MODIFICATION OF THE MANUFACTURER’S 

PARAMETERS

The Manufacturer level allows the configuration of all controller 

parameters, and therefore, in addition to the Assistance 

parameters, the parameters corresponding to the management of 

alarms, probes and valve configuration. 

Procedure:

1. Press Esc one or more times to go to the standard display.

2. Select the A or B driver for which you want to change the 

parameters.

3. Press Prg: the display shows a screen asking for the 

PASSWORD;

4. Press ENTER and enter the password for the Manufacturer 

level: 66, starting from the rightmost digit and confirm each 

digit with ENTER.

5. If the value entered is correct, the list of parameter categories 

appears:

• Configuration

• Probes

• Control

• Special

• Alarm configuration

• Valve

6. Press UP/DOWN to select the category and ENTER to access 

the first parameter of the category.

7. Press UP/DOWN to select the parameter to be changed and 

ENTER to move to the parameter value.

8. Press UP/DOWN to modify the value.

9. Press ENTER to save the new parameter value.

10.  Repeat steps 7, 8 and 9 to modify the other parameters.

11.  Press ESc to exit the Manufacturer parameter modification 

procedure.

NOTES:

- The entry at the Manufacturer level allows modification of 

all controller parameters.

- If an out-of-range value is entered during the configuration 

of a parameter, it is not accepted and the parameter 

returns to the value before the modification after a 

short time.

- If no key is pressed, the display automatically returns to the 

standard display after 5 minutes.

NETWORK ADDRESS 

The network address assigns the controller an address for serial 

connection to a supervisory system via RS485 and to a pCO 

controller via pLAN, tLAN, Modbus®. It is a common parameter for 

both driver A and B.

-

In the case of network connection of the RS485/Modbus® models, 

it is also necessary to set the communication speed in bits per 

second, by means of the parameter “Network settings.

REFRIGERANT

The type of refrigerant is essential for the calculation of superheat. 

It is also used to calculate the evaporating and condensing 

temperature from the pressure probe measurement.

VALVE

By setting the valve type, all the control parameters are automatically 

defined based on the construction data of each model. In the 

manufacturer’s programming mode it will then be possible to fully 

customize the control parameters in case the valve used is not 

present in the predefined list. In such a case, the controller will 

indicate the modification by marking the valve type as “Custom”.

- If no key is pressed, the display automatically returns to the 

standard display after 5 minutes.

- To set a negative value, position with Enter on the leftmost 

digit and press Up/Down.

NOTES:

-  The  configuration  of  two  CAREL  ExV  valves  connected 

together  must  be  selected  whenever  two  CAREL 

ExV valves are to be connected to the same terminal, 

to achieve parallel or complementary operation;

-  As indicated above, regulation is only possible with CAREL 

ExV valves;

-  Not all CAREL valves can be connected.
