The appliance is only intended to be
installed and operated in ventilation sys-
tems that comply with EN 1946-6, with
due attention paid to the associated
installation, service and operating
instructions. It is only designed for the
controlled mechanical ventilation of liv-
ing spaces.
Intended use presupposes that a fixed
installation in conjunction with permissi-
ble, system-specific components has
been carried out.
Commercial or industrial usage for a pur-
pose other than mechanical ventilation
of living spaces shall be deemed inap-
propriate.
Any usage beyond this must be
approved by the manufacturer for the
individual case.
Incorrect usage or operation of the appli-
ance (e.g. the appliance being opened
by the system user) is prohibited and
results in an exclusion of liability. Incor-
rect usage also occurs if the components
in the ventilation system are modified
from their intended function.
Note
The appliance is intended exclusively for
domestic use, i.e. even users who have
not had any instruction are able to oper-
ate the appliance safely.
Passive house use
Vitovent 300-W meets the requirements
for passive house use.
Commissioning
The commissioning and matching up of
the mechanical ventilation system to
local conditions and to the structural
characteristics of the building, as well as
the instruction of the user in operating
the system, must be carried out by your
HVAC contractor.
Note
These operating instructions also
describe functions that are only available
on some ventilation units or only with
accessories. These functions are not
specifically identified.
For questions relating to the range of
available functions and accessories for
your mechanical ventilation system,
check with your HVAC contractor.

Permissible ambient temperatures
The appliance may only be operated at
ambient temperatures inside the instal-
lation location of between 2 °C and
35 °C.
Terminology
To provide you with a better understand-
ing of the functions of your mechanical
ventilation system some terminology is
explained.
The terms are marked as follows:
Further information can be found
in chapter "Terminology" in the Ap-
pendix.

Brief absence, e.g. to go shopping (see
page 12):
■ Temporarily select a lower ventilation
stage, e.g. background ventilation.
Holidays (see page 20):
■ If you intend going away, select a
lower ventilation stage in "Manual"
mode for the duration of your absence,
e.g. background ventilation.
Contaminated filters (see page 36)
■ Regularly clean the filters inside the
ventilation unit and in the extract air
valves or, alternatively, replace them.
Tips for greater comfort
Increased relative humidity and/or
higher odour loads, e.g. when cooking
(see page 12)
■ Temporarily select a higher ventilation
stage, e.g. intensive ventilation.
Recommended ventilation stages
Select the ventilation state that suits the
current circumstances.
Ventilation stage Situation
Background ventilation
(minimum air flow rate)
Unoccupied building, e.g. during holidays
Reduced ventilation (re-
duced air flow rate)
Few occupants inside the building, e.g. Monday to
Friday during the daytime
Standard ventilation (stand-
ard air flow rate)
Standard use of the building by several occu-
pants
Intensive ventilation (maxi-
mum air flow rate)
■ Higher odour loads, e.g. when cooking
■ Increased humidity, e.g. when taking a shower
■ Utilisation of the building by may persons, e.g.
during a party

Time programs enable you to adapt the
mechanical ventilation system to your
personal preferences. In the time pro-
gram, divide the day into sections. These
are called periods. You determine the
ventilation stage to be applied during
these periods.
For recommended ventilation stage set-
tings, see page 9.
The following time programs are availa-
ble:
■"P1: Week"
The same time programs apply every
day.
■"P2: week/w-end" ("P2: Week/
Weekend")
You may select a different sequence
for Monday to Friday than for Saturday
and Sunday.
■"P3: days individual"
You can select a different sequence
for every day of the week.
When setting the time programs,
observe the following:
■ Time programs include up to 6
sequential periods per day ("Period
1" to "Period 6").
■ The period with the highest number is
disabled. This period will be ignored
in the time program sequence.
■ You can disable or delete periods (see
page 19).
■ You can enable disabled periods or
add periods (see page 18).
■ For every period select the start time.
■ The end time results from the start
time for the following period. This pre-
vents gaps between the individual
periods or an overlap of successive
periods.
■ If you have set "- - : - -" as start time,
then this period will be disabled. At the
same time, all of the following periods
will be deleted.
