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 26.
Do not 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 27.
■
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.
Heating curve/cooling curve: see page 28.
■
The heating curve enables you to individually adjust
the heating system to the actual heat demand in your
home. If set correctly, your rooms will be heated to
the standard room temperature all year round. The
same applies to the cooling curve.
Operating program
■
If you do not require central heating or cooling, select
one of the following operating programs:
– "Only DHW": see page 33.
If you require no heating for your home in summer,
but you require DHW.
– "Standby mode": see page 25.
If you don't need to heat your home and don't
require DHW for long periods.
Short absence: see page 30.
■
Reduce the room temperature, for example when
you go on a shopping trip (not suitable for underfloor
heating systems). For this, select "Economy
mode".
■ Holiday: see page 31.
If you are going away, set the "Holiday program":
The room temperature is reduced and DHW heating
is turned off. In connection with a ventilation unit, a
lower ventilation level will be selected.
■ Ventilation
Close the thermostatic valves when venting/airing.
Open windows fully for a short time (if no mechanical
ventilation system has been installed).
■ Roller shutters
Close roller shutters (if installed) at dusk.
■ Thermostatic valves
Ensure that thermostatic valves are properly adjus-
ted. Ask your contractor about this if necessary.
Radiators
■
Never cover radiators or thermostatic valves.
DHW heating
DHW circulation pump: see page 35.
■
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.
Mechanical ventilation (in conjunction with a venti-
lation unit)
Short absence: see pages 41 and 43.
■
If you are going out for a while, for example on a
shopping trip, reduce the ventilation level. For this,
select "Economy mode" or the "Standard opera-
tion" operating program.
Holiday: see page 44.
■
If you are going away, set the "Holiday program".
The ventilation level is reduced. The room tempera-
ture is reduced and DHW heating is turned off.
Utilisation of power generated on site (in conjunc-
tion with a photovoltaic system)
■ Use the power generated by your photovoltaic sys-
tem for your heating system: see page 46.
Utilising excess power (Smart Grid)
■ Utilise free or cheap excess power from the power
supply utility for your heating system: see page 47.
For additional energy saving functions of the heat
pump control unit, please contact your contractor.
