Energy saving tips
Use the Vitotrol 100 setting options:
■ Do not overheat your rooms.
Every degree of room temperature reduction saves up to 6% of your heating bills.
Never set your room temperature
higher than 20 °C (see page 13).
■ Select the program that meets your current requirements:
– For short absences (e.g. shopping trips), select "Economy mode"
As long as economy mode is activated, the room temperature is reduced and DHW heating is off.
– If you are going away, set the "Hol-
As long as the holiday program is activated, the room temperature is reduced and DHW heating is off.
– If you don't want to heat the rooms and you don't require DHW for an extended period, select operating
mode "Frost pr." (see page 12).
Further recommendations:
■ Correct ventilation/airing.
Briefly open windows fully and at the same time close the thermostatic radiator valves.
■ Close roller shutters (if installed) at dusk.
■ Set thermostatic valves correctly.
■ Never cover radiators or thermostatic valves.
■ Controlled DHW consumption: A shower generally uses less energy than a full bath.
