USING THE UNIT

FAN SPEED ADJUSTMENT
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).

Vallox Simple Control panel

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.

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 off.
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 off automatically when the door of the ventilation unit is opened or the power is turned off. The maintenance reminder can also be set off manually.

The Vallox Simple Control panel, and the Vallox X-Line PTXP MC and PTXPA MC control hoods, VAK 0-10 VDC:
· The low speed is turned on, then higher-lower-higher
– Low speed under 4 V

Vallox Delico PTD EC and Vallox Capto PTC EC control hoods:
· The damper is closed, then open-closed-open · Press at a 1-5 second interval.

– High speed over 6 V

– The selected speed will always be turned on for 1-5 seconds

The service reminder will only be set off if it has been activated. Refer to the maintenance instructions for the necessary maintenance measures.

TROUBLESHOOTING TABLE
If the ventilation unit is affected by any of the errors listed in the table, the unit will report the error through the error relay, signal light, and circuit board LEDS. The number of flashes indicates the nature of the error.
The error relay can be connected to remote monitoring. NOTE! When remote monitoring is used, the signal light of the control panel cannot be turned on.

MAINTENANCE

BEFORE BEGINNING

MAINTENANCE WORK

When you open the door of Vallox 101 MC, the safety switch (S) cuts the power. Despite this, disconnect the power supply plug anyway. Always disconnect the power plug before starting maintenance on the Vallox 101 MC.
A
FILTERS

When the maintenance reminder becomes activated, S

check the cleanliness of the filters and replace them if

required. The Vallox ventilation unit has three air filters:

B

· Coarse filter for supply air (A) filters insects, heavy pollen and other relatively large foreign objects out of C the outdoor air.

· Fine filter for supply air (B) filters microscopic pollen and dust particles out of the supply air.

· Coarse filter for extract air (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.

The R model is shown in the figures. In the L model, the parts are mirrored.

E

G

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.

C

· Remove the sealing strip (E) above the heat recovery

cell in the direction of the arrow. Also remove the

D

extract air filter (C).

· Lift the heat recovery cell and pull it out of the unit.

IMPORTANT! Handle the cell carefully! For example, do not lift the cell 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, the heat recovery cell can be installed.

· Ensure that the lower support (F) is in place between the knobs at the bottom of the unit before the heat recovery cell is installed.

· Push the heat recovery cell in place. Also push the

sealing strip (E) in place so that the strip is supported

by the corner bracket (G) at the rear. Lastly, install the

extract air filter (C) in place.

MAINTENANCE

FANS

Check the cleanliness of the fans when servicing the filters and the heat recovery cell. Clean the fans as required. The fans are very sensitive to external impacts, and it is recommended that they be cleaned in place rather than removing them.

You can clean the fan blades with compressed air or by

brushing them gently. Do not remove or move the fan

blade balancing weights.

MAINTENANCE

CONDENSING WATER
In the heating season, the extract air humidity condenses to water. In new buildings, condensation runoff 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.

CONDENSING WATER CONNECTIONS

Installation of the Vallox Silent Klick siphon on the bottom pool
The delivery includes the Vallox Silent Klick siphon. A pipe will be connected to the siphon that leads the water that is condensed from the extract air to the floor drain (not directly into the sewer). The pipe must not rise after the siphon. The ventilation unit must be installed straight to ensure that condensing water can exit the unit unobstructed.
