INSTRUMENT PROGRAMMING
Operation parameters, completely modi able from front keypad. Access to these is protected by a password that prevents random changes or modi cations by
unauthorised persons.
Accessing parameters (confi guration):
1. press the PRG and SET buttons together for more than 5 seconds and the display will show "00", password required;
2. use the buttons or to scroll the numbers until displaying "11" (Password for accessing parameters);
3. con rming with SET, the rst modi able parameter will appear on the display.
Modifying parameters
After displaying the parameter, proceed as follows:
1. use the buttons or to scroll the parameters to the one to be modi ed. Scrolling is accompanied by lighting up of an icon on the display, representing the
parameter category. Alternatively, press the PRG button to display a menu of the categories or parameters for quickly accessing the family of parameters to be
changed;
2. scroll the menu with the buttons and and the codes of the various parameter categories (see "Summary of operation parameters") are displayed, together
with lighting up of the corresponding icon (if present);
3. on accessing the category, press SET to go straight to the rst parameter of the selected category (if no parameter is visible, pressing the SET button will
have no e ect);
4. it is possible to continue consulting the parameters or return to the categories menu with the PRG button;
5. press SET to display the value associated with the parameter;
6. increase or decrease the value respectively with the buttons and ;
7. press SET to temporarily save the new value and return to the display of the parameter. Repeat the procedure from step 1 or step 2;
8. if the parameter has subparameters, press SET to display the rst subparameter;
9. press the buttons or to view all the subparameters;
10. press SET to display the associated value;
11. increase or decrease the value respectively with the buttons or ;
12. press SET to temporarily save the new value and return to the display of the subparameter code;
13. press PRG to return to the display of the parent parameter.
Saving new values assigned to parameters
To permanently save the values of the modi ed parameters, press the PRG button for more than 5 seconds, thus exiting the parameter modi cation proce-
dure. It is possible to cancel all the parameter modi cations, temporarily stored in RAM, and return to "normal operation" by not pressing any button for 60 seconds,
thus allowing the parameter modi cation session to expire for TIMEOUT.
Attention: If the modi cation session expires for timeout, the parameters will not be not restored.
If the power to the instrument is switched o before pressing the PRG button, all changes made to the parameters and temporarily saved will be lost.

In case of faulty thermostatting probe, the display shows the message rE alternating with E0 (compartment probe S1). The appliance still
works and compressor activation and/or deactivation is time managed (15 min. ON and 15 min. OFF). The alarm condition is automatically reset as soon as compartment probe operation is restored.
In case of faulty room probe, the display shows the message E1 (room
probe S2). The alarm condition is automatically reset as soon as compartment probe operation is restored.
The service alarm signalling icon fl ashes whereas the controller buzzer
is deactivated
The service alarm signalling icon fl ashes whereas the controller buz-
zer is deactivated. In case of faulty condenser probe (if installed on
the machine), the display alternately shows the message SEr/E2. The
alarm condition is automatically reset as soon as compartment probe
operation is restored.
Clean alarm: when the condenser is very dirty on the display will
appear the label
CLn; this alarm dosen’t stop the cycle but only
advises the customer to clean the condenser. The
CLn alarm
appears only after 90 days to work of compressor and when the
temperature of the condenser and ambient is over to delta of the
parameter
ACS
The alarm disapears when the temperature decrease from parameter
ACd.( differential) or pressing the button Prg.
With the LED lamp disconnected, the display will show the message
ce in sequence of temperature.
This happens when the lamp is disconnected or damaged.
In case of no lamp connection, the controller does not diagnose any fault.

To manually activate a defrost cycle it is necessary to keep the temperature decrease button pressed for at least 3 seconds.
The display shows the message dFb/defrost
start for a few seconds
and the icon signalling activation of the defrost cycle lights up.
Defrost can be manually stopped by pressing the DEF/decrease temperature button again for at least 3 seconds. The display shows the
message dFE/defrost
end.
Defrost in the range models is carried out following the algorithm values: 1) parameter dF0, associating the actual hours of compressor
operation, 2) parameter dF1, number of door openings, where parameter dF0 must be reduced ,3)parameter dF2, minutes to be add to
parameter dF1 from subtracted to parameter dF0,to anticipate defrost .
Parameter dl remains active if these values are not respected.
In case of activation of continuous cycle, by pressing the temperature
decrease button for more than 5 seconds the display will show the
message ccb, at the same time as the temperature the message tc
will appear, meaning that “turbo cooling” has been activated. The cycle
will end for time, by parameter CC, or for temperature by parameter
AL, or by pressing the button again.
The humidity value is activated by pressing the corresponding button.
Three modes can be activated: low, medium, high % .F0= 3
The function activates the evaporator fans following the logic of low,
medium and high humidity % to be obtained in the compartment.

Algoritmo defrost/defrost algorithm Ecostore ONLY
Defrost
Defrost management has in principle the same features of the current FW: however, as the evaporator probe is
not present, defrost will be managed by counting working hours of the compressor and will end for timeout.
A programmed defrost will be done every defined number (parameter dF0) of working hours.
In addition, the algorithm will count the number of openings of the door as well. The aim is to anticipate of a
number of minutes (dF2) the programmed defrost with reference to the total number of openings of the d
oor.
Every time the programmed defrost is done, the total on-time hours of compressor and the number of door
openings will be reset. Proper parameters will be employed in order to manage this algorithm.
In order to do this, consider flux diagram of Figure 3.4. For instance, t_on_cmpr is the variable counting on-time
hours of compressor starting from last defrost, whereas n_open_door is the number of openings of the door.
t_on_cmpr is reset after each defrost, while n_open_door is reset every time it reaches dF1 value.
