Note: The Legrand 03740 is an Omnipolar device, meaning it breaks both Phase and Neutral simultaneously for safety. Ensure the power is off before installation.
D: Posso programmare intervalli inferiori a 15 minuti? R: No. Il Legrand 03740 ha una risoluzione di 15 minuti. Per intervalli più brevi (es. 1 minuto) occorre un timer digitale (es. Legrand 03747).
D: Perché il mio timer ha i numeri romani (I, II, III) invece che 1,2,3? R: È una variante estetica. I = 1 ora, XII = 12 ore, ripetuti due volte per il ciclo di 24 ore.
D: Il manuale originale dov’è? R: Legrand non produce più manuali cartacei. Puoi scaricarlo dal sito Legrand Italia → Supporto → Cerca "03740". In alternativa, le istruzioni qui descritte sono le medesime.
D: Posso usare questo timer per una caldaia o un motore? R: Sì, ma verifica la corrente assorbita. Per carichi induttivi (motori, elettrovalvole), la portata massima consigliata è 10 A. Per caldaie va benissimo. Manuale Timer Legrand 03740
