Table 1 provides an automatic tuning checklist.

Check zones to make sure:
|
|
Validate the sequence of operations for every typical system to ensure compliance with specs. |
|
Transfer to all controllers using the NAE Point Schedule and Parameters sheets. |
|
Ensure the NAE Point database has enough trending defined to be able to review operation. For example, in the case of a VAV box, make sure that a trend has been defined for the zone temperature, setpoint, and heating source. |
|
Perform a box flow test for all VAV Controller zones using a CCT Box Flow Test. |
|
Using the NAE Point Schedule parameter sheets, write zone reheat valves to 100%, then 0%, using Flush Position and System Mode Water Flush. Then, read the discharge air temperature to find valves not fully stroking. |
|
Calibrate inputs and outputs as required by specifications. |
|
Ensure all points are reliable and are mapped correctly to the NAE and Graphics. |
|
Run zone reports using Tailored Summaries to identify zone problems. |
|
Run trend reports using the Export Utility or Trend Viewer to make sure each typical system is tuned properly with no hunting. |
|
Test application loops and tuning loops for reaction to system failures. |
|
After tuning is complete, restart the system to verify system performance at startup. |
