Universal-XR 8/17 UXR01212015_REV1.4mm

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.

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.

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 Set Point, HY, LS, US, ALU, ALL, dtE, FSt,

ot & oE, as they can be effected.

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.

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;
