Zones are the basic element of the REG System and it can manage a maximum of 32 zones. Without Zone, Dehumidifiers, Circuits, and consequently Source cannot be activated.
The primary function of the Zone is to determine when to heat, cool and/or dehumidify a part of the system, based on one or more of the following information:
General States (determined by the Global Settings subsystem) such as Global System Activation and Current Season.
An associated Timetable, which determines the current Working Mode of the Zone, and therefore the operating times of the zone (see TIMETABLES).
A room probe/sensor, if present (which can be temperature only, temperature and humidity, or air quality).
An external dry contact, if present (for example a signal coming from an installed temperature thermostat, or from the limit switch contact of a zone valve).
By acting on the Zone parameters, it is possible to configure how to combine this information to determine the conditions under which the zone should activate.
In turn, the zone can activate other subsystems; it can activate:
A Circuit, when the zone is activated to heat and/or cool.
A Dehumidifier, when the zone detects that dehumidification is required.
Another Dehumidifier (which in most cases is the same as the previous point), when the zone detects that it is necessary to integrate the heating/cooling function.

Note
In a radiant system, each room of the system equipped with a sensor (temperature or temperature + humidity) is managed by a Zone.
In a system for mixed circuits management, a Zone is associated with each circuit to determine the activation conditions of the circuit itself.
Normally each temperature sensor corresponds to a zone, but exceptions may be possible:
In a bathroom, the same sensor can control both the radiant floor and a towel heater; in this case, we should configure TWO zones, which use the same sensor.
PHOTO TBD
In a mixed system, the same sensor can control the radiant floor in winter and a fan coil in summer; even in this case we should configure TWO zones, which are based on the same sensor.
A zone could NOT be associated with any sensor, for example:
In a bathroom the towel heater may be switched on at certain times, regardless of the sensor reading in the room.
A zone could be used to control the change of air: even in this case the switching on could be timed and not take any sensor into account (see CMV FUNCTION WITH TIMETABLE AND/OR VOC SENSOR).
Use of the zones in system for the control of Direct/Mixed circuits
In the system used for the control of Direct/Mixed circuits, the Zones take on a slightly different meaning from the standard one, as here the zones are not Environments/Locations, but to all intents and purposes take on the meaning of Circuits. In the following:
Zones are associated with Direct/Mixed Circuits
Zone Sensors are generally not used
An example is given below:
Typical case: Control of 1 Direct and 2 Mixed Circuits
The system controls the operation of a central thermic system and in particular there are three circuits:
Circuit 3 is of the Direct type with flow temperature set at 60 °C
Circuits 1 and 2 are of the Mixed type to control the heating of radiant surfaces, with flow temperature set at 24°C and 20°C respectively.
In this case the logic with which the system must be constructed is as follow:
3 Zones must be set up, each corresponding to a circuit.
A Circuit must be associated with each zone, every circuit must have a sensor to control the Flow Temperature (see SET POINT AND SENSORS SETTINGS of the Circuits).
As regards the activation of the zones (or rather, circuits), associate each one with its own timetable to determine the operating status and do not set zone sensor, so that if the timetable is active, the corresponding zone is automatically active.
It is possible to associate an activation/enabling signal (classic room Thermostat)
Associate to the direct circuit the operation of 1 water pump.
Associate to each one of mixed circuit the control of 1 water pump and 1 mixing valve (see WATER PUMPS AND MIXING VALVES SETTINGS)

Descrizione Zona
Ad ogni Zona è assegnata una Descrizione (vedere DESCRIPTIONS), cioè un breve testo (massimo 16 caratteri) che permetta di identificare agevolmente la funzione della Zona, impostabile nella Pagina Zone - Configurazione Zona /1.
Solitamente la descrizione viene associata ad:
un ambiente (Cucina, Salotto, Camera, ecc..)
un Circuito (Miscelato 1, Diretto, Alta Temperatura, ecc..)
un'utenza particolare (Scaldasalviette, Integrazione, Termoarredo, ecc..)
È inoltre possibile non associare nessuna descrizione, in questo modo la zona non verrà visualizzata sul Display REG-TFT o REG-DOT-B; solitamente questa operazione viene effettuata per tutte quelle zone che non si desidera far vedere all'utente finale (ad esempio zone utilizzate come integrazioni negli impianti di raffrescamento).
Le zone senza descrizione non sono visualizzate neanche in telegestione!
Attenzione
Su impianti molto complessi non associare descrizioni alle Zone potrebbe essere fonte di fraintendimenti e complicazioni durante l’assistenze. Quindi sempre meglio assegnare un nome.
Poi se non si vuole visualizzare alcune zone sui display o in telegestione allora dalla sottopagina Configurazione Zona/3:
come per gli orologi, è possibile spuntando uno dei due quadratini bianchi sotto Nascondi su TFT/DOT nascondere la zona sul display 1 o sul display 2 (ad esempio se il display 1 è nella zona giorno e il 2 nella zona notte, le zone della zona giorno si possono nascondere dal display 2 e quelle della zona notte dal display 1). Se si spuntano entrambi i quadratini pur avendo una descrizione associata la zona non sarà visualizzata su nessuna interfaccia (display, app, web), ma solo da RegConfig o direttamente dal REG-DIN-8.
Pagina Zone
La pagina Zone è quella più articolata, ha addirittura 4 sottopagine:
Configurazione Zona/1
Configurazione Zona/2
Configurazione Zona/3
Parametri Zona
Le sottopagine più utilizzate e con più parametri significativi sono Configurazione/1 e Parametri Zona.
Le altre due sottopagine hanno soprattutto funzioni speciali da usare in casi particolari.
Dalla Pagina Configurazione Zona/2 si può accedere all’utilizzo:
del Segnale Forza Comfort (vedere https://setecna.atlassian.net/wiki/spaces/PUBDOCS/pages/3258778805)
della compensazione ambiente (vedere https://setecna.atlassian.net/wiki/spaces/PUBDOCS/pages/3258779433)
della modalità Antigelo per le Zone (vedere https://setecna.atlassian.net/wiki/spaces/PUBDOCS/pages/3258778720)
delle Zone collegate (vedere https://setecna.atlassian.net/wiki/spaces/PUBDOCS/pages/3258778664)
Dalla Pagina Configurazione Zona/3 si può accedere all’utilizzo:
delle zone in regime speciale (vedere https://setecna.atlassian.net/wiki/spaces/PUBDOCS/pages/3258778692)
della funzione Surplus fotovoltaico (vedere SURPLUS FUNCTION)
della funzione Economy per i deumidificatori (vedere https://setecna.atlassian.net/wiki/spaces/PUBDOCS/pages/3258779110)
Per creare una zona è sufficiente passare la tendina della colonna Orologio da NC (Non Configurato) a:
