This symbol appears when the actual fan speed deviates from the standard or normally set speed, possibly due to specific operating conditions or manual adjustments.
Click steps to track your progress.
Check settings related to fan speed in menus like 5.1.5 ('fan sp. exhaust air') or 5.1.6 ('fan sp. supply air').
Review any accessory settings that might affect fan speed, such as those related to exhaust/supply air modules.
If the fan speed change is unexpected, investigate the operating conditions or consult advanced settings.
