Setting the maximum air flow

You can measure the ventilation unit’s maximum air flow in the duct system in use. The test takes no longer than one minute and it is not mandatory. To skip the test, select Next. If the test is skipped, the default maximum air flow value is used.

After the test, the measured maximum supply and extract air flows are displayed. If the maximum air flow is low, the supply or extract air flow may be blocked. In that case, check the ventilation unit and ducts for obstructions.
