LIMIT PROBE
In the following graphics, the first represents the limitation of the
maximum production with a temperature limit probe or an activation
signal from the IEC ventilator. The second graphic, on the other hand,
represents the case in which the limit probe is a humidity probe or an
opening signal from the recirculation air lock.

7.3 Humidifi Evaporative Cooling
The optiMist humidifier provides the ability to configure the outlet
humidity control and the indirect evaporative cooling contribution
control at the same time.
ATTENTION: the operation of the two zones is mutually exclusive;
the two zones, therefore, will never work at the same time.
Selecting the active zone will depend upon:
a) the priority assigned by digital input ID4 (closed contact for I.E.C.,
open contact for Humidification) [see section 3.x];
b) the current request for humidity/cooling.
Once the priority is selected, the system will evaluate if the priority zone
will be in request, otherwise it will satisfy the request from the other zone.
The following examples shows the case where the priority is set for
indirect evaporative cooling, with step 1 dedicated to humidification and
step 2 to indirect cooling.
