Energy Saving Tips
• Standard room temperature (see page 9):
Do not overheat your home. Every degree of room temperature reduction saves up to 6 % on
your heating bills.
• Time program (see page 6):
Heat your home to the standard room temperature during the day and the reduced temperature
at night. Set this via the time program.
• Short absence (see page 10):
Reduce the room temperature if you are going out shopping, for example. For this, select
"Economy mode".
• Holidays (see page 9):
If you are going away, select the "Holiday program": The room temperature is reduced, and DHW
heating is turned off.
• Airing:
Close the thermostatic valves when airing. Open the windows fully for a brief time.
• Roller shutters:
Close roller shutters (if installed) at dusk.
• Thermostatic valves:
Ensure that thermostatic valves are properly adjusted.
• Radiators:
Never cover radiators or thermostatic valves.
For additional energy saving functions of the Vitotronic control unit, please contact your heating
contractor.
Tips for Greater Comfort
• Time program (see page 6):
Make use of the time program. In the time program, you can set time phases with different room
temperatures, for example different temperatures for day and night time.
• "Party mode" (see page 10):
If you want to heat rooms to a different temperature from the one set in the time program,
select "Party mode".
Example: Due to the time program settings, your home is heated to a reduced room temperature
during late evening, but you have visitors staying late.
