INTRODUCTION

IMPORTANT

Apartment-specific 

ventilation units allows 

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 centre. 

In order to ensure that 

the indoor air presents 

no harm to health and 

remains optimal also 

for the structures of the 

building, 

ventilation 

must be kept on 

without disruptions. 

It is recommended 

that ventilation be 

left 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. 

NOTE

For the MyVallox 

Cloud/Home 

instructions, please go

ValloxMV/ENG/help/

webhelp

IMPORTANT

Prolonged overpressure 

can result in damage 

to the structures of the 

building.

VENTILATION UNIT CONTROL 

Ventilation unit control options.

Operation of the Vallox ventilation unit can be controlled by the 

following means:

•  Through the My Vallox 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. 

Filter reminder

The unit reminds the user of the need to change the filters through 

the MyVallox Control panel and the MyVallox Home/Cloud user 

interface, as well as by changing the relay status, if a signal light has 

been connected to the relay connectors of the unit.

The filter reminder can be acknowledged:

•  From the MyVallox Control panel

•  From the MyVallox Home/Cloud user interface

•  From the Vallox Delico PTD EC and Vallox Capto PTC EC 

control hoods 

— Damper closed, then open-closed-open-closed. 

Press at a less than 1 second interval.

Ventilation unit setup without a MyVallox 

Control panel

The ventilation unit setup can also be completed without a MyVallox 

Control panel. For instructions, please go to 

https://vallox.techmanuals.info/ValloxMV/ENG/help/webhelp
See 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.
