6.2 Controllers with built-in driver
Some specific CAREL controllers for showcases and cold rooms include the hardware and software for the
management of electronic valves; these are programmed in different ways.

It is obvious that these controllers do not require a LAN connection to the driver, as this is built into the controller.
The driver user interface, both software that hardware, is part of the controller user interface.
Finally, it should be noted that for applications with lower cooling capacities, the use of an on-off solenoid valve
is recommended, rather than the battery module, considering the lower cost of the valves compared to the
batteries.
7. Control devices: basic parameter settings
To be able to start control, some fundamental parameters need to be set.
• Refrigerant
• Model of valve
• Minimum value pressure of the pressure transducer installed (barg)
• Maximum pressure value of the pressure transducer installed (barg)
• Battery module fitted (where available)
All the other parameters can be left at the default values, and configured at a later stage.
Nonetheless, it is suggested to read the following paragraphs and set the recommended parameters for the different
applications (paragraph 8.3).
