6.
Press “
SET
” to store the new value and move to the following parameter.
To exit
: Press
SET +
o
or wait 15s without pressing a key.
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.
6.6.2 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 +
n
”
.
In HIDDEN MENU when a parameter is present in First Level the decimal point is on.
6.7
HOW TO LOCK THE KEYBOARD
1.
Keep pressed for more than 3 s the
UP
+
DOWN
keys.
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.
6.8
TO UNLOCK THE KEYBOARD
Keep pressed together for more than 3s the
o
and
n
keys, till the
“Pon”
message will be
displayed.
6.9
THE CONTINUOUS CYCLE
When defrost is not in progress, 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.
6.10
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
rtc Real time clock menu (only for controller with RTC):
to set the time and date and defrost
start time.
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 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; -120÷120°F). allows to adjust possible offset of
the evaporator 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.
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.
