- The zone damper controller monitors supply air temperature.
- When the zone temperature rises above the Occupied Cooling Setpoint, the primary air damper modulates open from Damper Cooling Min Position to Damper Max Position.
- When the zone temperature drops below the Occupied Heating Setpoint, the primary air damper modulates from Damper Heating Min Position to Damper Max Position.
- If the supply air does not satisfy the cooling or heating requirements, the primary air damper remains at the Damper Satisfied Min Position.
