Page 4: Lcd Display
LCD display is provided with a full information LCD display: a wide section where you can easily check all the main data related to the boiler working. Functions and anomalies are displayed not only by codes but in particular by immediate symbols. This makes the information clear and prompt! Documento riservato –... - Page 5 Reliability and easiness of use is the result of the great combination of high reliable components and a meticulous choice of all the materials used. To make an example, the gas and combustion groups have already been tested in three years of production (more than 100.000 boilers manufactured), and the hydraulic group is the evolution of the existing group present in other models of WHB range.
