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"
(see page 17).
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-

iday program" (see page 15).
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.
