Adjustment of supply air temperature and summer/winter

function

The temperature of air coming to the dwelling can be adjusted between circa +10 °C and

+30 °C. The midpoint of the adjustment range is circa +20 °C. When supply air temperature

adjustment has been turned in the OFF position, post-heating is not active. This means that

summer function is activated for the ventilation unit. The unit has a motorised summer/winter

function. When the summer function is on, the heat recovery cell is bypassed as soon as

outdoor air temperature has risen above +14 °C. When outdoor air temperature goes below

+12 °C, the unit starts to recover heat. When supply air temperature adjustment is in the

AUTO position, automatic function is activated for the unit. In this case, the setpoint for post-

heating is +17 °C and the heat recovery cell is bypassed automatically according to outdoor

temperatures as indicated above. When the unit bypasses the heat recovery cell, in which

case summer function is activated, post-heating is off.

Fireplace switch function

It is possible to connect a timer-operated switch to the unit. The switch stops the extract air fan

during the time when the ﬁreplace is heated. NOTE! The starting of the extract air fan may

weaken draught in the ﬁreplace! In winter, this situation may disturb the winter function of the

unit. The situation will normalise in a while, after the ﬁreplace function stops.

Winter function of ventilation unit

A threshold value has been set at the factory for the freezing of the heat recovery cell. When

the threshold is exceeded, the ventilation unit starts to melt the heat recovery cell by guiding

outdoor air ﬂow to bypass the heat recovery cell.

A normal melting period takes from 15 to 45 minutes depending on the extent of ice on

the heat recovery cell and on the amount of extract air ﬂow. The unit has been optimised to

operate on the factory settings in normal operation in dwellings and detached houses. The

winter function parameters can be adjusted for extreme conditions, such as a swimming bath,

but even then it is advisable to contact Vallox Maintenance.

Adjustment of relationship between supply and extract air

This feature may be useful when adjusting air ﬂows at the valves during mounting. After the

valves have been adjusted, a user does not need, and must not, touch the adjustment. When

needed, supply or extract air ﬂow can be reduced at the potentiometer.

When the potentiometer is approximately halfway, supply and extract air ﬂow have not been

reduced. Turning the potentiometer anticlockwise reduces air ﬂow on the supply side, and

turning it clockwise reduces air ﬂow on the extract side.

Maintenance reminder

The unit reminds of the need for maintenance every six months if an indicator (not standard)

has been connected to the connectors of the fault signal relay. The indicator then blinks at

one-second intervals. The maintenance reminder is reset when the door of the ventilation unit

is opened. See the maintenance instructions for information on the necessary maintenance

activities.

Four-step control switch

Fan speed adjustment

The fan speed of a Vallox ventilation unit can be controlled with a control switch (option), with

a separate cooker hood (option) or directly with a 0–11,4 V voltage signal.

Speeds 1, 2, 3 and 4 can be selected at the control switch.

1. Operation during absence. When the dwelling is empty, ventilation can be reduced

temporarily.

2–3. Normal operation. In normal operation, air has to be replaced once every two hours.

4. Boosted operation. Cooking, taking a sauna bath, washing, drying clothes, using

the toilet, having guests or a corresponding situation may cause a need for higher

ventilation than in normal operation.

MAINTENANCE INSTRUCTIONS

MAINTENANCE

Before starting maintenance

operations

When you open the VALLOX TSK Multi 50/80

MC unit, the safety switch of the door (T) turns

power off from the unit. In spite of that, always

disconnect the plug of the VALLOX TSK Multi

50/80 MC unit before starting maintenance

operations.

VALLOX TSK Multi 50/80 MC ﬁlters and heat recovery cell

The units are available as right- and left-handed models. In a right-handed

(model R) model, outdoor air comes to the unit from the right side of the

centre line, as shown in the instructions. In a left-handed (model L) unit, out-

door comes from the left side of the unit. The ﬁlters, summer/winter damper

and heating radiator also change places correspondingly.

Filters

When the maintenance reminder gives an alarm, the cleanliness of

the ﬁlters must be checked. Outdoor air is ﬁltered in the unit with two

kinds of ﬁlters. A coarse ﬁlter (A) ﬁlters off insects, heavy pollen and

other dust. An F7 class ﬁne ﬁlter (B) ﬁlters off ﬁne dust invisible to the

eye. Extract air is ﬁltered with a coarse ﬁlter (C).

By using original Vallox ﬁlters you ensure good operation of the

ventilation unit and the best ﬁltering result. The replacement interval

of ﬁlters depends on dust content in ambient air. It is recommended to

replace fans in spring and autumn, but at least once a year.

Heat recovery cell

When you replace the ﬁlters, you are also advised to check the

cleanliness of the heat recovery (HR) cell (D) at about two-year

intervals.

The G4 ﬁlters and their supports, the sealing ledge (E) above the HR

cell and the side sealing ledge (F) must be pulled off before the cell

can be detached. When the sealing ledge has been removed, the

HR cell can be pulled out of the unit.

Note! The laminas of the HR cell are very thin and get easily

damaged. The correct way to remove the HR cell is to put your

hands behind the HR cell and slowly pull it off. If the HR cell is dirty,

wash it by immersing it in a solution of water with washing-up liquid.

Rinse the HR cell clean with a jet of water. When water has drained

from between the laminas, you can push the HR cell back in place.

Finally, push the sealing ledges and ﬁlters in place.

C A

Detaching of HR cell

Pull the coarse ﬁlters and their frames out of the unit. Also remove the ﬁne

ﬁlter if it has been used. You can then pull out the sealing ledges situated

on top and on the sides of the HR cell. When the sealing ledges have been

removed, the HR cell can be pulled out of the unit. Note! The laminas of the

HR cell are very thin and get easily damaged.

Condensing water

During the heating season, humidity of extract air condenses into

condensing water. Water formation may be abundant in new

buildings or if ventilation is low compared to the humidity build-up

caused by the residents.

Condensing water needs to ﬂow out from the ventilation unit without

hindrance. In carrying out maintenance, for instance in autumn

before the beginning of the heating season, make sure that the

condensing water outlet (L) in the bottom tank is not clogged. You

can check it by pouring a little water in the tank. Clean if needed.

Do not let water ﬂow into electrical devices. The unit comes with

a condensing outlet (in the ﬁgure) equipped with an airlock and

an outlet without airlock that takes less space. If you use the outlet

without airlock, you have to mount an airlock somewhere between

the discharge pipes (the accessory bag contains the parts needed).

An airlock guarantees the removal of condensing water and

silencing of any sounds.

Fastening

VALLOX TSK Multi 50/80 MC is mounted

normally to a ceiling with four fastening hooks

delivered with the unit. When fastening, take

into account that the unit weighs 45 kg.

Important!

Mount the unit horizontally level to make

sure that the condensing water gathering

in the bottom tank runs into the condensing

outlet.

Condensing water

The delivery includes a water seal. By

connecting a pipe to the water seal the

water condensing from extract air can be

led to a ﬂoor drain (not directly to the drain).

The pipe must not rise after the water seal.

For further instructions on the mounting of

the water seal and outlet, see the accessory

bag.
