Regulation device

A device for the regulation of devices which can be regulated with a 0-10 Vdc and/or PWM command, said device comprising:

• at least one power supply input;
• at least one regulation input adapted to receive external regulation signals;
• a potentiometer comprising a selector element, the potentiometer being configured to provide a manual voltage regulation;
• and
• at least one command output configured to output a command signal, for example of the 0-10 Vdc and/or PWM type, towards the devices to be regulated,
• wherein the device further comprises a switching element configured to cause a switching of said device between a first regulation mode, in which the command signal is generated by said device and is manually adjustable through the selector element of the potentiometer, and a second regulation mode, which allows a regulation of the devices to be regulated via the command signal from the command output based on an external device connectable to the regulation input, and
• wherein the device is configured to act as an emergency by-pass when an external signal provided through the regulation input is interrupted, wherein the potentiometer is arranged and configured to provide a command based on the regulation thereof when the above interruption occurs,
• the device further comprising means adapted to amplify an external dc command which comes from an external device via the regulation input, wherein the command output thereby outputs an amplified command.
