Control using the buttons on the front panel or remote control. Closed air shutters prevent drafts when the ventilator is switched off. Clean and fresh air 24 hours a day.
Energy efficient DC fan is a recipe for silence and energy saving. The simple operation logic of the regenerator will provide clean and fresh air in your house. Manual control has never been so easy!

To provide convenient and simple control the TwinFresh Comfo units are completed with a remote control.

Operation modes:

 - Night mode 

The integrated light sensor sends a signal to switch the ventilator to low speed mode.

 - Speed switching   

 - Passive air supply 

The automatic shutters are opened but the fans are off in this mode.

 - Air supply 

In this mode all ventilators will operate in supply mode irrespective of the maximum air supply setting.

 - Ventilation 

All the ventilators in the network operate in permanent air extract or air supply mode. To ensure balanced ventilation it is advisable to set one half of the ventilators to air supply mode and the other part of the ventilators to air extract mode.

 - Ventilation with heat recovery 

 - Humidity control mode selection   

Simple mounting – you need only to mount it, plug into a socket and use! High efficiency – up to 85%.
The unit properly operates at temperature range up to -20 °C. Integrated humidity sensor for the automated unit operation.
Can be mounted inside a prepared hole (from ∅ 100 mm) in a wall. Simple ventilator control.
Automatic drafts shutoff by shutters when the ventilator is off. Noise at the level of subdued conversation (22-33 dBA).
Ventilation of premises with the area of about 15 m2 (the area is approximate and depends on the ventilation standards in your country). Night mode. The ventilator switches to low speed in the dark time of the day (by a light sensor).
