USING THE UNIT
The fan speed of the Vallox ventilation unit is adjusted using a four-
step control.
The available speed options of the control switch are 1, 2, 3, and 4:
1.
Away mode. The ventilation efficiency can be temporarily
reduced when the apartment is unoccupied.
2-3. Standard mode. In standard mode, the air inside the
apartment is replaced once every two hours.
4.
Boost mode. Cooking, sauna, bathing, drying of clothes,
guests, and other similar situations can require that
ventilation be increased from the standard setting.
The fan speed can also be controlled through a separate Vallox
control hood, the Vallox ProControl panel, or directly through
voltage messages (0-10 V).

ADJUSTING THE SUPPLY AIR
TEMPERATURE AND SUMMER/WINTER
FUNCTION
The temperature of the air blown into the apartment can be
adjusted approximately b10 °C and +30 °C. The unit has an
automatic summer/winter function (a bypass flap).
• When the adjusted temperature is b10 °C and +30 °C,
the heat recovery cell is not bypassed, i.e. the unit is in winter
mode.
• In the OFF position, the unit is in the summer mode, i.e. post-
heating is turned off and the heat recovery cell is bypassed
when the outdoor temperature is above +14°C. The heat
recovery will be turned on when the outdoor temperature falls
below +12 °C.
• In the AUTO position, the unit will operate as follows around
the year: The default post-heating setting is +17 °C. The unit
will bypass the heat recovery cell when the temperature of the
outdoor air e14 °C. The heat recovery will be turned
on when the outdoor temperature falls below +12 °C. During
the bypass, post-heating is turned off.
The winter function of the ventilation unit
The limit value has been set in the factory for freezing of the heat
recovery cell. When this limit value is exceeded, the ventilation unit
starts to defrost the heat recovery cell by directing the outdoor air
past the heat recovery cell.
The duration of the defrost cycle is 15-45 min depending on the
amount of ice accumulated in the heat recovery cell and on the
extract air flow. The factory settings ensure optimal operation in
standard living and detached house conditions. Even though the
winter operation parameters can be adjusted for certain extreme
conditions, such as swimming pool facilities, it is always advisable
to contact Vallox maintenance services.
