6. The box may not have been balanced correctly. Contact your local Siemens
Industry representative.
7. The air velocity sensor may need calibration. Set CAL AIR to YES to run the
calibration sequence. When CAL AIR returns to NO, indicating that the sequence is
finished, run the checkout procedure again to see whether the problem has been
corrected.
Controller could not reach CLG FLOW MAX or above—CHK STATUS =
16
1. Check for the problems described immediately above for CLG FLOW MIN.
2. The box may be starved for air, because either the central air-handling unit is off or
there is low duct static.
Controller did not read low (zero) flow when damper closed—CHK
STATUS = 32
1. Check for the problems described above for CLG FLOW MIN.
2. The damper shaft may not be secured correctly to the actuator so that when the
actuator is fully closed, the damper does not completely shut off airflow.
3. Airflow calibration (at zero) may need to be performed ensuring the damper is fully
closed and/or the air handling unit is off.
