## Summary description

Vaillant recoVAIR 260/4 is a mechanical ventilation unit designed for balanced supply and exhaust air with a counterflow-cross heat exchanger. The unit features a bypass function and a built-in digital controller for setting ventilation modes and temperatures. It is intended for residential or light commercial ventilation to improve indoor air quality and recover heat from exhaust air.

## Long description

Vaillant recoVAIR 260/4 with counterflow-cross heat exchanger, bypass and digital controller is a mechanical balanced ventilation unit designed to provide controlled supply and exhaust air while recovering heat from the outgoing airflow. The compact unit integrates a counterflow-cross heat exchanger to improve thermal recovery efficiency and a bypass function that allows reduced heat recovery during warmer periods. A built-in digital controller enables mode selection and temperature-related adjustments to match residential or light commercial ventilation needs.
Advantages
The unit offers balanced supply and extract ventilation with integrated heat recovery to reduce energy losses and support a stable indoor climate. The counterflow-cross heat exchanger increases recovery efficiency while maintaining compact dimensions. The bypass function provides flexibility for free cooling when outdoor conditions permit. The digital controller centralizes control of ventilation modes and settings, simplifying commissioning and everyday operation.
Suitable for
Ventilating apartments and houses with mechanical balanced ventilation requirements
Small offices and light commercial premises requiring controlled indoor air quality
Retrofit installations where space is limited and heat recovery is desired
Key specifications
Balanced supply and exhaust ventilation with heat recovery
Counterflow-cross heat exchanger for improved thermal efficiency

How to use
Install the recoVAIR 260/4 according to the manufacturer's layout recommendations, ensuring appropriate duct connections for supply, extract, outdoor and exhaust air. Connect the unit to the building electrical supply and configure the digital controller to select ventilation modes and set temperature-related parameters. During operation, the unit continuously exchanges indoor and outdoor air while the heat exchanger transfers heat from exhaust to supply air; use the bypass when free cooling is required or when heat recovery should be reduced. Routine checks of filters and periodic maintenance of the heat exchanger and fans keep performance within expected parameters.
Usage recommendations
Use appropriate filter classes compatible with the unit and replace filters at the intervals recommended by Vaillant. Schedule periodic inspections of ductwork and fan assemblies to maintain airflow balance and heat recovery efficiency. Configure the digital controller to suit occupancy patterns to optimize indoor air quality and energy use.
