FAQ

Vallox MV ventilation units can also be controlled via the Internet. What software is needed for the phone or computer and how much does it cost?

When an MV model with MyVallox Control is connected to the MyVallox Home network, it can be controlled via the home network with a computer, tablet or phone. The service is browser-based and no other software is needed.

When the unit is connected to the Internet, you can register it with the MyVallox Cloude service and control it via the Internet with a computer, tablet or phone. Registration is free. You can control remotely all the same functions of the units as with the controller.

For instructions on registration, see the manual of the unit and Vallox WebHelp.

How do you switch heat recovery bypass on in MV units in summer?

Heat recovery bypass is automatic in MV models. When outdoor air is warmer than the setpoint for supply air temperature, the unit switches bypass on. If outdoor air is warmer than the air going out from the dwelling, the unit uses cool recovery: it aims at cooling down the warm outdoor air with the coolness of extract air. The status of heat recovery and bypass is shown at the controller.

There is no separate summer/winter switch, but if you want to use the cooling function in summer, you have to set it: Special settings - Sensor settings - °C adjustment mode - Cooling. With this setting, ventilation is boosted automatically when supply air can be used to cool the dwelling.

Does the fireplace switch stop the extract air fan altogether?

Not necessarily. You can choose in the fireplace profile settings of an MV unit if extract air flow is reduced and/or if supply air flow is increased, and you can also specify the amount of decrease or increase. You can freely choose the time period for the fireplace function. It is also possible to implement the fireplace function with a separate switch (push button).

The fireplace always needs to have a combustion air duct that comes directly from the outside to a location recommended by the fireplace manufacturer.

Can MV models compensate for the negative pressure caused by a cooker hood or a central vacuum cleaner?

Partly, yes.

The extract air flow of a cooker hood or a central vacuum cleaner can be higher than ventilation in the whole dwelling, so it cannot necessarily be wholly compensated for with a ventilation unit.

Compensation requires a contact output (switching contacts) from the cooker hood, central vacuum cleaner or a pressure difference switch connected to them. The control voltage received from the MV unit is brought through these contacts back to the digital input. At the controller of the MV unit, choose Self-programmed input as the setting for this digital input. After that, choose the desired power for the supply and extract fans in the self-programmed input settings.

What is the difference between setup settings and user settings in an MV unit?

The fan, temperature and other settings made during setup are automatically saved as setup settings. Changes made later are automatically saved as user settings. Also changes made later on can be manually saved as setup settings. You can restore both setup and user settings at the controller or via remote control.

Note! When the setup settings are restored, they also overwrite the user settings. Factory settings reset erases both the setup and the user settings from the memory of the unit.

If a cooker hood is connected to the ventilation unit in the dwelling, which kind of cooker hood can be used to control an MV unit?

Method 1:

Automatic cooker hood boosting with a self-programmed digital input

With the cooker hood boosting function, the fan speed of the ventilation unit increases when the flap of the cooker hood is opened.

Automatic cooker hood boosting can be implemented by bringing a control voltage of 24 V from the timer of the flap of the cooker hood, such as Vallox KTXA, to the digital input (1 or 2). The contacts of the timer of the cooker hood close when the flap is opened. In this case, Self-programmed input has to be chosen as the function for the digital input. In the settings for the Self-programmed input, switch the timer off, set the desired power for the supply and extract air fans as a percentage as well as the desired supply air temperature. These can be different from the setpoints of the other  profiles. The supply/extract ratio can also be different from other profiles if you wish to compensate for the increase in the extract air flow caused by the opening of the flap of the cooker hood.

Method 2:

Controlling fan speed at the cooker hood

You can control the fan speed of an MV unit (away/home/boost) with any cooker hood that gives a voltage signal (0-10 VDC), such as Vallox PTXP MC SlimLine.

Note! You cannot increase fan speed at the cooker hood higher than the Boost profile.

The MV unit is controlled in parallel with the MyValloxControl controller supplied with the unit. The latest command is always the one that stays in force.

In both cases, all the functions of the MV unit are also controlled at the MyValloxControl controller

Is it possible to use a cooling or preheating radiator connected to ground heat in MV models?

There is no MLV radiator connected to the ground collector available for MV models, but a separate MLV radiator can be installed in the outdoor air duct of an MV model. The pump and the solenoid valve of the cooling and preheating system can be controlled from the connection box of the MV unit.

It is possible to use a control voltage of 24 V to control a contactor that starts the pump and opens the solenoid valve when needed. The cooling function starts automatically when outdoor temperature rises higher than the setpoint temperature for the air blown into the dwelling. The preheating function start when outdoor temperature goes down to a few minus degrees.

Note! In the special settings, choose the following as the relay function: Control of external liquid radiator.

There is no separate summer/winter switch, but if you want to use the cooling function in summer, you have to set it: Special settings - Sensor settings - °C adjustment mode - Cooling. With this setting, ventilation is boosted automatically when supply air can be used to cool the dwelling.

What additional devices are needed for connecting Vallox MV models to the Modbus bus?

Vallox MV models can be connected to the Modbus bus directly, without a separate adapter.
