Local heat and moisture recovery ventilator Micra 110 V1 ERV

Decentralized ventilation with heat and moisture recovery

The VENTS Micra 110 V1 ERV local recuperator is a solution for a single room where you want fresh air without a classic central ventilation system. This model combines the built-in, flush-mounted design of version V1 and an ERV enthalpy exchanger, so it differs from other Micra 110 units in that it returns both heat and moisture. This is especially useful in renovations and refurbishments, when installing branched ductwork is impractical, while the result is something you want to feel every day in a more stable and comfortable living environment.

Built-in (flush-mounted) installation

Version V1 is intended for installation in a wall opening, so the unit is neatly concealed within the structure and does not act as a surface-mounted accessory. Standard connection is based on a 100 mm duct with four top connections for supply and exhaust on the indoor and outdoor side. As an alternative, the flush-mounted housing can also be configured with two 75 mm semi-rigid ducts, which makes it easier to adapt to different installation conditions.

Enthalpy exchanger - moisture and heat together

In the ERV version, the exchanger core returns not only heat, but also part of the moisture from the exhaust air. This is the key difference compared with the standard HRV models in the Micra 110 family, which mainly return heat. The built-in humidity sensor helps ensure more thoughtful operation, so the indoor climate remains better balanced even in periods when classic ventilation by opening windows could dry out the room too much.

Main advantages

• Heat and moisture together
  The enthalpy exchanger preserves part of the moisture and heat, making the air more pleasant and less dry than with standard heat-recovery ventilation.
• Up to 85% heat recovery at speed I
  At the lowest setting, efficiency is highest, which means effective ventilation and lower heat losses during the heating season.
• Only 10 dB(A) at speed I
  Quiet operation makes it suitable for use in a bedroom, study, or children's room, where low noise is especially important.
• Automatic air dampers
  When switched off, the supply and exhaust sides close, helping prevent unwanted drafts through the unit.
• Easy control on the unit itself
  The built-in control panel allows switching on, selecting three speeds, summer bypass, and displaying filter maintenance and alarms, without the need for an app or smartphone.

Operation and control

The unit functions as a bidirectional local fan for supply and exhaust air in one room. Operation is simple and is carried out via the built-in side control panel, where you select on/off, one of the three speeds, or switch to summer heat-bypass mode. The panel also includes a filter maintenance display and an alarm signal, so you have a basic overview of the device status directly at the point of use. Remote control and a wired control panel are available as accessories.

Technical specifications

Energy efficiency (EU Ecodesign)

The official energy data depends on the climate zone, so it is not correct to describe this model with a single class. For the cold climate zone, SEC is -76.6 kWh/(m2.a) and energy class A+, for the average climate zone SEC is -39.5 kWh/(m2.a) and class A, and for the warm climate zone SEC is -15.6 kWh/(m2.a) and class E. Annual electricity consumption is 764 kWh/a in cold, 227 kWh/a in average, and 182 kWh/a in warm climate. Annual heat savings are 8695 kWh/a in cold, 4445 kWh/a in average, and 2010 kWh/a in warm climate. These are regulatory data that help realistically assess operating costs and the unit's efficiency.

Frequently asked questions

What does V1 mean and what does ERV mean?
V1 indicates the built-in or flush-mounted version installed in a wall opening. ERV means an enthalpy exchanger that returns heat and moisture together.

How does this model differ from the standard Micra 110 HRV?
The main difference is in the core: the ERV version also returns moisture, while the classic HRV models in the same family mainly return heat.

Does it need WiFi or an app to operate?
No. Control is handled via the built-in side panel, and a remote control and wired control panel are also available as separate accessories.

How quiet is it when used in a bedroom at night?
At speed I, the sound pressure level at 3 m is 10 dB(A), and at 1 m it is 20 dB(A), so it is also suitable for more sensitive living spaces.

Is it possible to choose a finer filter?
Yes, the standard supply filter G4 can be upgraded with the optional ePM1 65 % / F7 filter for better supply air filtration.

Conclusion

VENTS Micra 110 V1 ERV is a thoughtful choice for anyone who wants quiet and efficient ventilation with heat and moisture recovery in a single room. The flush-mounted version, enthalpy exchanger, and simple local control make it especially attractive for renovations where a good indoor climate is important without a complicated duct system.
