Fan Speed Adjustment - Vallox TSK Multi 80 MC R Manual

FAN SPEED ADJUSTMENT

The fan speed of the Vallox ventilation unit is adjusted
using a four-step control (optional).
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 (optional), the Vallox ProControl
control panel (optional), or directly through voltage
messages (0-11,4 V).
ADJUSTING THE SUPPLY AIR TEMPERATURE
AND SUMMER/WINTER FUNCTION
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.
