As Simple As 1, 2, 3
1. When all zones are calling, all zone dampers will be open.
2. As zones begin to satisfy, their dampers go closed and the system static pressure will start to rise. This will send a small amount of additional air into the zones that are still calling.
3. Only when the supply static pressure reaches approximately 0.3" WC will the barometric blade of the damper begin to modulate open. This will send a small amount of air to the zone(s) that are not calling.
