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 control panel, 

or directly through voltage messages (0-10 V).

The temperature of the air blown into the apartment can 

be adjusted approximately between +10 °C and +30 °C.  

The unit has an automatic summer/winter function  

(a bypass flap).

•  When the adjusted temperature is between +10 °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 exceeds 

+14 °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.
