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.

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

■

With open flue operation, the combustion air is

drawn from the installation room.

3. Verify that the heating system or the heating water

buffer cylinder is drawing off heat. Open the ther-

mostatic valves on the radiators if necessary.

4. Ensure that all heating flow and heating return

shut-off gate valves are open.

5. Check that all covers on the boiler are closed.

6. Switch ON the power supply, e.g. at a separate

MCB/fuse or a mains isolator.

7. Switch on the ON/OFF switch on the control unit.

The home screen is shown after a short time. Your

heating system and, if installed, remote controls

are ready for operation.

and date".

Switching the heating system on and off

To switch the heating system on and off, press

"START/STOP" on the boiler.

Steps to take in the event of overheating

The high limit safety cut-out and the thermally activa-

ted safety valve protect your boiler from overheating.

Note

Modifications to this component are prohibited and will

render all warranties void.

Replace faulty components only with genuine spare

parts from Viessmann.

Note

If the boiler overheats again after a short time or over-

heats regularly, notify your heating contractor.

Start-up/shutdown

Heat-up preparations

5679252

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.

Selecting a heating circuit

The heating of your interior can be split over several

heating circuits.

■

In the case of heating systems with several heating

circuits, for all central heating settings, first select the

heating circuit where you want to make a change.

■

This selection is not possible in heating systems with

only one heating circuit.

Example:

■

"Heating circuit 1" is the heating circuit for the

rooms occupied by you.

■

"Heating circuit 2" is the heating circuit for the

rooms of a separate apartment.

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
