POWER OFF

When the instruments is switched offthe display shows the label OFF and all internal relays are disabled (not energized)

POWER ON

When the controller is switched on a special procedure tests the display and the keypad. The display is completely ON for 2 seconds

Three segments “---“ on the display are visualized for 2 seconds and then the controller becomes operative

Compressor icons flashesand the compressor activation is delayed by safety times

To display or to set the temperature, proceeds as follows:

Keep SET button pressed for more than 1 second. The instruments displays the temperature value

SET CAVITY TEMPERATURE

Increase or decrease the set point using UP/DOWN buttons, until reaching the desired value

Press SET button again to confirm the new value

Press Prg/mute button more than 5 seconds the instruments shows the code of the first adjustable parameter (type “F”) – if an alarm is active, pressing this button, the buzzer is muted first.

FREQUENTLY USE PARAMETER LIST: St, rd, rt, rH, rL, dI, dt1, dt2, dP1, dP2, dd, d8, d/1, d/2, AL, AH, Ad, F1, Fd

FREQUENT USE PARAMETER (TYPE F)

CONFIGURATION Access to the configuration parameters is protected by password that PARAMETER avoid unwanted modifications or access by unauthorized personel. (TYPE C) Proceeds as follows:

1. Press Prg/Mute and Set buttons together for more than 3

seconds; display shows a flashing numerical code “0” that indicates the password prompt

2. Press UP button to set the password – CAREL thermoregulators are

provided with password set to 11 (the code of the password allows access to the configuration parameters)

mode and scroll up/down the operating parameters list /2

3. Confirm by pressing the Set button to enter in the programming

4. Display shows the code of the first adjustable type “C” parameter

MANUAL DEFROST

Manual defrost is activated or deactivated if DEF/DOWN button is keep pressed more than 5 seconds.

When defrost starts display shows dFb (defrost begining)

Defrost’s warning icon is ON when defrost is active

Defrost can be interrupted simply by pressing again the DEF/DOWN button more than 5 seconds. Display shows the message dFE(defrost End)

After having displayed the first operating parameter, either type C or type F, it is necessary to procedes as follows:

1. Press UP/DOWNbutton until reaching the parameter to be

modified. When scrolling the list, an icon appears on the display that indicates the category the parameter belongs to

2. Press SET button to display the parameter’s value

MODIFYING THE PARAMETERS

3. Increase or decrease its value using UP/DOWN button

4. Press again SET button to temporarily save the new value, closing

the parameter adjustment and return to the display of the parameter code

Repeat the operations from point 1 to 4

STORING THE NEW ASSIGNED VALUES

To definitively store the new values of the modified parameters, procede as follows:

1. Press the Prg/mute button more than 5 seconds

2. Display shows the label Pro

The controller step out the parameter setting procedure and the display shows current temperature value.

RESET ANY

MODIFICATIONS

All modifications made to the parameters, temporarily stored into the internally memory of the controller, can be cancelled and normal operation resumed by not pressing any button for 60 second, thus allowing the parameter setting session to expire due to timeout

HOW TO CHECK CAVITY PROBE TEMPERATURE

To check current temperature measured by a single installed probe, proceeds as follow:

1. refers to the previous step how to get in the configuration

parameter session - type C parameter

2. scroll the configuration parameter list, by using UP/DOWN

buttons, until display shows the parameter /C1 (calibration or offset for cavity probe) 3. press SET button

4. display shows the probe calibration value, used to correct the

temperature measured by the probe by means of an offset

BE CAREFUL ⇒ DO NOTADJUST THE CALIBRATION VALUE

5. Press again SET button

6. display shows the current temperature value measured by the

probe

7. press SET button to return to display of the parameter code /C1 Current evaporator probe temperature is available by means of the parameter /C2 (calibration or offset for evaporator probe)

To check temperature value proceeds as previously indicated from step 1 to step 2, considering the configuration parameter /C2

HOW TO CHECK EVAPORATOR TEMPERATURE

HOW TO CHECK CONDENSER TEMPERATURE

If the condenser probe is installed it is possible to check condenser temperature by means of the parameter /C3 (calibration or offset for condenser probe)

To check temperature value proceeds as previously indicated from step 1 to step 2, considering the configuration parameter /C3

SERVICE ALLARMS AND SIGNALS SERVICE ALARMS

SERVICE ALARMS DUE TO MALFUNCTIONING OR FAILURE PRODUCE A WARNING SIGNALS ON THE DISPLAY BY MEAN OF THE SERVICE ICON

CAVITY PROBE FAULT

In case of cavity probe faulty or malfunctioning display shows the error signal rE and E0 (cavity probe S1 fault) alternately

The appliance works however and compressor starts are controlled by time (15 mins is ON and 15 mins is OFF) until the fault is resolved.This alarm signal is automatically restored when the faulty erased and the probe replaced

During this time interval the service alarm icon flashes on display and an acoustic signal is ENABLED

In case of evaporator probe faulty or malfunctioning display shows an error signal E1 (evaporator probe S2 fault).

This alarm signalis automatically restored when the faulty erased and the probe replaced

EVAPORATOR PROBE FAULTY

During this time interval the service alarm icon flashes on display. Acoustic signal is DISABLED

CONDENSER In case of condenser probe faulty or malfunctioning display shows the PROBE FAULTY error signal SEr and E2 (condenser probe S3 fault) alternately (WHEN INSTALLED ON BOARD)

This alarm signalis automatically restored when the faulty erased and the probe replaced

During this time interval the service alarm icon flashes on display. Acoustic signal is DISABLED

If a probe is set as the condenser probe, the condenser temperature can be monitored to signal the high temperature alarm, due to obstruction or fouling

In this case a warning signal is visualized and display shows the error signal CLn and the temperature measured by the condenser probe alternately

CLEAN ALARM

Service alarm icon is flashing and the acoustic signal DISABLED

The clean alarm is reset to zero by pressing the Prg/mute button and the service alarm icon cancelled on display

TEMPERATURE ALARMS AND SIGNALS TEMPERATURE ALARMS

HIGH OR LOW TEMPERATURE ALARMS DUE TO MALFUNCTIONING OR COMPONENTS FAILURE PRODUCE A WARNING SIGNALS ON THE DISPLAY BY MEAN OF THE ALARM ICON.

LOW

TEMPERATURE ALARM

In case of low cavity temperature, referred to the cavity probe, the display shows a flashing error code LO.

Temperature alarm icon is flashing and the acoustic signal ACTIVE.

This alarm is automatically reset when cavity temperature increase over the minimum temperature threshold, depending from the parameter AL

HIGH

TEMPERATURE ALARM

In case of high cavity temperature, referred to the cavity probe, the display shows a flashing error code HI.

Temperature alarm icon is flashing and the acoustic signal ACTIVE.

This alarm is automatically reset when cavity temperature decreaseunder the maximum temperature threshold, depending from the parameter AH

In case of condenser fan faulty ormalfunctioning display shows a flashing error code SEr

Temperature alarm icon is flashing and the acoustic signal ACTIVE

Pressing Prg/mute button the buzzer is DISABLED but the alarm signal is still active and shown on the display
