2CC
Activation mode for 2nd compressor (valid if oAx=CP1 and oAy=CP2):
(FUL; HAF)
FUL
=second
compressor will be activated after
AC1
delay.
HAF
=second compressor will be activated with step
logic.
rCC
Enable compressor rotation:
(n;Y)
n
= CP1 is always the first compressor activated.
Y
= CP1 and
CP2 activation is alternated.
MCo
Maximum time with compressor ON:
(0 to 255min) maximum running time for ONOFF
compressor. With
MCo=0
this function is disabled.
rtr Regulation percentage=F(P1; P2) (100=P1; 0=P2):
100=P1 only; 0=P2 only
CCt
Maximum duration for Pull Down:
(0.0 to 23h50min, res. 10min) after elapsing this interval of time,
the super cooling function is immediately stopped
CCS
Pull Down phase differential (SET+CCS or SET+HES+CCS):
(-12.0 to 12.0°C; -21 to 21°F) during
any super cooling phase the regulation SETPOINT is moved to
SET+CCS
(in normal mode) or to
SET+HES+CCS
(in energy saving mode)
oHt
Threshold for automatic activation of Pull Down in normal mode (SET+HY+oHt):
(1.0 to 12.0°C;
1 to 21°F) this is the upper limit used to activate the super cooling function.
oHE
Threshold for automatic activation of Pull Down in energy saving mode
(SET+HES+HYE+oHE):
(1.0 to 12.0°C; 1 to 21°F) this is the upper limit used to activate the super
cooling function.
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
CY=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
Cn=0
compressor is always active.

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
= present.
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 defrost present.
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
= present.
o4
Probe P4 calibration:
(-12.0 to 12.0°C; -21 to 21°F) allows to adjust any possible offset of the forth
probe.
5.1.3 Visualization parameters - diS
CF
Temperature measurement unit:
(°C; °F)
°C
= Celsius;
°F
= Fahrenheit.
rES Temperature resolution:
(dE; in)
dE
= decimal;
in
= integer.
Lod
Probe default displayed:
(P1; P2; P3; P4; SEt; dtr; USr)
Px
=probe “x”;
SEt
=set point;
dtr
=do not
use it.
rEd

(P1; P2; P3; P4; SEt; dtr; USr)
Px
=probe “x”;
SEt
=set
point;
dtr
=do not use it.
dLY
Temperature display delay:
(0.0 to 20min00sec, res. 10 sec) when the temperature increases, the
display is updated of 1°C or 1°F after this time.
dtr
Probe visualization percentage, F(P1; P2):
(0 to 100)
with
dtr=1
the display will show this value
VALUE=0.01*P1+0.99*P2
