USER MANUAL<\/a><\/p>\n

Ventilation unit with heat exchanger – wall-mounted design, counterflow plate heat exchanger, EC motor, up to 40\u00b0C, IPX2, filter, variable speed.<\/div>\n
    \n
  • Easy installation: A mounting bracket is included to make it easy to hang the device on the wall.<\/li>\n
  • Simplified electrical connection: The device is supplied with a cord.<\/li>\n
  • An ISO coarse 60% (G4) filter that can be easily removed for cleaning. The unit can also be optionally equipped with an ISO ePM1 60% (F7) filter on the intake side. <\/li>\n
  • Integrated automatic bypass for cooling during the summer season.<\/li>\n
  • Automatic freeze protection to prevent freezing on the suction side of the heat exchanger.<\/li>\n
  • Two connections for condensate drainage make it easy to change the unit’s configuration and monitor condensate formation in both winter and summer.<\/li>\n
  • The device’s left\/right configuration can be adjusted on the screen to ensure installation flexibility.<\/li>\n<\/ul>\n<\/div>\n

    A central recycling unit suitable for vertical wall mounting.<\/p>\n<\/div>\n

    Function<\/h3>\n
    \n

    The fan’s outer housing is made of powder-coated galvanized steel for a durable and sturdy construction. The unit is white (RAL 9010). <\/p>\n

    The internal EPP (expanded polypropylene) structure reduces noise emissions and ensures maximum airtightness and thermal insulation.<\/p>\n

    Standard EC motors with external rotors for energy efficiency. Equipped with integrated thermal protection and mounted on sealed ball bearings for the entire service life. Long service life. <\/p>\n

    A dynamically balanced, backward-curved centrifugal impeller, driven directly by a motor, ensures a smooth airflow through the unit.<\/p>\n

    A highly efficient counterflow heat exchanger for maximizing heat recovery.<\/p>\n

    The device is equipped with a multifunctional LCD screen (CTRL-DSP) to ensure automatic control and convenience, and offers:<\/p>\n

    \u2022 3 speeds (adjustable).<\/p>\n

    \u2022 Vacation mode.<\/p>\n

    \u2022 Night mode.<\/p>\n

    \u2022 Weekly timer.<\/p>\n

    \u2022 Pass-through mode\u2014without heat recovery, e.g., in the summer.<\/p>\n

    \u2022 Airflow equalization.<\/p>\n

    \u2022 Filter replacement indicator and fan malfunction.<\/p>\n

    \u2022 Work hours counter.<\/p>\n

    \u2022 Saving and loading settings.<\/p>\n

    \u2022 Compatible with outdoor sensors (SEN-HY, SEN-PIR).<\/p>\n

    \u2022 ModBus interface.<\/p>\n

    \u2022 Connection with remote preheating or post-heating.<\/p>\n

    \u2022 Connection to an external water supply for heating.<\/p>\n

    \u2022 Left or right version (air connection).<\/p>\n<\/div>\n
