6.8 THE CONTINUOUS CYCLE
When defrost is not in progress, it can be activated by holding the UP key pressed for about 3 sec.
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 UP for 3 sec.
6.9 THE ON/OFF FUNCTION
With onF=oFF, pushing the ONOFF key, the instrument is switched off. The "OFF"
message is displayed. In this configuration, the regulation is disabled.
To switch the instrument on, push again the ON/OFF key.
WARNING: Loads connected to the normally closed contacts of the relays are always supplied
and under voltage, even if the instrument is in stand by mode.
7. 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.
DISPLAY
CF Temperature measurement unit: °C=Celsius; °F=Fahrenheit. WARNING: When the
measurement unit is changed the SET point and the values of the parameters Hy, LS, US, Ot,
ALU and ALL 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; resul. 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, when P2P = y (defrost end based on temperature) it sets the
maximum length for defrost.
dSd Start defrost delay: ( 0÷255min) This is useful when different defrost start times are necessary
to avoid overloading the plant.
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÷255 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.
Fno Fans delay after compressor start: (0÷255min) Interval between compressor start and
evaporator fans start.
Fct Temperature differential avoiding short cycles of fans (0÷59°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/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.
FoF Fan OFF time: (0÷15 min) with Fnc = C_n or C_y, (fan activated in parallel with compressor). it
sets the evaporator fan off 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.
FSU Fan working mode:
Std: standard working, according to Fnc
FoF: by pushing the DOWN key for 3s the fan are enabled/disabled.
Fon: with Fnc= C-n or C-y by pushing the DOWN key for 3s the fan passes from in parallel to
the compressor to in continuous mode.
ALARMS
ALC Temperature alarms configuration: (Ab; rE)
Ab= absolute temperature: alarm temperature is given by the ALL or ALU values. rE =
temperature alarms are referred to the set point. Temperature alarm is enabled when the
temperature exceeds the "SET+ALU" or "SET-ALL" values.
ALU MAXIMUM temperature alarm: (ALL÷150°C) when this temperature is reached the alarm is
enabled, after the "ALd" delay time.
ALL Minimum temperature alarm: (-55.0 °C÷ALU) when this temperature is reached the alarm is
enabled, after the "ALd" delay time.
ALd Temperature alarm delay: (0÷255 min) time interval between the detection of an alarm
condition and alarm signalling.
dAO Exclusion of temperature alarm at start-up: (from 0.0 min to 24h) time interval between the
detection of the temperature alarm condition after instrument power on and alarm signalling.
DIGITAL INPUT
i1P Digital input polarity (13-14): oP: the digital input is activated by opening the contact; CL: the
digital input is activated by closing the contact.
i1F Digital input configuration (13-14): EAL= external alarm: "EA" message is displayed; bAL=
serious alarm "CA" message is displayed. PAL= pressure switch alarm, "CA" message is
displayed; dor= door switch function; dEF= activation of a defrost cycle; AUS=not enabled; Htr=
kind of action inversion (cooling – heating); FAn= not set it; ES= Energy saving; onF = to switch
the controller off.
did (0÷255 min) with i1F= EAL or i1F = bAL digital input alarm delay (13-14): delay between the
detection of the external alarm condition and its signalling.
with i1F= dor: door open signalling delay
