PARAMETER LIST
REGULATION

AC Anti-short cycle delay:
(0÷30 min) interval between the compressor stop and the following
restart.
CCt Thermostat override:

be used, for instance, when the room is filled with new products.
Con Compressor ON time with faulty probe:
(0÷255 min) time during which the compressor is active
in case of faulty thermostat probe. With COn=0 compressor is always OFF.

in case of faulty thermostat probe. With COF=0 compressor is always active.
CH Type of action:
CL = cooling; Ht = heating.
DISPLAY
CF Temperature measurement unit:
°C = Celsius; °F = Fahrenheit. When the measurement unit is
changed the SET point and the values of some parameters have to be modified.
rES Resolution (for °C)
: (in = 1°C; de = 0,1°C) allows decimal point display.
dE
= 0,1°C;
in

DEFROST
EdF Defrost mode:
in
=
interval mode
. The defrost starts when the time “
Idf
” is expired.
Sd
=
Smartfrost mode
. The time IdF (interval between defrosts) is increased only when the
compressor is running (even non consecutively) and only if the evaporator temperature is less
than the value in "
SdF
” (set point for SMARTFROST).
IdF Interval between defrosts:
(1÷120h) Determines the time interval between the beginning of two
defrost cycles.
MdF (Maximum) duration of defrost:
(0÷255 min) When
P2P = n
, no evaporator probe, it sets the
defrost duration, when
P2P = y
, defrost end based on temperature, it sets the maximum length for
defrost.
dFd Display during defrost:
rt
= real temperature;
it
= temperature reading at the defrost start;
Set
= set point;
dEF
= “dEF” label;
dEG
= “dEG” label;
dAd Defrost display time out:
(0
255 min) Sets the maximum time between the end of defrost and
the restarting of the real room temperature display.
dPO First defrost after start-up:
y
= Immediately;
n
= after the IdF time
dAF Defrost delay after fast freezing:
(0min÷23h 50min) after a Fast Freezing cycle, the first defrost
will be delayed for this time.

temperature alarm condition after closing the door.
doA Open door alarm delay:
(0÷255 min) delay between the detection of the open door condition and
its alarm signalling: the flashing message “
dA
” is displayed.
nPS Pressure switch number:
(0
15) Number of activation of the pressure switch, during the “
did
”
interval, before signalling the alarm event (I2F= PAL).
