    UNIVERSAL EFFICIENT USER-FRIENDLY
    Many units can be connected to one network. The ventilator can operate in a passive supply mode: the air shutters are open providing a natural air flow. The design of the unit allows easy maintenance of the ventilator.
         
    The humidity threshold in the room can be controlled by choosing one of three modes on the remote control. Night mode
    The ventilator switches to the first speed in the dark time of the day.    		 Easy mounting of the mounting plate by means of magnets.
         
    EASY CONTROL    
    The TwinFresh Comfo series
    ventilators are equipped
    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 

    In this mode the shutters are open, but the fan does not operate.

     - 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 at the stage of installation 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   


    The ventilators can be connected into one network for centralized control.
    The signals from the control panel and the remote control, as well as
    from the humidity sensor, are received only by the master (main) ventilator.

      
    ADVANTAGES    
    Maximum ease of installation – mount into the wall, plug in and use. High efficiency – up to 90 %.
    Normal operation of the unit at temperatures down to -20 °C (-30 °C with a hood for a cold climate). Built-in humidity sensor for automation of unit operation.
    Connecting a large number of units to the network using control cables. Control via remote control or buttons on the unit casing.
    Automatic blocking off draughts by means of louver shutters when the unit is switched off. Noise from 13 to 34 dBA.
    Ventilation of premises with the area of about 40 m2 (the area is approximate and depends on the ventilation standards in your country). Higher degree of supply air purification can be achieved with an F7 filter.
        Electrical fuse on the board for increased electrical safety.
    OPERATION IN A NETWORK    
    • Any number of ventilators may be connected into one network.
    • Control is carried out through the first ventilator.
