1. Push and immediately release the SET key: the display will show the Set point value;
To change the Set value push the o or n arrows within 10s.
2.
3. To memorise the new set point value push the SET key again or wait 10s.
5.6 TO START A MANUAL DEFROST
1. Push the DEF key for more than 2 seconds and a manual defrost will start.
5.7 TO ENTER IN PARAMETERS LIST "PR1"
To enter the parameter list "Pr1" (user accessible parameters) operate as follows:
1. Enter the Programming mode by pressing the Set and DOWN key for
few seconds (
2. The instrument will show the first parameter present in "Pr1"
THE HIDDEN MENU
The hidden menu Includes all the parameters of the instrument.
HOW TO ENTER THE HIDDEN MENU
1. Enter the Programming mode by pressing the Set + n keys for 3s (

Installing and Operating Instructions
)
)
and start blinking).
and start blinking).
2. Released the keys, then push again the Set+n keys for more than 7s. The Pr2 label will be
displayed immediately followed from the HY parameter.
NOW YOU ARE IN THE HIDDEN MENU.
3. Select the required parameter.
4. Press the "SET" key to display its value
5. Use o or n to change its value.
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.
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.
5.8 HOW TO CHANGE THE PARAMETER VALUE
1. Enter the Programming mode.
2. Select the required parameter with o or n.
3. Press the "SET" key to display its value (
4. Use o or n to change its value.
5. Press "SET" to store the new value and move to the following parameter.
To exit: Press SET + UP or wait 15s without pressing a key.
NOTE: the new programming is stored even when the procedure is exited by waiting the time-out.
5.9 HOW TO LOCK THE KEYBOARD
Keep the o and n keys pressed together for more than 3 s the o and n keys.
1.
2.
The "POF" message will be displayed and the keyboard is locked. At this point it is
only possible the viewing of the set point or the MAX o Min temperature stored and
to switch ON and OFF the light, the auxiliary output and the instrument.
TO UNLOCK THE KEYBOARD
Keep the o and n keys pressed together for more than 3s.
5.10 ON/OFF FUNCTION (STAND BY)
By pushing the ON/OFF key, the instrument shows "OFF" for 5 sec. and the ON/OFF LED
is switched ON.
During the OFF status, all the relays are switched OFF and the regulations are stopped; if
a monitoring system is connected, it does not record the instrument data and alarms.
When the instrument is in stand by the keyboard displays "oFF".
N.B. During the OFF status the Light and AUX buttons are active.
5.11 TO SEE THE PROBE VALUES
1.
Enter in "Pr1" level.
2. Parameters "dP1", "dP2" "dP3" and "dP4" display the value of probes 1, 2, 3 and 4.

6. Parameter List

REGULATION
Hy Differential: (0,1÷25,5°C; 1÷45°F): Intervention differential for set point, always positive.
Compressor Cut IN is Set Point Plus Differential (Hy). Compressor Cut OUT is when the
temperature reaches the set point.
LS Minimum set point limit: (-50,0°C
the set point.
÷
US Maximum set point limit: (SET 110°C; SET÷230°F) Set the maximum acceptable value for set
point.
PROBE INPUTS
Ot Thermostat probe calibration (term. 1-2): ( (-12.0
offset of the thermostat probe.
P2P Evaporator probe presence (term. 2-3):
n= not present: the defrost stops only by time; y= present: the defrost stops by temperature and
time.
OE Evaporator probe calibration: (-12.0
evaporator probe.
P3P Third probe presence (term. 4-5): n= not present; y= present.
÷
O3 Third probe calibration: (-12.0 12.0°C/ -21
probe.
P4P Fourth probe presence (term. 5-6): n= not present; y= present.
O4 Fourth probe calibration: (-12.0
fourth probe.
OdS Outputs activation delay at start up: (0÷255 min) 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.
(AUX and Light can work)
AC Anti-short cycle delay: (0÷30 min) interval between the compressor stop and the following
restart.
AC1 Time delay between turning on compressor 2 : (0÷255 sec) allows to set the delay between
turning on the first and the second compressor. It's used with oA3 = cP2.
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 Thermostat override: (0min ÷23h 50min) allows to set the length of the continuous cycle. 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.
