    Figure 1. Boost mode information CFi/MV

    This screen shows the following information:

    • Supply air — Indicates the temperature of the air blown into the building and its set value (in brackets), if the supply air is warmer than the set value.

    • Extract (CFi) — Indicates the current extract air flow (l/s or m3/h). The extract air flow setting is determined automatically based on the supply air flow, and the user cannot adjust it.
    • Supply (CFi) — Indicates the current supply air flow (l/s or m3/h). If the ventilation unit is automatically boosting the air flow in response to an increased humidity or carbon dioxide level or a need for cooling, the actual air flow can be higher than the set value. The set value is shown in brackets.
    • Outdoor air (MV) — Indicates the outdoor temperature.
    • Fan speed (MV) — Indicates the fan speed. If the automatic fan speed boost is active, the set value is shown in brackets, followed by the real fan speed.

    • Cell status — The ventilation unit has the following HR cell modes:

      • Heat recovery — The HR cell heats the air flowing in from outdoors with extract air.
      • Cold recovery — The HR cell cools the air flowing in from outdoors with extract air when the temperature of the air that is extracted from the apartment is two degrees lower than the outdoor temperature.
      • Bypass — The inflowing air bypasses the HR cell.
      • HR cell defrost in progress — The HR cell is being defrosted.
  4. Select Right arrow. The second mode information screen opens:

    This screen shows the following information:

    • Humidity — Indicates the highest relative humidity value measured by the sensors.
    • Carbon dioxide — Indicates the highest carbon dioxide value measured by the sensors.
    • Replace filters — Indicates the next recommended filter replacement date.
    • Time in operation — Indicates for how long the unit has been running.
  5. Select Right arrow. The third mode information screen opens.
