If the heating system develops a fault
Danger
Fault messages indicate faults in
the heating system. If faults are not
rectified, they can have life threat-
ening consequences.
Do not acknowledge fault mes-
sages several times in quick suc-
cession. Inform your heating con-
tractor so the cause can be ana-
lysed and the fault rectified.
Conditions for siting
Danger
Sealed vents result in a lack of
combustion air. This leads to incom-
plete combustion and the formation
of life threatening carbon monoxide.
Never cover or close existing vents.
Do not make any subsequent modi-
fications to the building characteris-
tics that could affect safe operation
(e.g. cable/pipework routing, clad-
ding or partitions).
Danger
Easily flammable liquids and mate-
rials e.g. naphtha/petrol, solvents,
cleaning agents, paints or paper,
can trigger deflagration and fire.
Never store easily flammable sub-
stances in the boiler room or in
direct proximity to the heating sys-
tem.
!Please note
Incorrect ambient conditions can
lead to heating system damage and
can put safe operation at risk.
■Ensure ambient temperatures are
above 0 °C and below 35 °C.
■Prevent air contamination by halo-
genated hydrocarbons (e.g. as
contained in paints, solvents or
cleaning fluids) and excessive
dust (e.g. through grinding/polish-
ing work).
■Avoid continuously high humidity
levels (e.g. through continuous
drying of washing).
Extractors
The operation of appliances that extract
air to the outside (cooker hoods, extrac-
tors, air conditioning units, etc.) can cre-
ate negative pressure. If the boiler is
operated at the same time, this can lead
to a reverse flow of flue gas.
Danger
The simultaneous operation of the
boiler and appliances that extract
air to the outside can result in life
threatening poisoning due to a
reverse flow of flue gas.
Take suitable steps to ensure an
adequate supply of combustion air.
If necessary, contact your heating
contractor.

Incorrect usage or operation of the appliance (e.g. the
appliance being operated for longer periods when
open) is prohibited and will result in an exclusion of lia-
bility. Incorrect usage also occurs if the components in
the heating system are modified from their intended
use (e.g. if the flue gas and ventilation air paths are
sealed) or if other fuels than those intended for this
appliance are used.
Appliance description
The Vitoligno 300-H is an automatic boiler suitable for
burning woodchips and pellets.
Commissioning
The commissioning and matching of the appliance to
local conditions and building characteristics, as well as
instructing the user in the operation of the system,
must be carried out by your contractor.
As the user of new combustion equipment, you may be
obliged to notify your local flue gas inspector of the
installation [check local regulations]. Your local flue gas
inspector will also inform you [where appropriate]
about work that may have to be carried out on your
combustion equipment (such as regular checks, clean-
ing).
Recurring emissions tests
■Your heating contractor must prepare the boiler for
this test.
■Notify your heating contractor approx. 2 weeks prior
to the next emissions test being due.
■Ensure that suitable fuel is available. See chapter
Ordering fuel.
Prepare and carry out the emissions tests according to
the 1st BImSchV:
See installation and service instructions
Your system is preset
Your heating system is preset at the factory and is
therefore ready for operation following commissioning
by your contractor:
Central heating
■Between 06:00 h and 22:00 h, rooms are heated to
20 °C "Set room temp" (standard room tempera-
ture).
■Between 22:00 h and 06:00 h, rooms are heated
with "Set red room temp" (room temperature for
reduced heating operation, night setback).
DHW heating
■Between 06:00 and 22:00 h, the DHW is heated to
60 °C "Set DHW temperature". Any installed DHW
circulation pump is switched on.
■Between 22:00 and 06:00 h, the DHW cylinder is not
reheated. Any installed DHW circulation pump is
switched off.
Note
Any DHW heating begun before 22:00 h is termina-
ted.

Date and time
■The date and time were set by your heating contrac-
tor.
You can change the settings at any time to suit your
individual requirements.
Power failure
All settings are saved if there is a power failure.
Energy saving tips
Use the adjustment options offered by your boiler con-
trol unit:
■For central heating, select the operating program
that meets your current requirements:
–For brief periods of absence (a few hours,
for example when out shopping), select "Economy
mode". See page 23.
The room temperature is reduced for as long as
economy mode is activated.
–If you are going away, select the "Holiday pro-
gram". See page 24.
The operating program for central heating is auto-
matically set to "Standby mode" while the holiday
program is active.
–If you do not want to heat the rooms and you do
not require DHW for an extended period, set the
"Standby mode" operating program for the rele-
vant heating circuits and for DHW.
–See page 21 for the relevant heating circuits
–See page 27 for DHW heating
■Do not set the temperature inside the DHW cylinder
too high. See page 27.
You can further save energy by taking the following steps:
AC
E
B
D
Fig. 1
■Correct ventilation/airing:
Open windows A wide for a short time. During this
time, close thermostatic valves B.
■Do not overheat the rooms; aim for a room tempera-
ture of 20 °C. Every degree of room temperature
reduction saves up to 6 % on your heating bills.
■Close shutters (where installed) on the windows at
dusk.
■Ensure that thermostatic valves B are properly
adjusted.
■Never cover or obstruct radiators C or thermostatic
valves B.
■Make use of the setting options of control unit D,
e.g. "standard room temperature" alternating with
"reduced room temperature".
■Set the DHW temperature of DHW cylinder E at
control unit D.
■Only enable the DHW circulation pump (via switching
times at the control unit) when DHW is being drawn
off.
■Check your hot water consumption: A shower
requires less energy than a full bath.

High limit safety cut-out
Triggering the function
If the boiler water temperature exceeds 95 °C, the
thermally activated safety valve triggers heat transfer
via the safety heat exchanger.
If the boiler water temperature exceeds 100 °C the
high limit safety cut-out responds.
Note
The high limit safety cut-out can only be reset man-
ually.
Cancelling the function
The high limit safety cut-out can only be reset
(unlocked) once the boiler water temperature has
reached approx. 70 °C.
After each triggering of the high limit safety cut-out,
check that the thermally activated safety valve is reset.
!Please note
If the high limit safety cut-out is not reset, it
inhibits the safety equipment function and can
damage the boiler.
Always carry out the following steps.

Time program
Setting the time program for central heating
The time when the heating circuit delivers central heat-
ing with standard or reduced room temperature is
dependent on the settings of the switching times for
the relevant day (4 possible time phases).
■If one or more time phases are set, central heating
with standard room temperature will be active for
those times.
■If no time phases are set, central heating will be ena-
bled for the whole day with reduced room tempera-
ture.

■For central heating, up to 4 changes per day
between standard and reduced room temperature
can be programmed (4 time phases).
■At the factory, time phase ! from 06:00 to 22:00 h
is set for all days of the week. During that time, the
rooms are heated to the standard room temperature.
■You can set switching times individually for the fol-
lowing days or parts of the week:
–The same for every day: Monday to Sunday
–For individual parts of the week: Monday to Friday
and Saturday to Sunday
–For every day individually: Monday, Tuesday, etc.
■In the "Extended menu", you can check the current
time program under "Information". See page 39.
Note
When setting the switching times, please bear in mind
that your heating system requires some time to heat
the rooms to the required temperature.

Restoring the time phases to the factory settings
Note
The time phases are only restored to the factory set-
tings when you reset all settings for the selected heat-
ing circuits.
The steps for restoring factory settings can be found
on page.
Heating curve
Adjusting the heating curves
■You can alter the heating characteristics if the room
temperature does not meet your requirements for
any prolonged period of time.
■You alter the characteristics by changing the slope
and level of the heating curve. For more information
regarding the heating curve, see page.
■Please observe the modified heating characteristics
over several days (if possible, wait for a major
change in the weather) before making further adjust-
ments.
Changing the slope and level
For assistance, use the following table.
Heating characteristics Measure Example
The living space is too cold during the
cold season.
Adjust the heating curve slope to the next
highest value (e.g. 1.5).
Slope 1.5
Level 0 K
The living space is too hot during the
cold season.
Adjust the heating curve slope to the next
lowest value (e.g. 1.3).
Slope 1.3
Level 0 K
The living space is too cold during
spring/autumn and during the cold
season.
Adjust the heating curve level to a higher
value (e.g. +3).
Slope 1.4
Level 3 K
The living space is too hot during
spring/autumn and during the cold
season.
Adjust the heating curve level to a lower
value (e.g. −3).
Slope 1.4
Level -3 K
The living space is too cold during
spring/autumn, but warm enough dur-
ing the cold season.
Adjust the heating curve slope to the next
lower value and the level to a higher val-
ue.
Slope 1.3
Level 3 K
The living space is too hot during
spring/autumn, but warm enough dur-
ing the cold season.
Set the heating curve slope to the next
higher value and the level to a lower val-
ue.
Slope 1.5
