6.7
THE CONTINUOUS CYCLE
It can be activated by holding the “
o
” 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 “
o
” for 3 seconds.
6.8
THE ON/OFF FUNCTION
With “onF = oFF”, pushing the ON/OFF 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.

PARAMETERS
REGULATION
Hy Differential: (0,1 ÷ 25,5°C / 1÷255 °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: (- 50°C÷SET/-58°F÷SET): Sets the minimum value for the set point.
US Maximum set point: (SET÷110°C/ SET÷230°F). Set the maximum value for set point.
Ot Thermostat probe calibration: (-12.0÷12.0°C; -120÷120°F) allows to adjust possible offset of
the thermostat probe.
P2P Second probe presence: n= not present; y= present.
OE Second probe calibration: (-12.0÷12.0°C; -120÷120°F). allows to adjust possible offset of the
second probe.
P3P Third probe presence (P3): n= not present:, the terminals 13-14 operate as digital input.; y=
present:, the terminals 13-14 operate as third probe.
O3 Third probe calibration (P3): (-12.0÷12.0°C; -120÷120°F). allows to adjust possible offset of
the third probe.
P4P Fourth probe presence: (n = Not present; y = present).
o4 Fourth probe calibration: (-12.0
12.0°C) allows to adjust possible offset of the fourth 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.
AC1 2
nd
compressor delay at start up (0÷255s) Used only if oA3 = cP2 Time interval between the
switching on of the first compressor and the second one.
rtr Percentage of the second and first probe for regulation (0÷100; 100 = P1, 0 = P2 ): it
allows to set the regulation according to the percentage of the first and second probe, as for the
following formula (rtr(P1-P2)/100 + P2).
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: (-50÷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.
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 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 = Second probe; P3 = Third probe(only for model with
this option enabled); P4 = Fourth probe, SET = set point; dtr = percentage of visualization.
rEd X- REP display (optional): (P1; P2, P3, P4, SET, dtr): it selects which probe is displayed by
X- REP: P1 = Thermostat probe; P2 = Second 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.
dtr Percentage of the second and first probe for visualization when Lod = dtr (0÷100; 100 =
P1, 0 = P2 ): if Lod = dtr it allows to set the visualization according to the percentage of the
first and second probe, as for the following formula (dtr(P1-P2)/100 + P2).
AUXILIARY THERMOSTAT CONFIGURATION (terms. 1-3) – OA3 = AUS
ACH Kind of regulation for auxiliary relay: Ht = heating; CL = cooling
SAA Set Point for auxiliary relay: (-50,0÷110,0°C; -58÷230°F) it defines the room temperature set
point to switch auxiliary relay.
SHy Differential for auxiliary output: (0,1 ÷ 25,5°C / 1÷255 °F) Intervention differential for
auxiliary output set point.
With ACH = cL AUX Cut in is SAA + SHy; . AUX Cut out is SAA
With ACH = Ht AUX Cut in is SAA - SHy; . AUX Cut out is SAA
ArP Probe selection for auxiliary: nP = no probe, the auxiliary relay is switched only by button; P1
= Probe 1 (Thermostat probe); P2 = Probe 2 (second probe); P3 = Probe 3 (display probe); P4
= Probe 4 fourth probe.
Sdd Auxiliary relay off during defrost: n = the auxiliary relay operates during defrost.
y
=
the auxiliary relay is switched off during defrost.
ALARMS
ALP Probe selection for alarm: nP = no probe, the temperature alarms are disabled; P1 = Probe 1
(Thermostat probe); P2 = Probe 2 (second probe); P3 = Probe 3 (display probe); P4 = Fourth
probe.
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: (SET÷110°C; SET÷230°F) when this temperature is reached
the alarm is enabled, after the “ALd” delay time.
