6.2 Scheduler
The Scheduler menu enables operation based on time bands.
Index Description Parameter
B01
Scheduler Enable time bands
Default: time bands disabled
To configure the humidifier operating time bands for a specific day (24h),
use screen B02 (visible only if the scheduler is enabled). A time band can
be set with production disabled (OFF) or enabled (ON). Setting the ON
time band, the unit uses the main set point configured on screen Qb01.
Index Description Parameter
B02
Scheduler Define daily and weekly time bands
Fig. 6.a
In the example shown here in Fig.7.a, the time band from 8.00 to 9.00 is
enabled for production. After 9.00, the humidifier will not be enabled.
unit of measure indication: symbol displayed Unit of measure

°F Degrees Fahrenheit
Once the time bands have been defined for one day, press to copy
the currently displayed bands (daily) to the next day. When the time
bands have been set, the display shows the symbol.
6.3 Proportional control to an external
signal (modulating operation)
Atomisation is proportional to the value of an external signal Y, (selectable
from the following options: 0 to 1 Vdc; 0 to 10 Vdc; 2 to 10 Vdc; 0 to 20 mA; 4
to 20 mA). The maximum production Pmax corresponds to the maximum
value of the external signal Y, and will be the humidifier’s rated production.
The activation hysteresis hy is not settable by the user.

6.4 Autonomous control with humidity
probes
When using a main humidity control probe and an optional limit
humidity probe, atomisation is related to the % rH reading made by the
relative humidity probe and increases as the value read deviates from the
set point St. Maximum production Pmax corresponds to the case where
the humidity value, read by the probe, is BP away (proportional band)
from the set point. The activation hysteresis hy is not settable by the user.
