This transfers up to 88 % of the heat energy. The heat exchanger is heated in 70 seconds and the ventilation system automatically switches to supply air mode.CYCLE II. The fresh outdoor air flows over the ceramic heat exchanger and extracts the stored heat from it until the room temperature is reached. In 70 seconds, the heat exchanger is cooled and the ventilation system switches back to extract air mode. The cycle starts again.The switchover to supply and exhaust air mode takes place every 70 seconds. CONTROL AND OPERATING TYPES OF TWINFRESH COMFO   For ease of use and simple operation, TwinFresh Comfo ventilation systems are equipped with a remote control. If several ventilation systems are connected to a single network of ventilation systems, only the first ventilation system will receive the signal from the remote control. The manually operated operating switches for basic operating modes on the housing of the models TwinFresh Comfo make the operating control of the systems even more convenient and practical.   AN EXAMPLE OF THE L&R SYSTEM BASED ON TWINFRESH   For a ventilation system based on TwinFresh install a ventilation system in every room. Mount two or more ventilation systems in larger rooms. For controlled ventilation of living spaces, we recommend installing the ventilation systems in pairs. Set some ventilation units to supply air mode and other ventilation units to extract air mode. The TwinFresh  ventilation systems can be used individually. If each lighting system is operated separately, the operating mode of each individual lighting system can be set individually. The air flows between rooms through doorways and the hallway, creating air circulation in the house. Thanks to the ventilation system with energy recovery based on the TwinFresh ventilation system, operating costs for heating and air conditioning are significantly reduced. To create highly efficient ventilation in your home, we also recommend the intelligent VENTS iFan Fans can be installed in the kitchen or bathroom. The exhaust air is then automatically extracted after the humidity or motion sensor is activated An example of the ventilation system based on TwinFresh Comfo RB-50 TWINFRESH CONSTRUCTION   Fan unit The ventilation systems TwinFresh Comfo are equipped with an automatic shutter.
