The Systemair SAVE VTR 300/B is a ventilation unit designed for residential applications, providing balanced ventilation with heat recovery. It is intended to operate continuously, ensuring a healthy indoor climate by supplying fresh outdoor air and extracting stale indoor air, while minimizing energy loss through its heat exchanger.
Function Description
The SAVE VTR 300/B is a mechanical ventilation unit with heat recovery, designed to provide a continuous supply of fresh, filtered air to a building while recovering heat from the extracted stale air. This process helps maintain a comfortable indoor temperature and reduces heating costs. The unit features a rotational heat exchanger, which is generally efficient in dry conditions. However, in humid environments, a condensation drainage system might be necessary, which is available as an accessory. The unit can be configured for either left-hand or right-hand connections, allowing flexibility in installation based on the building's ducting layout. It supports various airflow control types, including manual RPM adjustment, and allows for setting different airflow levels (minimum, high, and normal) for both supply and extract air. The integrated re-heater further ensures that the supplied air is at a comfortable temperature.

Usage Features
- Continuous Operation: The unit is designed for continuous operation to maintain optimal indoor air quality. If the unit is intended to be stopped manually or via a calendar function, air-tight dampers at extract and supply air ducts are recommended to prevent condensation and cold air ingress.
- Airflow Control: The unit allows for setting different airflow levels (minimum, high, normal) for both supply and extract air, with adjustable fan speeds.
- Language Selection: The startup wizard offers multiple language options, including English, Čeština, Dansk, Deutsch, Eesti, Suomi, and Français.
- Date and Time Setting: Users can set the current date and time during the initial setup.
- Flexible Connections: Available in left-hand and right-hand models, allowing the supply air connection panel to be situated on the desired side.
- Cooker Hood Air Connection: Includes a dedicated connection for cooker hood air, ensuring efficient removal of cooking fumes.
- Condensation Management: While generally not needed for rotational heat exchangers in dry conditions, a condensation drainage accessory is available for humid environments. Proper installation of the drainage pipe with a water trap is crucial.
- Outdoor Air Intake Recommendation: For optimal performance and air quality, the outdoor air intake should ideally be located on the northern or eastern side of the building, away from pollution sources like exhaust vents from kitchen ventilators, central vacuum systems, waste water drainage, and traffic.
Maintenance Features
- Easy Access for Maintenance: The unit requires regular maintenance, and its design ensures easy access to the inspection door for servicing. Sufficient free space should be left around the unit for opening the door and removing main components.
- Filter Mounting: Filters must be mounted before starting the unit to ensure proper operation and air quality.
- Commissioning Record: A commissioning record must be completed during the initial startup and for any subsequent changes, ensuring proper documentation of settings and performance.
- Safety During Maintenance: All electrical connections and maintenance work must be carried out by authorized installers, with the mains supply disconnected. Protective gloves are recommended due to sharp edges.
- Disposal and Recycling: The product is compliant with the European WEEE Directive. Users are instructed to follow local rules and regulations for disposal and recycling. Packaging materials are recyclable and can be reused.
