PROPORTIONAL mode with 0-10Vdc reference signal:
This kind of functioning allows steam production proportionally to reference signal 0-10V.
Example: a 6V reference signal will lead humidifier to produce 60% of steam referring to
software variable Pr. So if Pr= 70% will be 42%. To set the second level variable S9=2 and
make a bridge between terminal block 11 and 12, connect 0-10V reference signal to terminals
13 and 14, +V to terminal 13, GND to terminal 14.

PROPORTIONAL mode with 4-20mA humidity probe:
This kind of functioning allows steam production in proportional mode, humidifier will regulate
automatically the production of steam as per ambient request. Enabling is provided by a 420mA humidity probe that regulates steam production, also allowing visualization of ambient
relative humidity, directly on humidifier display. To set the second level variable S9=1 and
make a bridge between terminal block 10 and 11, connect 4-20mA humidity probe signal to
terminals 8 and 9, signal RH to terminal 9, +V to terminal 8.

Steam production request
The proportional band Bp is the percentage value of humidity near to the set point, inside this
value the humidifier works in proportional mode. Example: if the proportional band is set on
default value 10% (-5% / +5% set point value) and the humidity is set to 50%, under 45% the
humidifier will works to 100% of steam production; over 55% of humidity the humidifier will
not produce steam. Between 45% and 55% the humidifier will adjust the steam production
optimally.
