INTRODUCTION
INTRODUCTION
INTRODUCTION
In order to ensure that the indoor air presents no harm to health
and remains optimal also for the structures of the apartment,
ventilation must be kept on without disruptions. It is recommended
that ventilation be left turned on during long holidays also. This
keeps the indoor air fresh and prevents humidity from condensing
in the ventilation ducts and structures. It also reduces the risk of
moisture damage.
Operation of the Vallox ventilation unit can be controlled by the
following means:
• Through the control panel installed in the building
• Through the MyVallox Home local network connection and
the web interface
• Through the MyVallox Cloud cloud service and the web
interface
• Through a remote monitoring service or building automation
that uses voltage signals or Modbus messages
In addition to the built-in humidity sensor, ventilation can also be
adjusted automatically using the optional carbon dioxide and
humidity sensors. When these are used, ventilation remains optimal
even when the apartment is unoccupied.
Each user can use the week clock to adjust the ventilation to fit
their individual lifestyle.
The following settings will be configured during the setup of the
ventilation system:
• user interface language
• time and date
• system administrator password
• parental controls, if turned on
• fan settings
• user profile settings, such as the temperature.
The qualified ventilation installer must complete the fan settings
in accordance with the ventilation plan. Do not change these
settings.
STARTING THE UNIT
If you are starting the ventilation unit for the first time or after a
maintenance procedure, first connect it to the mains. During the
start-up, the diagnostics display will appear for a few seconds,
after which the main display of the At home profile opens.
If the ventilation unit was turned off from the control panel (see
Turning the Unit Off), you can start it by pressing any control panel
button.
WARNING
The unit is not intended for use
by children under 8 or by persons
with reduced sensory, physical or
mental capabilities, or whose lack of
knowledge and experience do not
ensure safe operation of the unit.
Such persons can use the unit
under supervision, or by following
the instructions of someone who is
responsible for their safety.
TIP
The MyVallox Control control panel
automatically switches to the sleep
mode when the Sleep time set in
the display settings has elapsed.
You can wake up the control panel by
pressing any control panel button.
NOTE
The first starting of the unit may take a
while, because of the software version
check.

SETUP WIZARD
EXPERT SETTINGS
FAN SETTINGS
To set the output ratio between the supply and extract air fans:
IMPORTANT
Adjust the air flows according to the values specified in the
ventilation plan. It is recommended that the air flows be adjusted
without having to choke the air flows at the valves. This is the most
energy-efficient set up.
First, set both values as close to the ideal value as possible
by looking at the supply and extract air fan curves. If the ratio
between the air flows is very high at first, the ventilation unit may
have to carry out extra defrosting cycles in sub-zero temperatures,
thus making adjustment of the air flows more complicated. Check
the air flows by measuring them at the valves, and fine-tune the
percentage values as required.
NOTE
If the outdoor air is extremely cold (below -10°C on an aluminium
cell or below -3°C on a plastic cell), the ventilation unit may have
to defrost the heat recovery cell. If this happens, the Defrosting
icon will be displayed on the control panel. The air flows cannot be
adjusted during defrosting.
SUPPLY AIR
1. Use the Plus and Minus buttons to set the supply air quantity
as a percentage of the maximum output ratio. The fan
speed (1/min) will change accordingly.
2. The supply air fan speed is now set.
3. Proceed to the next phase by pressing the Right arrow
button.
EXTRACT AIR
1. Set the air extract quantity as a percentage of the maximum
output ratio with the Plus or Minus buttons. The fan speed (1/
min) will change accordingly.
2. Select OK.
3. The extract air fan speed is now set.
4. Proceed to the next phase by selecting OK.
NOTE
You can browse the Fan settings by using the Right arrow button.
WARNING
The supply and extract air settings
have been completed by a
specialist during setup of the
ventilation unit. These settings
should be changed only when the
ventilation unit is reconfigured, and
not at any other time. Changing
the ventilation settings so that
overpressure is created can result
in damage to the structures of the
building.

PROFILE SETTINGS
NOTE
By default, the At home profile uses the higher basic ventilation fan
speed. We recommend that this basic ventilation setting be used
with the At home profile. Once you have set the fan speed for the
At home profile, the fan speed for the Away profile will by default
be set to -30% of the At home profile fan speed. We recommend
that the default fan speed settings be used. However, the settings
can be changed as required.
AT HOME AND AWAY PROFILES
To set the ventilation settings of the profiles:
1. Set the profile fan speed as a percentage of the maximum
output ratio by using the Plus or Minus buttons.
2. The fan speed value is now set for the At home profile.
3. Proceed to the next phase by selecting the Right
arrowbutton.
4. Set the desired supply air temperature for the profile with the
Plus or Minus buttons. You can adjust the temperature in the
range +10°C ... +25°C.
5. The profile supply air temperature is now set.
6. Proceed to the next phase by selecting the Right arrow
button.
7. Use the Plus and Minus buttons to turn the automatic fan
speed control on or off. This automatic regulation is based on
relative humidity of air.
8. The automatic fan speed control is now set.
9. Proceed to the next phase by selecting the Right arrow
button.
10. Use the Plus and Minus buttons to turn the automatic fan
speed control on or off. This automatic regulation is based on
carbon dioxide content.
11. The automatic fan speed control is now set.
12. Select OK.
13. Proceed to the settings of the next profile with the Right arrow
button.
NOTE
Once you have set the fan speed for the At home profile, the fan
speed for the Boost profile will by default be set to +30% of the At
home profile fan speed. It is recommended that this fan speed
setting be used for the Boost profile. However, the setting can be
changed as required.
BOOST PROFILE
The fan speed, supply air temperature, and the automatic fan
speed control (based on either relative humidity of air or carbon
dioxide level) is set for the Boost profile in the same way as for
the At home and Away profiles. The Boost profile also has a timer
setting.

It is recommended that a higher supply air fan speed be used
in the Fireplace mode to create overpressure in the ventilation
zone. Reducing the extract air fan speed is not recommended.
4. The supply air fan speed of the Fireplace profile is now set.
5. Proceed to the next phase by selecting the Right arrow
button.
6. Use the Plus and Minus buttons to set the extract air fan
