  • Page 5: Customer Information

    Please pay attention to the safety instructions! Product Description The devices in the aerosmart series are compact units which consist of a ventilation module with heat recovery, a domestic water storage tank and a heat pump. The unit is used to heat the supply air and the domestic water.

  • Page 6: Operation

    Operation The unit is controlled, managed and operated via a micro-processor controller on the unit and a room operating panel. Two types of room operating panels are available: • Analogue room operating panel with heating mode • Digital room operating panel If the analogue room operating panel is used, the basic settings must be made on the compact unit (micro-processor controller) during commissioning.

  • Page 7: Main Display

    Main Display The main display shows the time and date, the current operating mode and the current values for the room, set-point and actual temperature. 12:11 DI. 09/12/03 AUTOMATIK Akt.

  • Page 8: Analogue Room Operating Panel With Heating Mode

    Analogue Room Operating Panel with Heating Mode Use this room operating panel to set the room temperature and activate the special 'Party' mode. The LED indicator lights show if the heating is activated and if a fi lter change or fault is pending.
  • Page 9 A handy hint for greater system effi ciency If possible, fi nd your desired temperature at the start of the heating period. The system works most effi ciently if the set-point temperature is set once and then left unchanged. Regularly changing this setting uses the top up heater in the room more than necessary.

    Digital Room Operating Panel The digital room operating panel on the ventilation device operates at the same time as the micro-processor controller. The menu navigation, buttons and scope of operation are identical. Setting the Room Temperature Press the 'ESC' button until the main display appears. 12:11 DI.
  • Page 11 Special 'Party' Mode The ventilation is set to fan level 3 for a specifi c period. Once this period has passed, the fan level automatically returns to the currently set level. On delivery of the system, the default period is 60 minutes, but this can be adjusted in the technician level. Press 'Esc' to go from the main display to the main menu.

  • Page 12: Maintenance

    Maintenance System maintenance by users is mainly limited to regularly changing the coarse particle fi lters in the ventilation module and the fi ne particle air fi lter in the outside air unit. The operating unit provides regular fi lter change notifi cations as the system operating hours are counted in the background.
