Installation and Operating Instructions
P3P
Third probe presence (probe named Evap.2 on the label):
0= n
= not present, the third input (
the one signed with label “D.I.
/ Pb3”) Input operates as digital input;
1= Y
= present, the third input (
the one signed with label “D.I.
/ Pb3”) Input operates as third probe.
O3
Third probe calibration:
(-12.0 to 12.0°C or -21 to 21°F) adjustment for third probe offset.
RES
Display resolution (Only available in Celsius):
0=
dE
= with decimal point;
1= in
= without decimal point.
CF
Temperature measurement unit:
0=
°C
= Celsius;
1= °F
= Fahrenheit.
Warning:
If you alter the setting of parameter
rES
( decimal point on/off ) re-check the settings of all temperature related parameters

LOD
Probe for Display:
0= P1
= Thermostat probe;
1= P2
= Evaporator probe;
2= P3
= Third probe;
3= sEt
= DISPLAY ONLY SHOWS THE SET-POINT. THE ACTUAL TEMPERATURE CAN BE SEEN BY PRESSING THE SET BUTTON.
DLY
Display delay:
(0 ÷ 20min0sec; resolution 10 sec) when the temperature increases, the display is updated of 1°C or 1°F after this time.
CH
Type of action:
0
= Cl = cooling;
1=
Ht = heating.
CON
Compressor ON time with faulty probe:
(0 to 255min) If there is a P1 probe failure the controller will automatically cycle the compressor on/off according to
Con
&
CoF
to
maintain basic cooling.
Con
is the compressor “ON” time.
COF
Compressor OFF time with faulty probe:
(0 to 255min) If there is a P1 probe failure the controller will automatically cycle the compressor on/off according to
Con
&
CoF
to
maintain basic cooling.
CoF
is the compressor “OFF” time.
TBA
Alarm muting:
0=
n
= Alarm relay remains active when alarm buzzer is muted;
1=
Y = Alarm relay is cancelled when alarm buzzer is muted.
I2F
Second digital input operating mode:
configures the second digital input function:
0
= Starts a defrost;
1
= Input from a door switch (see parameter
odC
);
2
= Activates the auxiliary relay;
3
= Starts Energy Saving (Control Point becomes Set Point +/- value in
HES
);
4
= Remote On/OFF (puts the controller into standby);
5
= Generic external alarm (normal regulation continues);
6
= Serious external alarm (regulation is stopped).
I2P
Configurable second digital input polarity:
0
= the digital input is activated by closing the circuit;
1
= the digital input is activated by opening the circuit.
DI2
Time interval/delay for digital input 2 alarm:
(0 to 255min) it defines the time delay between the detection and the subsequent signalling of the alarm.
ODC
Compressor and fan status when open door:
0= no
= normal;
1= FAn
= Fan OFF;
2= CPr
= Compressor OFF;
3= F_C
= Compressor and fan OFF.
OAA
Defrost relay configuration: Only on tC=7
0= Alr
= Alarm;
1= db
= Dead Band;
2= AUS
= Auxiliary;
3= Cp2
= Second compressor output;
4= LIG
= Light output;
5= dF2
= Second defrost output.
OAB
Auxiliary relay configuration:
1= Alr
= Alarm;
2= db
= Dead Band;
3= AUS
= Auxiliary;
4= Cp2
= Second compressor output;
5= LIG
= Light output;
6= dF2
= Second defrost output.
AOP
Alarm relay polarity:
0= CL
= contact [13
–
14] closed with alarm;
1= oP
= contact [13
–
14] open with alarm.
DOT
Temperature alarm exclusion with door open:
0 to 255min.
