When setting my zone percentage (%) with YourZone, I sometimes see a “^” symbol next to it. What does this mean?

For system safety, the unit always maintains airflow equivalent to at least one fully open zone (100% total across all zones).

If a “^” appears, it means the total percentage across all zones doesn’t equal 100%. Therefore, the zone you adjusted won’t be at the exact percentage shown.

To correct this, increase the percentage of another zone until the total equals 100% and the “^” symbol disappears.
