Ce thermostat fonctionne sur des systèmes 24 V. Il ne fonctionnera PAS sur les
systèmes 120/240 V.
Ce thermostat contient une pile au lithium pouvant contenir du perchlorate.
Perchlorate — peut exiger une manipulation particulière.
Consultez le site www.dtsc.ca.gov/hazardouswaste/perchlorate
AVIS RELATIF AU MERCURE : Ne jetez pas l’ancien thermostat dans la poubelle
s’il contient du mercure dans un tube scellé. Contactez la Thermostat Recycling
Corporation à l’adresse www.thermostat-recycle.org ou appelez au 1-800-238-8192
pour savoir comment et où mettre au rebut votre thermostat usagé.
AVIS : Pour éviter d’endommager le compresseur, ne faites pas fonctionner le
climatiseur si la température extérieure est inférieure à 10 °C (50 °F).
