VAV VV550 Controller Programming and Operation
commissioning test sequence starts. The fields are updated with the results as the sequence
progresses. The data is held until the next auto-commissioning test.
If an auto-commission command is received in the middle of an auto-commissioning cycle the
auto-commissioning sequence restarts. If an auto-commission command is received during
calibration, calibration aborts and restarts after auto-commissioning finishes. If an abort auto-
commission command is received during the calibration portion of the primary air valve test, it is
honored after the air valve calibration finishes.
The mode field of reported unit status reports TEST when the controller is in the auto-
commissioning sequence.

(a)
1. Turn off fan and reheat.
2. Close air valve and modulating water valve (if present).
3. Calibrate the airflow sensor.
4. Open the air valve to 40% of the configured maximum airflow. Record the position of the air valve.
5. Open the air valve to 100% of the configured maximum airflow. Record the position of the air valve.

Fan Flow
(b)
1. Record the auxiliary temperature at the configured maximum airflow.
2. Close the primary air valve.
3. Turn on the fan (if present).
4. Monitor auxiliary temperature for 3 minutes or until it changes by 10°F.
5. Record the auxiliary temperature.

(b)
1. If no fan is present, open the air valve to the configured minimum local heating airflow.
2. If the fan is present, close the air valve and turn on the fan.
3. Record the auxiliary temperature.
4. Open the water valve to 100% open.
5. Monitor the auxiliary temperature for 10 minutes or until it changes by 10°F.

(b)
1. If no fan is present, open the air valve to the configured minimum local heating airflow.
2. If the fan is present, close the air valve and turn on the fan.
3. Record the auxiliary temperature.
4. Progressively turn on each local stage 30 seconds after the previous stage until all stages are
energized.
5. Record the auxiliary temperature 30 seconds after each stage is energized.

(a) If there is no flow sensor, the controller runs in pressure dependent mode and record 40% and 100% during this auto-commissioning step.
(b) Requires a functional auxiliary sensor in the discharge air stream. The auxiliary sensor must be configured for discharge air temperature.
