Local heat recovery unit Micra 200 E ERV WiFi

Smart ventilation with heat and moisture recovery

VENTS Micra 200 E ERV WiFi is a decentralized, through-wall ventilation unit for a single room that returns not only heat but also moisture. This means a more comfortable indoor climate than with conventional units that recover heat only, while also helping maintain efficient ventilation without unnecessary losses.

Main advantages

• ERV heat and moisture exchanger
  The unit with an enthalpy plate counterflow exchanger transfers heat and moisture between the supply and exhaust air, so the air in the room is less dried out.
• WiFi control via app
  Settings can be adjusted remotely: on/off, all 5 speed levels, recovery mode, summer bypass, electric afterheating, as well as filter maintenance warnings and alarm.
• 5 airflow levels for flexible operation
  Airflow can be selected according to the needs of the room, up to a maximum of 200 m3/h, while at lower levels the unit maintains very good heat recovery efficiency.
• Built-in 650 W electric preheater
  The preheater protects the core from freezing and helps ensure reliable operation in colder conditions and at low outdoor temperatures.
• Quiet start and discreet operation
  At the lowest speed it reaches only 12 dB(A) sound pressure at 3 m, so the unit can operate in the background without disturbing everyday life.

Smart control

Control is via a dedicated WiFi app for iOS and Android, where you can turn the unit on or off, choose between five speeds, and switch between recovery mode and automatic summer bypass. Electric afterheating control is also available, allowing more flexible use throughout the year. The app displays a filter service warning and alarm indicator, and for even more precise ventilation, sensors CO2 and/or humidity are available as optional accessories for demand-controlled ventilation.

Installation

The unit is intended for external through-wall installation and is suitable for walls with a thickness of approximately up to 400–500 mm. Connection is via a 100 mm diameter duct, and the package includes the MK Micra 200 mounting kit with 2 plastic pipes, an external grille box and a cardboard drilling template. The mounting kit is available in chrome or white, and for more demanding installations there is also an additional NB Micra 200 external box.

Frequently asked questions

How is the unit used in everyday life?
It is controlled via the app, where you turn the unit on or off, select the speed, and if needed enable recovery mode or summer bypass.

Does it recover only heat or also moisture?
This is an ERV unit, so it recovers both heat and moisture. This is especially useful in winter, when indoor air is often too dry.

Is it suitable for a bedroom or living room?
At the lowest level it reaches 12 dB(A) sound pressure at 3 m, so it can be very discreet in the background. The final speed choice of course depends on the needs of the room.

Is it reliable even in colder winters?
Yes. The built-in 650 W electric preheater helps protect the core from freezing and supports stable operation in colder outdoor air.

Conclusion

VENTS Micra 200 E ERV WiFi combines local ventilation, heat and moisture recovery, and convenient app control. If you are looking for an efficient solution for a single room with precise airflow adjustment and reliable winter operation, this is a very convincing choice.
