Each zone can be associated with a Dehumidifier, either for dehumidification or integration function, from the Configuration Zone/1 sub page:
...
If the zone is linked to a Temperature and Humidity Sensor (see ANALOG AND DIGITAL INPUT MULTIPLEXER) and if the zone is in Comfort or Economy mode (so in the Status column of the Zone Page is Comfort or Economy), the system compares the humidity measured in the zone with the humidity set point set via the Set Relative Humidity parameter in the Zones Parameters sub page: if the measured humidity is higher than the set point, the dehumidifier corresponding to the zone is activated.
Note
Zone temperature control logic is independent from the humidity control logic: a zone can be fulfilled in temperature, but not in humidity. In this case, the main output of the zone will be off, but the associated dehumidifier will be on. The opposite is also true.
...
A dehumidifier can be associated with several zones: in this case the dehumidifier is activated if even only one of the associated zones requires its intervention.
Warning
Each zone has its own humidity set, so it is not necessary that the zone that starts the dehumidifier is the one with the highest humidity; if, for example:
...
The following is an illustrative example of dehumidifier operation and associated output activation.

Zone associate a deumidificatori SENZA sensore di Umidità
Anche una zona dotata di un sensore di sola temperatura (senza cioè misura dell'umidità) può essere associata ad un deumidificatore; in questo caso la zona non controlla il deumidificatore (cioè non ne comanda mai l'accensione), ma usa il deumidificatore come "tramite" per valutare la possibile formazione di condensa; per maggiori dettagli vedere https://setecna.atlassian.net/wiki/spaces/PUBDOCS/pages/3258778841.

Zones associated with dehumidifiers WHITOUT a humidity sensor
A zone equipped with a temperature-only sensor (that is without humidity measurement) can be associated with a dehumidifier; in this case, the zone does not control the dehumidifier (i.e., it never controls its ignition), but it uses the dehumidifier as a “vehicle” to assess the possible formation of condensation; for more details, see GESTIONE DELLA CONDENSA DEW POINT MANAGEMENT.
