The GORENJE OGB 100 SMV9 water heater is equipped with a "smart" electronic control unit, which, in addition to setting and displaying the temperature of the water in the tank, offers many functions, for example, programming the operating time, indication of the amount of water in the tank, the "Vacation" program, fast heating, service diagnostics, but the most important innovation in the control unit is the Smart operating mode. After some time, the water heater automatically calculates the optimal operating mode based on the analysis of the data on the use of the device and ensures the minimum energy consumption with the required amount of ready hot water. Using the "Up" or "Down" buttons, you can adjust the temperature in the range from 10 to 75 C.
