Manuale d’Uso
TERMOREGOLATORI ANALOGICI
Leggere attentamente tutte le istruzioni
I termoregolatori sono regolatori di temperatura analogici di dimensioni compatte AHT
48x48mm, che effettuano azioni di tipo 1B (norma CEI EN 60730-1) e che si adattano
perfettamente in applicazioni in cui è richiesta semplicità di utilizzo e robustezza, grazie
alla manopola centrale per la regolazione della temperatura e ai collegamenti rapidi tramite
faston. L’intervento del relè di uscita è segnalato tramite il led rosso posto sul frontale.
AVVERTENZE DI SICUREZZA
Durante l’installazione ed il funzionamento dello strumento è necessario
attenersi alle seguenti prescrizioni:
1) Lo strumento deve essere installato da persona competente rispettando
scrupolosamente gli schemi di collegamento
2) Lo strumento deve essere installato in un quadro tale da garantire, dopo
l’installazione, l’inaccessibilità ai morsetti
3) Non alimentare o collegare lo strumento se qualche parte di esso risulta
danneggiata
4) Nell’impianto elettrico dell’edificio in cui lo strumento va installato deve essere
presente un interruttore e un dispositivo di protezione dalle sovracorrenti
5) Gli strumenti garantiscono un isolamento principale tra le parti in bassa
tensione (250Vac) e le parti in bassissima tensione
6) Lo strumento è destinato ad essere utilizzato in ambienti con categoria di
sovratensione III e grado di inquinamento 2, secondo norma CEI EN 61010-1
7) Eventuali interruttori esterni collegati al termoregolatore devono garantire,
alle temperature di esercizio, un isolamento minimo di 250Vac o devono essere
protetti da equivalente isolamento

ANALOG HEAT REGULATORS
Read all instructions carefully
heat regulators are compact analog temperature regulators sized , AHT 48x48 mm
that are destined for 1B type actions (EN 60730-1 standard) and that perfectly suit
applicationsthatrequireeaseofuseandsturdiness,thankstothetemperature
regulation and the rapid connections via faston. The triggering of the output relay is
signalled by the red LED placed on the front panel.
SAFETY WARNINGS
During the installation and operation of the instrument, proceed in accordance
with the instructions below:
1) The instrument should be installed by a competent operator following the
installation diagrams carefully
2) The instrument should be installed in a panel from which no access can be
gained to the terminals after installation
3) Do not power or connect the instrument if any part of it is damaged
4) The electrical system of the building in which the instruments is to be installed
should have a switch and a protective device against over-currents
5) The instruments guarantee a main insulation between low voltage parts
(250Vac) and ultra low voltage parts
6) The instrument is designed for installations with over-voltage category III and
pollution level 2, in accordance with the EN 61010-1 standard
7) Any external switches connected to the heat regulator must guarantee, at the
operating temperatures, a minimum insulation of 250Vac or must be protected
by an equivalent insulation

•
Install the heat regulator as far as possible from sources that can generate
electromagneticdisturbances,suchasmotors,telebrakers,relays,solenoidvalves,etc.
• Use6.3mmfemalefastonsforconnectionstotheheatregulator.
• Makesurethatthecablesoftheprobearekeptseparatefromthepowersupplying
cables or the positive leads to avoid electromagnetic disturbances.
The use of shielded probe cables is recommended; the shielding must be earthed
only in one point, usually near the instrument.
