Vitoligno 300-C Operating

Efficient and Clean Operation

Your boiler can be controlled within a range of 30 to

100% of its rated heating output. To avoid
unnecessary emissions in low load operation, the
appliances should be operated in the middle and upper
output range (adjusted to the relevant heat demand) if
possible. To avoid unnecessary cycling and to ensure
the longest possible runtimes, combination with a
modulating room or heating controller is ideal.
In terms of energy, a buffer tank and combination

with a solar thermal system are recommended. This
guarantees efficient and clean operation of your
heating system.

Dismantling

General Energy Saving Tips

To ensure efficient and clean operation of your heating
system, please note the following:
Only qualified and trained personnel may install and

adjust the system.
Only use the fuels specified in our operating

instructions (see chapter "Ordering fuel"). This is
essential for ensuring clean, efficient and reliable
operation of your heating system.
Regularly carry out the recommended maintenance

and cleaning work on your system. For details, see
chapter "Maintenance and repairs" in the operating
instructions. This guarantees not only the operational
reliability of the heating system and its safety
equipment, but also its efficient and clean operation.
For the best support of your heating system, we
recommend taking out a maintenance contract.
Have a heating contractor dismantle the boiler and the
associated system components.
With the following steps, you can save even more
energy:
Correct ventilation/airing.

Briefly open window A fully and at the same time
close thermostatic valves B.
Never overheat the interior; endeavour to achieve a

room temperature of 68°F (20°C); every degree of
room temperature reduction saves up to 6% of your
heating bills.
At dusk, close roller shutters (if installed) on windows.

Adjust thermostatic valves B correctly.

Never cover radiators C or thermostatic valves B.

Make use of the setting options offered by remote

control D, e.g. alternating standard temperature
with reduced room temperature.
Set the DHW temperature of DHW tank E at

control unit D.
Only activate the DHW circulation pump (via

switching times at the control unit) when DHW is
actually drawn.
Controlled use of DHW: A shower generally uses

less energy than a full bath.
