1. INTRODUCTION
EVD 4 is an evolved PID controller complete with driver for stepper motors specially designed for the ma-
nagement of electronic expansion valves in refrigerant circuits. It features sophisticated control functions
and can be used in many operating confi gurations in refrigeration and air-conditioning systems, such as:
- PID control of superheat with protection and safety compensation functions;
- PID control on one measurement (pressure or temperature);
- positioner for electronic expansion valves controlled by 4 to 20 mA or 0 to 10 Volt signal.
The device is confi gured and the address set via serial interface and the user interface software is stored
in non-volatile memory.
