NOTE1: if none parameter is present in Pr1, after 3s the "noP"
message is displayed. Keep the keys pushed till the Pr2 message is
displayed.
NOTE2: the set value is stored even when the procedure is exited by
waiting the time-out to expire.
5.5.2 HOW TO MOVE A PARAMETER FROM THE HIDDEN
MENU TO THE FIRST LEVEL AND VICEVERSA.
Each parameter present in the HIDDEN MENU can be removed or put
into "THE FIRST LEVEL" (user level) by pressing SET +
In HIDDEN MENU when a parameter is present in First Level the
decimal point is on
.
5.6 HOW TO LOCK THE KEYBOARD
1. Keep pressed for more than 3 s the
2. The "POF" message will be displayed and the keyboard will be
locked. At this point it will be possible only to see the set point or
the MAX o Min temperature stored.
3. If a key is pressed more than 3s the "POF" message will be
displayed.
5.7 TO UNLOCK THE KEYBOARD
Keep pressed together for more than 3s the
"Pon" message will be displayed.
5.8 THE CONTINUOUS CYCLE
When defrost is not in progress, it can be activated by holding the "
key pressed for about 3 seconds. The compressor operates to
maintain the "ccS" set point for the time set through the "CCt"
parameter. The cycle can be terminated before the end of the set time
using the same activation key "
6. PARAMETERS
REGULATION
Hy Differential: (0,1 ÷ 25,5°C / 1÷45 °F) Intervention differential for
set point. Compressor Cut IN is Set Point + differential (Hy).
Compressor Cut OUT is when the temperature reaches the set
point.
LS Minimum set point: (-55°C÷SET/-67°F÷SET): Sets the
minimum value for the set point.
US Maximum set point: (SET÷150°C/ SET÷302°F). Set the
maximum value for set point.
Ot Thermostat probe calibration: (-12.0÷12.0°C; -21÷21°F)
allows to adjust possible offset of the thermostat probe.
P2P Evaporator probe presence: n= not present: the defrost stops
by time; y= present: the defrost stops by temperature.
OE Evaporator probe calibration: (-12.0÷12.0°C; -21÷21°F)
allows to adjust possible offset of the evaporator probe.
OdS Outputs activation delay at start up: (0÷255min) This function
is enabled at the initial start up of the instrument and inhibits any
output activation for the period of time set in the parameter.
AC Anti-short cycle delay: (0÷50 min) minimum interval between
the compressor stop and the following restart.
CCt Compressor ON time during continuous cycle: (0.0÷24.0h;
res. 10min) Allows to set the length of the continuous cycle:
compressor stays on without interruption for the CCt time. Can
be used, for instance, when the room is filled with new products.
CCS Set point for continuous cycle: (-55÷150°C) it sets the set
point used during the continuous cycle.
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.
COF Compressor OFF time with faulty probe: (0÷255 min) time
during which the compressor is OFF in case of faulty thermostat
probe. With COF=0 compressor is always active.

Manual GB
CH Type of action: CL = cooling; Ht = heating.
DISPLAY
CF Temperature measurement unit: °C=Celsius; °F=Fahrenheit.
WARNING: When the measurement unit is changed the SET
point and the values of some parameters have to be checked
and modified if necessary).
rES Resolution (for °C): (in = 1°C; dE = 0.1 °C) allows decimal
point display.
Lod Instrument display: (P1; P2, P3, P4, SET, dtr): it selects which
probe is displayed by the instrument: P1 = Thermostat probe;
P2 = Evaporator probe; P3 = Third probe(only for model with
this option enabled); P4 = Fourth probe, SET = set point; dtr =
percentage of visualization.
dLy Display delay: (0 ÷20.0m; risul. 10s) when the temperature
increases, the display is updated of 1 °C/1°F after this time.
DEFROST
tdF Defrost type: EL = electrical heater; in = hot gas.
dtE Defrost termination temperature: (-55÷50 °C/ -67÷122°F)
(Enabled only when EdF=Pb) sets the temperature measured by
the evaporator probe, which causes the end of defrost.
IdF Interval between defrost cycles: (0÷120h) Determines the
time interval between the beginning of two defrost cycles.
MdF (Maximum) length for defrost: (0÷255min) When P2P = n,
(not evaporator probe: timed defrost) it sets the defrost duration,
o o
o o "
when P2P = y (defrost end based on temperature) it sets the
maximum length for defrost.
dFd Temperature displayed during defrost: (rt = real temperature;
it = temperature at defrost start; SEt = set point; dEF = "dEF"
label)
dAd MAX display delay after defrost: (0÷255min). Sets the
maximum time between the end of defrost and the restarting of
the real room temperature display.
Fdt Drip time: (0÷120 min) time interval between reaching defrost
termination temperature and the restoring of the control's normal
operation. This time allows the evaporator to eliminate water
drops that might have formed due to defrost.
dPo First defrost after start-up: (y = immediately; n = after the IdF
time).
dAF Defrost delay after continuous cycle: (0÷24h) time interval
between the end of the fast freezing cycle and the following
defrost related to it.
FANS
FnC Fans operating mode:
C-n= runs with the compressor, OFF during defrost;
o-n = continuous mode, OFF during defrost;
C-Y = runs with the compressor, ON during defrost;
o-Y = continuous mode, ON during defrost.
Fnd Fans delay after defrost: (0÷255min) Interval between end of
defrost and evaporator fans start.
Fct Temperature differential avoiding short cycles of fans
(0÷50°C; Fct=0 function disabled). If the difference of
temperature between the evaporator and the room probes is
more than the value of the Fct parameter, the fans are switched
on.
FSt Fans stop temperature: (-55÷50°C/-67÷122°F) setting of
temperature, detected by evaporator probe, above which fans
are always OFF.
Fon Fan ON time: (0÷15 min) with Fnc = C_n or C_y, (fan activated
in parallel with compressor). it sets the evaporator fan ON
cycling time when the compressor is off. With Fon =0 and FoF ≠
0 the fan are always off, with Fon=0 and FoF =0 the fan are
always off.
