Energy Saving Tips - Viessmann VITOTRONIC 200 Operating Instructions Manual

Energy saving tips

Central heating/Central cooling
Standard room temperature ("Set room tempera-
■
ture", see page 20):
Never overheat your home. Every degree of room
temperature reduction saves up to 6 % on your heat-
ing bills.
Never set your standard room temperature higher
than 20 °C.
Time program (see page 21):
■
Heat your home to the standard room temperature
during the day and the reduced temperature at night
(not suitable for underfloor heating). Set the time pro-
gram for this.
Operating program:
■
If you do not require central heating or cooling, select
one of the following operating programs:
"Only DHW" (see page 26):
–
If you require no heating for your home in summer,
but you need hot water.
"Standby mode" (see page 19):
–
If you don't need to heat your home and don't need
hot water for longer periods.
Short absence (see page 24):
■
Reduce the room temperature, for example when
you go shopping (not suitable for underfloor heating
systems). For this, select "Economy mode".
Holidays (see page 24):
■
If you are going away, select the "Holiday pro-
gram":
The room temperature will be reduced, and DHW
heating will be turned off. In connection with a venti-
lation unit, a lower ventilation stage will be selected.
Ventilation/airing:
■
To air a room, close the thermostatic valves and
briefly open the windows fully (if no domestic ventila-
tion system has been installed).
Roller shutters:
■
Close roller shutters (where installed) at dusk.
Tips for greater comfort
Central heating/Central cooling
Standard room temperature ("Set room tempera-
■
ture", see page 11):
You can select your individual preferred temperature
at any time in the standard menu.
Preferred heating circuit (see page 38):
■
If your heating system comprises several heating cir-
cuits, you can input the important settings for a pre-
ferred heating/cooling circuit directly in the standard
menu.
Time program (see page 21):
■
Make use of the time program. In the time program,
you can set time phases with different room temper-
atures, for example different temperatures for day
and night time.
Thermostatic valves:
■
Ensure that thermostatic valves are set correctly.
Radiators:
■
Never place things in front of radiators or thermo-
static valves.
DHW heating
DHW circulation pump (see page 27):
■
Only activate the DHW circulation pump for periods
in which DHW is regularly drawn off. Set the time
program for this.
DHW consumption:
■
Consider showering instead of running a bath. A
shower generally uses less energy than a full bath.
Domestic ventilation (in conjunction with ventila-
tion units)
Short absence (see pages 32 and 34):
■
Select a lower ventilation stage, for example when
going shopping. For this, select "Economy mode"
or the "Standard operation" operating program.
Holidays (see page 35):
■
If you are going away, select the "Holiday pro-
gram":
A lower ventilation stage will be selected. The room
temperature will be reduced, and DHW heating will
be turned off.
Own consumption of power (in conjunction with a
photovoltaic system)
Use the power generated by your photovoltaic sys-
■
tem for your heating system (see page 36).
For additional energy saving functions of the heat
pump control unit, please contact your heating contrac-
tor.
Heating water buffer cylinder (if installed, see
■
page 21):
Set the time program for the heating water buffer cyl-
inder so there is always sufficient heat for your heat-
ing circuits, for example to bridge power-OFF times
imposed by your local power supply utility.
Electric booster heater (if installed, see page 29):
■
Enable the electric booster heater and set up a time
program for it. The electric booster heater starts
automatically if large amounts of heat are suddenly
required.
"Active cooling mod." (see page 30):
■
After enabling the active cooling mode, a high cool-
ing capacity will be available for centrally cooling
your home, when required.
