USING THE UNIT
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 eciency 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).
Vallox Simple Control control panel
Vallox ProControl control panel
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 o 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 o.
Adjusting supply air temperature
FAN SPEED ADJUSTMENT
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.

USING THE UNIT
FIREPLACE SWITCH
A switch with timer functions can be connected to the unit. The switch stops the
extract air fan when the fireplace is being used. NOTE! Starting up the extract
air fan can reduce the draw of the fireplace! In winter, this can disturb the winter
mode of the ventilation unit. The situation will return to normal soon after the
fireplace mode is turned o.
ADJUSTING THE SUPPLY AND EXTRACT AIR
RATIO
This function might be needed when the air flows are adjusted at the valves
during installation. The user does not need to adjust this function once
the valves have been adjusted, and indeed should not adjust it at all. A
potentiometer can be used to reduce the supply or extract air flow as required.
When the potentiometer is set roughly in the centre position, neither the supply
nor the extract air flow has been reduced. When the potentiometer is turned
anti-clockwise, the supply air flow is reduced, and when the potentiometer is
turned clockwise, the extract air flow is reduced.

MAINTENANCE REMINDER
If a signal light is connected to the connectors of the unit’s error relay, the unit will send a reminder of service need every
six months,. If connected, the signal light will flash every second. Sounds made by the relay can then be heard from
inside the unit. The maintenance reminder will be set o automatically when the door of the ventilation unit is opened or
the power is turned o.
The maintenance reminder can also be set o manually.
The Vallox Simple Control control panel,
and the Vallox X-Line PTXP MC and
PTXPA MC control hoods, VAK 0-11,4 VDC:
• The low speed is turned on, then higher-lower-higher
- Low speed under 4 V
- High speed over 6 V
- The selected speed will always be turned on
for 1-5 seconds
Vallox Capto PTC EC control hood:
• The damper is closed, then open-closed-open
• Press at a 1-5 second interval.
The service reminder will only be set o if it has been activated. Refer to the maintenance instructions for the necessary
maintenance measures.

BEFORE BEGINNING
MAINTENANCE WORK
The safety switch (S) automatically turns o the power
when the door of the Vallox TSK Multi 50/80 MC ventilation
unit is opened. Always disconnect the power plug before
starting the Vallox TSK Multi 50/80 MC ventilation unit
maintenance.
FILTERS
When the maintenance reminder becomes activated,
check the cleanliness of the filters and replace them if
required.The Vallox ventilation unit has three air filters:
• Class G4 coarse filter (A) filters insects, heavy pollen
and other relatively large foreign objects out of the
outdoor air.
• Class F7 fine filter (B) filters microscopic pollen and
dust particles out of the supply air.
• Class G4 coarse filter (C) filters the extract air and
keeps the heat recovery cell clean.
Using original Vallox filters ensures the best operation
of the ventilation unit and the best filtering results. The
filter replacement interval depends on the ambient dust
concentration. It is recommended that the filters be
replaced every spring and autumn, or at the very least
once a year.

CONDENSING WATER
In the heating season, the extract air humidity condenses
to water. In new buildings, condensation runo can form
rapidly. Condensed water must be able to freely leave the
unit. At some time before the heating season begins (e.g.
during autumn maintenance), check that the condensing
water outlets in the bottom pool are not clogged. To check
this, pour some water into the pool. Clean as required.
Water must at all times be kept out of the electrical system.
See the condensing water connections on page 15.
HEAT RECOVERY CELL
Check that the heat recovery cell (D) is clean roughly
once a year when the filters are being replaced. Clean by
washing as required.
• Pull the coarse filters including the frames out of the
unit (A and C). Also remove the fine filter, if any (C).
• Remove the sealing strip (E) above the heat recovery
cell in the direction of the arrow.
• Once you have removed the sealing strip, pull the
heat recovery cell out of the unit.
IMPORTANT! Handle the cell carefully! For example, do
not lift the cells by the layers. The cell layers are very thin
and easily damaged.
If the heat recovery cell is dirty, clean it by immersing it in
water containing a small amount of a mild detergent. Rinse
the heat recovery cell clean with a water spray. When all
the water has drained from between the layers, push the
cell recovery cell back in place. Lastly, push the sealing
strip back in place.

INSTALLATION
Mounting
The Vallox TSK Multi 50/80 MC is normally installed on the
ceiling using the four mounting hooks delivered with the unit.
The weight of the unit (45 kg) must be taken into account when
mounting the unit.
Wall structure
The wall structure must be observed in the mounting.
Avoid mounting the unit on hollow, echoing intermediate
walls and on bedroom walls, or take measures to prevent
conduction of noise.
INSTALLATION SITE
Vallox TSK Multi 50/80 MC must be installed in a location
where the temperature remains above +10 °C. When the
unit is installed without a protective enclosure, the location
must be chosen so that its noise does not cause any
disturbance. Such locations include storage premises and
technical spaces.
Important! The whole length of the outdoor air duct to the unit
and exhaust air duct from the unit must be insulated using
closed cell insulation.
CONDENSING WATER
The delivery includes a water seal and an elbow for connecting the pipe that leads the water condensed from the extract air to the
floor drain (not directly into the sewer). The pipe must not rise after the water seal. See the accessory bag for further instructions
on the installation of the water seal and the elbow.
