8.5 REGULATION THERMOSTAT OF THE ELECTRIC HEATER
The auxiliary electric heater is equipped with a thermostat for regulation; the access to this component takes place by removing
the plastic frontal cover. Such control allows a variation of temperature between 15 and 75°C; each notch corresponds to a
temperature variation of 10°C.

malfunctions on the legionella cycle control (For this purpose it is required to read carefully the paragraph Errore. L'origine
riferimento non è stata trovata.).
