zone and Dc08 for two-zone cabinets.

Possible settings:

Tab. 8.g
For each probe, after having specifi ed the type, the minimum and maximum
values readable can be defi ned, as well as an “off set” to compensate for any
imprecisions in the value read (example: off set = 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.
8.4.3 External signal setting

the single-zone and Dc09 for two-zone cabinets.

8.4.6 Pressure relief time setting
In the event of poor atomisation quality or dripping in the fi nal
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.

8.4.7 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.
