9.7.2 External proportional regulator with 0...10 V input
The humidity adjustment in proportional mode with 0...10 V input is done by setting:
• CFG = 1 or CFG = 6.
The outlet starts producing humidity in proportion to the input signal.

The proportional humidity function has a PWM type modulation which provides for a cycle time between two consecutive
activations of the humidity production output (parameter r3).
