TwinFresh Style Wi-Fi decentralized heat recovery ventilator

What is VENTS TwinFresh Style Wi-Fi?

The VENTS TwinFresh Style Wi-Fi local heat-recovery ventilator is a decentralized single-room ventilation system with a regenerative ceramic heat exchanger and built-in Wi-Fi control. It is designed for ventilating individual rooms where a central ventilation system is difficult to install, as it requires only one wall opening and connection to a 160 mm duct for installation.

It is a practical solution for renovations and retrofits, as it enables air exchange without a complex duct network while also helping to retain heat in the room. The unit operates at three speeds and also supports linking multiple devices into one Wi-Fi system for coordinated operation in several rooms.

Main advantages

• Wi-Fi control via smartphone
  You can also control the device remotely via the app, which is convenient when you are away from home or want to check the ventilation status quickly and easily.
• Automatic response to humidity
  The built-in relative humidity sensor enables automatic operation according to the room’s needs, so ventilation is better adapted to actual conditions.
• Quiet and comfortable operation
  When switched off, the automatic shut-off dam closes, so airflow stops without unwanted drafts.
• Flexible operating modes
  Available modes include automatic mode, heat recovery, ventilation only or exhaust only, as well as additional modes such as night mode, weekly schedule and party mode.
• Filtration upgrade option
  The standard G3 filter can be upgraded if needed with an additional G4 or F7 filter, with F7 providing finer filtration but also a lower maximum airflow.

Operation and control

The VENTS TwinFresh Style Wi-Fi local heat-recovery ventilator is designed for comfortable everyday use. You can control it directly via the built-in control panel on the housing, with the infrared remote control, or via a smartphone through the Wi-Fi connection. The built-in module supports the IEEE 802.11 b/g/n standard in the 2.4 GHz band, and the network operates via DHCP and WPA/WPA2 protection.

The unit supports automatic, heat-recovery and ventilation operation, as well as speed switching and standby. In heat-recovery mode, the device alternates between supply and exhaust air approximately every 70 seconds, which allows heat from the exhaust air to be transferred back into the fresh air entering the room. In practice, this is very useful in bedrooms, offices, children's rooms and other smaller spaces where you want continuous air exchange without complicated alterations to the room.

For more tailored use, there is a weekly schedule, night mode and party mode, and the housing also includes a filter maintenance indicator. The built-in relative humidity sensor enables automatic operation based on the room humidity, and an external input for a CO2/relay sensor is also supported.

Technical specifications

Energy efficiency

For this model, two different heat recovery efficiency values are stated. The manufacturer's top-line claim says up to 90%, while the Ecodesign calculation states 82%. For the user, this means the device helps reduce heat losses during ventilation, while it is important to distinguish between the marketing maximum value and the officially calculated value used for energy assessment.

Frequently asked questions

Can I control the device when I am away from home?
Yes. The device has a built-in Wi-Fi module and can be controlled via a smartphone, and it also supports a remote control and the built-in control panel.

Do I need a central ventilation system?
No. VENTS TwinFresh Style Wi-Fi is a decentralized local heat-recovery ventilator that operates independently through one wall opening and does not require central ductwork.

Can I connect multiple units together?
Yes. Multiple units can be connected into one Wi-Fi master/slave network for coordinated and balanced ventilation of multiple rooms.

Can the filter be upgraded?
Yes. The basic G3 filter is installed as standard, and if needed an upgrade to G4 or F7 is also available, with F7 providing finer filtration.

Conclusion

The VENTS TwinFresh Style Wi-Fi local heat-recovery ventilator is a well-considered choice for anyone who wants efficient ventilation of a single room with heat recovery, easy installation and modern Wi-Fi control. It combines independent operation, smart functions and flexible operating modes in one compact solution.
