AVVERTENZE
Gli umidificatori CAREL S.p.A. sono prodotti avanzati, il cui funzionamento è
specificato nella documentazione tecnica fornita col prodotto o scaricabile,
anche anteriormente all’acquisto, dal sito internet www.carel.com. Ogni
prodotto CAREL S.p.A., in relazione al suo avanzato livello tecnologico,
necessita di una fase di qualifica/configurazione/programmazione affinché
possa funzionare al meglio per l’applicazione specifica. La mancanza di tale
fase di studio, come indicata nel manuale, può generare malfunzionamenti
nei prodotti finali di cui CAREL S.p.A. non potrà essere ritenuta responsabile.
Il cliente (costruttore, progettista o installatore dell’equipaggiamento finale)
si assume ogni responsabilità e rischio in relazione alla configurazione del
prodotto per il raggiungimento dei risultati previsti in relazione all’installazione
e/o equipaggiamento finale specifico. CAREL S.p.A. in questo caso, previ
accordi specifici, può intervenire come consulente per la buona riuscita della
installazione/start-up macchina/utilizzo, ma in nessun caso può essere ritenuta
responsabile per il buon funzionamento dell’umidificatore ed impianto finale
qualora non siano state seguite le avvertenze o raccomandazioni descritte
in questo manuale o in altra documentazione tecnica del prodotto. In
particolare, senza esclusione dell’obbligo di osservare le anzidette avvertenze
o raccomandazioni, per un uso corretto del prodotto si raccomanda di
prestare attenzione alle seguenti avvertenze:
• PERICOLO SCOSSE ELETTRICHE
• L’umidificatore contiene componenti sotto tensione elettrica. Togliere
l’alimentazione di rete prima di accedere a parti interne o in caso di
manutenzione e durante l’installazione;
• PERICOLO PERDITE D’ACQUA
• l’umidificatore carica/scarica automaticamente e costantemente quantità
d’acqua. Malfunzionamenti nei collegamenti o nell’umidificatore possono
causare perdite;
• Negli umidificatori isotermici: PERICOLO DI USTIONE
• L’umidificatore contiene componenti ad alta temperatura (100°C/212°F);
• Negli umidificatori isotermici a gas: PERICOLO FUGHE DI GAS
• L’umidificatore è allacciato alla rete del gas. Malfunzionamenti nei
collegamenti o nell’umidificatore possono causare perdite.
• L’installazione del prodotto deve obbligatoriamente comprendere una
connessione di terra, utilizzando l’apposito morsetto di colore giallo-verde
presente nell’umidificatore.
• Condizioni ambientali e tensione di alimentazione devono essere conformi
ai valori specificati nelle etichette‘dati di targa’ del prodotto.
• Il prodotto è progettato esclusivamente per umidificare ambienti in
modo diretto o mediante sistemi di distribuzione (condotte). Inoltre per
gli umidificatori-adiabatici-atomizzatori-ad-acqua-in-pressione è prevista
anche l’umidificazione attraverso il telaio di atomizzazione.
• Installazione, utilizzo e manutenzione devono essere eseguite da personale
qualificato, consapevole delle precauzioni necessarie e in grado di
effettuare correttamente le operazioni richieste.
• Per la produzione di vapore si deve utilizzare esclusivamente acqua con
caratteristiche indicate nel presente manuale.
• Attenzione, in caso di umidificatori-adiabatici-atomizzatori-ad-acqua-in-
pressione è obbligatorio utilizzare acqua potabile demineralizzata (come
specificato nel manuale). Inoltre, è necessario raccogliere le particelle
d’acqua non assorbite dall’aria, attraverso la vasca raccogligoccia (nella
parte di umidificazione) e il separatore di gocce (nella parte di fine
umidificazione).
• Tutte le operazioni sul prodotto devo essere eseguite secondo le istruzioni
contenute nel presente manuale e nelle etichette applicate al prodotto. Usi
e modifiche non autorizzati dal produttore sono da considerarsi impropri.
CAREL S.p.A. non si assume alcuna responsabilità per tali utilizzi non
autorizzati.
• Non tentare di aprire l’umidificatore in modi diversi da quelli indicati nel
manuale.
• Attenersi alle normative vigenti nel luogo in cui si installa l’umidificatore.
• Tenere l’umidificatore fuori dalla portata di bambini e animali.
• Non installare e utilizzare il prodotto nelle vicinanze di oggetti che possono
danneggiarsi a contatto con l’acqua (o condensa d’acqua). CAREL S.p.A.
declina ogni responsabilità per danni conseguiti o diretti a seguito di
perdite d’acqua dell’umidificatore.
• Non utilizzare prodotti chimici corrosivi, solventi o detergenti aggressivi
per pulire le parti Interne ed esterne dell’umidificatore, salvo non vi siano
indicazioni specifiche nei manuali d’uso.
• Non fare cadere, battere o scuotere l’umidificatore, poiché le parti interne e
di rivestimento potrebbero subire danni irreparabili.
• Per prodotti umidificatori-adiabatici-atomizzatori-ad-acqua-in-pressione:
la distribuzione dell’acqua atomizzata deve essere condotta attraverso
apposito‘rack’di atomizzazione o attraverso sistemi di distribuzione previsti
da CAREL S.p.A.
• Per i prodotti isotermici: sono progettati per produrre vapore a pressione
atmosferica, e non vapore in pressione. CAREL S.p.A. sconsiglia e declina
ogni responsabilità per l’uso di dispositivi di distribuzione diversi da quelli
previsti.
CAREL S.p.A. adotta una politica di continuo sviluppo. Pertanto si riserva il
diritto di effettuare modifiche e miglioramenti a qualsiasi prodotto descritto
nel presente documento senza preavviso. I dati tecnici presenti nel manuale
possono subire modifiche senza obbligo di preavviso.

1. GENERAL FEATURES
ThT Thermostat is the CAREL room thermostat that allows users to
control the temperature in residential or light commercial environments,
providing of simplified interface that is ideal for end users. Temperature
set is simple and intuitive, using the knob on the front panel. thT also
allows the user to make some settings, such as the operating mode and
time bands. Compact dimensions and elegant design make it suitable for
all types of rooms, as well as being ideal both as a simplified HMI (Human
Unit Interface) for heat pumps, rooftop units, AHUs, etc. and as zone
controller display for centralised systems.
The RS485 serial connection over Modbus® protocol means architecture
can be implemented in which multiple displays are connected to a
controller to create synergic control logic with programmable controllers.
It can works in stand–alone mode as ambient thermostat or connected
to programmable controllers as zone control in the radiator systems too.
Depending on the model, thT thermostat is fitted for Flush or Wall
mounting and power supply is 230 Vac.
A temperature sensor is available in all models in order to manage
the comfort in the residential ambient, and a Humidity sensor only on
specific models.
thT is compatible with the main flush mount distribution boxes available
on the market.

Installation warnings
• These thT thermostats have been designed for wall or flush mount
assembly, on distribution boxes compliant with the standards in force;
• before performing any operations on the thermostat, disconnect the
power supply from the device by switching the main switch on the
electrical panel OFF. Then remove the front part of the thermostat from
the rear to make the electrical connections;

• for the serial connection use three-wire shielded cable, AWG 20-22. The
length of the network must not exceed 500 m. For extended networks
fit a 120 Ohm resistor between RX/TX+ and RX/TX- on the first and last
device, to avoid possible communication problems.
Assembly for the flush mounting
To fit the rear part of the terminal use a flush mount box with a min.
diameter of 65 mm and a minimum depth of 31 mm.
1. Detach the front from the rear of the thT thermostat using a
screwdriver;
2. Make the electrical connections according with the schematic;
3. Fasten the rear to the flush mount box using the 2 screws supplied:
4. Finally reposition the thT thermostat the original position and ensure
to fix it with clicks into place.

General notes
Avoid installing the terminal in environments with the following
characteristics:
• relative humidity greater than the value specified;
• strong vibrations or knocks;
• exposure to water sprays;
• exposure to aggressive and polluting atmospheres (e.g.: sulphur and
ammonia fumes, saline mist, smoke) so as to avoid corrosion and/or
oxidation;
• strong magnetic and/or radio frequency interference (for example,
near transmitting antenna);
• exposure to direct sunlight or the elements in general;
• large and rapid fluctuations in the room temperature;
• environments where explosives or mixes of flammable gases are
present;
• exposure to dust (formation of corrosive patina with possible oxidation
and reduction of insulation).
