For each probe, after having specified the type, the minimum and
maximum values readable can be defined, as well as an "offset" to
compensate for any imprecisions in the value read (example: offset =
3% rH corresponds to a 3 percent increase in the humidity value read by
the probe). The "En. Al. " parameter enables the alarms corresponding to
probe faults. If a fault is detected for longer than the value of the "Delay"
parameter (seconds), the "main probe broken or disconnected" alarm will
be activated.
6.4.6 Pressure relief time setting
In the event of poor atomisation quality or dripping in the final
atomisation phase after a modulation period (Ton), the pressure relief
time can be adjusted, increasing it as much as necessary. The required
delay increases according to the length of the high pressure water line.
Increasing this time may mean the anti-dripping time also needs to be
adjusted, for two-zone systems. Always check correct operation of the
atomisation on and off phases in PWM modulation mode.

6.4.7 Anti-dripping time setting
For two-zone cabinets poor atomisation quality in the initial atomisation
phase after a modulation period (Toff ), the anti-dripping time can be
adjusted, increasing it as much as necessary. The required delay increases
according to the length of the high pressure water line and the setting of
the pressure relief parameter.

6.4.8 Anti-pressure return time setting
In the event of alarm ABA05: high bypass pressure, slightly increase
the anti-pressure return time to allow better pressure dissipation in the
cabinet.
