VENTILATION UNIT CONTROL

Ventilation unit control options
Operation of the Vallox ventilation unit can be controlled by the following means:

• Through a MyVallox control panel installed in the building.
• Through the MyVallox Home local area network connection and the MyVallox Home/Cloud user interface.
• Through the MyVallox Cloud service and the MyVallox Home/Cloud user interface.
• Through a remote monitoring service or building automation that uses voltage signals or Modbus messages.

In addition to the integrated humidity and carbon dioxide sensor, ventilation can also be adjusted automatically by using the optional carbon dioxide, humidity, or VOC (air quality) sensor. When these are used, ventilation remains optimal even when the dwelling is unoccupied. Each user can use the week clock to adjust the ventilation to fit their individual lifestyle.

The ventilation unit’s integrated humidity and carbon dioxide sensors adjust ventilation automatically according to the need. In addition, ventilation can be automated by using optional carbon dioxide, humidity or air quality (VOC) sensors.

Filter reminder
The unit reminds of the need to change filters in the popup window of the compatible MyVallox control panel, in the MyVallox Home/Cloud user interface and by changing the relay status, provided that a signal light has been connected to the relay connectors and Maintenance reminder has been chosen as the relay setting.

The filter reminder can be acknowledged by the following means:

• from the MyVallox control panel
• from the MyVallox Home/Cloud user interface
• with the Vallox Delico PTD EC and Vallox Capto PTC EC cooker hoods — Push the damper position button four times at less than one-second intervals, starting from the Damper closed position.

Ventilation unit setup without a control panel
The ventilation unit setup can also be completed without a control panel. For instructions, please go to: https://vallox.techmanuals.info/ValloxMV/ENG/help/webhelp
See the instructions provided in the section Connecting the ventilation unit to the computer.

Connecting the ventilation unit to the cloud service
The ventilation unit can be connected to the MyVallox Cloud service. The cloud service allows for controlling ventilation remotely also, using e.g. a smartphone or tablet. Also the unit software is updated automatically through the cloud service. To connect to the cloud service, the ventilation unit must be connected to the Internet via LAN and registered with the cloud service. At the same time you create a MyVallox Cloud account for yourself. Read more about the service at www.myvallox.com.

IMPORTANT
Prolonged overpressure can result in damage to the structures of the building.

IMPORTANT Apartment-specific ventilation units allow residents to adjust the ventilation efficiency. Ventilation is controlled based on the need e.g. through the cooker hood, ventilation control panel, or a separate control center. In order to ensure that the indoor air presents no harm to health and remains optimal for the structures of the building, ventilation must be kept on without disruptions. It is recommended that ventilation be turned on during long holidays also. This keeps the indoor air fresh and prevents humidity from condensing in the ventilation ducts and structures. It also reduces the risk of moisture damage.

MAIN PARTS

INSTALLATION

MOUNTING ON THE WALL

NOTE
Avoid mounting the unit on a hollow, echoing partition wall or on a bedroom wall, or prevent the conduction of sound.
The minimum distance between the top of the unit and the finished ceiling surface is 30 mm. Note that during mounting the unit rises 10 mm higher than the final height.

Mount the ventilation unit onto the wall with a mounting plate
(optional), as shown in the figures below. Make sure that the unit is horizontally level after mounting.

NOTE
When installing the unit, reserve a space of at least 500 mm in front of the unit for servicing purposes.

NOTE
Mount the ventilation unit in a place where the temperature does not fall below +10°C.

MOUNTING ON THE CEILING
Vallox 99 MV can be equipped with an optional ceiling mounting plate. To attach the ceiling mounting plate:

• On rafter frames or other frame structures with M8 thread bars so that they withstand the weight of the unit.
• Ensure that the installation plate is horizontally level, as this determines the position of the unit.
• The top edge of the white covering strip of the ceiling mounting plate can be installed against the ceiling. Alternatively, a concealed mounting method can be used, in which case the ceiling can be 30 mm below the top of the white covering strip.

Insulate the ducts against condensation between the unit and the ceiling mounting plate.

Mounting the ceiling mounting plate

1. Fasten the thread bars on the rafter frames or other frame structures, and screw the nuts (E) onto the bars.
2. Lift the ceiling mounting plate in place.
3. Push a rubber damper (F) and a washer (G) to each thread bar.
4. Adjust the nuts so that the ceiling mounting plate is level.
5. Shorten the lower ends of the thread bars so that they are no more than 5 mm below the nuts.

CAUTION
The ventilation unit is very heavy. Do not perform this procedure alone.

Installing the ventilation unit to the ceiling mounting plate

1. Install the ceiling mounting plate with M8 thread bars so that it is horizontally level.
   NOTE
   The end of the thread bars must be 5 mm or less below the fastening nut. Do not fasten the ceiling mounting plate too tight to the ceiling. Ensure that the sliding bars move and restore to their original position by pulling from the operating levers (A).
   The top edge of the white covering strip of the ceiling mounting plate can be installed against the ceiling. Alternatively, a concealed mounting method can be used, in which case the ceiling can be 30 mm below the top of the white covering strip.

2. Ensure that the insulation washers are in the outlet collars below the ceiling mounting plate.

3. Remove the door before installing the ventilation unit to the ceiling mounting plate.

4. Lift the ventilation unit close to the ceiling mounting plate and feed the cables and the connection box through the hole in the ceiling mounting plate on top of the ceiling.
   NOTE
   Remember to make a service door in the ceiling so that the cables and the connection box can be accessed. The distance between the service door and the ceiling mounting plate must be around 500 mm.
   Alternatively, the cables can be fed to the rear wall between the ceiling mounting plate and the ventilation unit. When the ventilation unit is lifted against the ceiling mounting plate, the unit locks in place. Where needed, guide the mounting hooks on the ceiling mounting plate (B) to the grooves on the side panels of the ventilation unit.
   There are operating levers (A) on the front bottom corners of the ceiling mounting plate. When the levers have been restored to the same level with the white covering strip
   of the ceiling mounting plate, the unit has been locked in place.

5. Where required, the unit can be detached from the ceiling mounting plate. Remove the door of the unit. Lift the unit slightly upwards and pull simultaneously from both operating levers (A) of the ceiling mounting plate to detach the unit from the ceiling mounting plate.

Attic floor penetration plate

• The attic floor penetration plate (D) is optional. When an attic floor penetration plate is used, the tightness of the vapour barrier has to be ensured.
• The attic floor penetration plate can be fastened on the finished rear wall. The minimum distance of the attic floor penetration plate from the finished side walls is 15 mm.

MAINTENANCE

BEFORE BEGINNING MAINTENANCE WORK
The safety switch (S) automatically turns off the power when the door of the unit is opened.

WARNING
Always disconnect the power plug before starting the ventilation unit maintenance.

There are two unit models, left- (L) and right-handed (R). The figure shows the right-handed model.

REPLACING THE 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:

• Coarse filter for supply air filters insects, heavy pollen and other relatively large foreign objects out of the outdoor air.
• Fine filter for supply air filters microscopic pollen and dust particles out of the supply air.
• Coarse filter for extract air filters the extract air and keeps the heat recovery cell clean.

The filter replacement interval depends on the ambient particle concentration. It is recommended that the filters be replaced every spring and autumn, or, at the very least, once a year.

To replace the filters:

1. Disconnect the ventilation unit from the mains electricity supply.

2. Open the door of the Vallox ventilation unit by undoing the finger screws.

3. Lift the door off.

4. Remove the old filters (A, B, C) and discard them.
   CAUTION: The door is heavy.

5. Install the new filters (A, B, C).

6. Close the door of the unit. Ensure that the safety switch catch of the door is touching the safety switch, allowing the unit to be turned on.

7. Plug the ventilation unit back into the mains. The filters have now been successfully replaced.

IMPORTANT
If the power cord is damaged, the manufacturer, its service representative or other person with similar qualifications must replace it to avoid danger.

NOTE
The service space in front of the ventilation unit must be at least 500 mm.

TIP
Using original Vallox filters ensures that the ventilation unit remains in top condition, giving the best results. To select and order filter packages, please go to: filters.vallox.com

CLEANING THE HEAT RECOVERY CELL
Check that the heat recovery cell is clean roughly once a year, or whenever the filters are being replaced. Clean by washing as required.

To check and clean the heat recovery cell:

1. Disconnect the ventilation unit from the mains electricity supply.

2. Open the door of the Vallox ventilation unit by undoing the finger screws.

3. Lift the door off.
   CAUTION: The door is heavy.

4. Remove the supply air filter (A).

5. Turn the upper support of the cell (B) to the upper position (anti-clockwise).

6. Remove the extract air filter (C).

7. Lift and pull the HR cell (D) out of the unit.

8. If the cell is dirty, clean it by immersing it in warm water, to which a small amount of a mild detergent has been added.

9. Rinse the cell clean with a water spray. Do not use a high-pressure cleaner.

10. When all the water has drained from between the layers, reassemble the ventilation unit as follows:

11. Ensure that the lower support (E) is in place against the knobs at the bottom of the unit.

12. Lift the HR cell in place.

13. Turn the upper support against the cell. Ensure that the upper support is properly nestled against the cell (remains upright).

14. Install the extract air filter (C) and the supply air filters (A) in place.

15. Close the door. Ensure that the safety switch catch of the door is touching the safety switch.

16. Plug the ventilation unit back into the mains.
    The heat recovery cell has now been checked and cleaned.

IMPORTANT
Handle the cell carefully! For example, do not lift the cell by the layers. The cell layers are very thin and easily damaged.

CONDENSING WATER
In the heating season, the extract air humidity condenses to water. In new buildings, the volume of condensing water can be high. 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 siphon or the condensing water outlet in the bottom pool are not clogged. To check this, pour some water into the pool. Clean as required.

NOTE
Some condensing water may have accumulated in the bottom pool of the unit; this is normal and requires no corrective action.

WARNING
Water must at all times be kept out of the electrical system.

CLEANING THE FANS
Check the cleanliness of the fans when servicing the filters and the heat recovery cell. Clean the fans as required.
You can clean the fan blades with compressed air (wear protective goggles) or by brushing them gently. Do not remove or move the fan blade balancing weights.

To clean the fan:

1. Disconnect the ventilation unit from the mains electricity supply.

2. Open the door of the Vallox ventilation unit by undoing the finger screws.

3. Lift the door off.
   CAUTION: The door is heavy.

4. Remove the supply air filters (A) and the extract air filter and turn the upper support of the cell (B) anti-clockwise against the ceiling. See chapters “Replacing the filters” and “Cleaning the heat recovery cell”.

5. Remove the support plate (F) by undoing the screws (E).

6. Push the wires of the fan and the rubber feedthrough (K/L) through the intermediate floor and to the bottom part of the unit.

7. Remove the plastic screws used to fasten the fans (I) (2 per fan). Remove the wing screws (J) (2 pcs) of the post-heating resistor (only when changing the supply air fan) and remove the cable of the resistor (G) from the connector.

8. Remove the fan from the unit by lowering it before turning the fan anti-clockwise, whilst tilting it. Remove the control grille by undoing the screws (4 pcs).

9. You can now clean the fan. Put the control grille (S) back in place after cleaning.

10. Reassemble in reverse order after cleaning. Once the fan has been installed, ensure that the rubber feedthroughs (M, K, L) are in place.

11. Close the door. Ensure that the safety switch catch of the door is touching the safety switch.

12. Plug the ventilation unit back into the mains.
    The fan has now been checked and cleaned.

Cleaning of the anemometer
The anemometer in the fan must be cleaned at least every three (3) years. It is recommended to use compressed air for the cleaning.

CAUTION
When using compressed air, the arms of the anemometer must not be allowed to rotate freely. This could damage the bearings.

EXTERNAL ELECTRICAL CONNECTION FOR CONTROLLING THE MLV DUCT RADIATOR

DUCT RADIATOR OPERATION

• Always follow first and foremost the connection diagram provided by the HVAC designer or heat pump manufacturer. Also read the duct radiator manual.
• The accompanying figure shows an example of the arrangement for connecting the heating/cooling radiator unit to the heat collection circuit.
• Connect the radiator output pipe to the heat collection circuit return pipe. Direct the fluid returning from the radiator unit to the heat collection circuit return pipe. If you know that there is a large loss of internal pressure inside the heat  pump, the heat pump should be bypassed. If this is done, the fluid circuit will come into operation when the heat pump comes to a halt. When this happens the pressure loss in the one-way bypass valve Y2 must be lower than the pressure loss in the heat pump.
• Heating: The pump starts when the outdoor air temperature drops below the winter limit value set at the factory (-5 °C).
• Cooling The supply air setpoint value for the active mode (for example, At home) controls the pump start-up. The pump starts when the supply air setting is below the temperature of the supply air that is blown into the apartment.
• The duct radiator can be installed in both the supply air duct and the outdoor air duct. If the radiator is installed in the outdoor air duct, it can be used for both preheating and cooling. If the radiator is installed in the supply air duct, it can be used for heating or for cooling only.

The duct radiator can be set to function either automatically or manually.

• Automatic – In summer, the supply air temperature will be maintained at the level specified in the temperature setting. In winter, the duct radiator will turn on, when the outdoor temperature falls below the winter setting.
• Manual – In summer, the duct radiator will turn on, when the outdoor temperature rises above the summer setting. In winter, the duct radiator will turn on, when the outdoor temperature falls below the winter setting.

To prevent the risk of condensation in the supply air duct, you can set the adjustment of the supply air limit to automatic or manual.

• Automatic – The supply air limit is adjusted automatically based on the dew point of the extracted air. When the supply air temperature falls too low, the duct radiator will turn off.
• Manual – The supply air limit can be set manually. When the supply air temperature falls to the set value, the duct radiator will turn off.

If an external sensor is in use, it is selected from the settings of the external sensor whether it is used to control the outdoor air duct radiator or the supply air duct radiator. The temperature of the external sensor can be read from the service menu: menu service menu > unit information page 5 ”External sensor”.

• NOTE: If the duct radiator is used in the supply air duct, it can only be used for cooling.

• NOTE : When used to control the outdoor air duct radiator, the external NTC sensor is installed in the outdoor air duct before the radiator. When used to control the supply air duct ra-diator, the external NTC sensor is installed after the radiator.

• NOTE:
  When selecting the relay (C), take account of the maximum allowed combined power supply (6W) of the circuit board in the external MV electrical box, if the relay power supply comes from the circuit board’s +24V connector.

• NOTE:
  Due to the risk of humidity damage, in a duct that has not been insulated for condensation, the supply air temperature must not fall below +16 … 20 °C.
