.
Lod
Probe default displayed:
(P1; P2; P3; P4; Set; dtr; USr)
Px
=measured value from selected
probe.
SEt

the display is updated of 1°C or 1°F after this time.
7.1.4 DEFROST - dEF
EdF

“x”. Note:
P4
=Probe on Hot Key
plug.
dtE
End defrost temperature:
(-55 to 50°C; -67 to 122°F) sets the temperature measured by the
evaporator probe (
dFP
), which causes the end of defrost cycle.
idF
Interval between two successive defrost cycles:
(0 to 255 hours) determines the time interval
between the beginning of two defrosting cycles.
MdF
Maximum length of defrost cycle:
(0 to 255 min; 0 means no defrost) when
P2P=n
(no
evaporator probe presence) it sets the defrost duration, when
P2P=Y
(defrost end based on
evaporator temperature) it sets the maximum length for the defrost cycle.
dSd
