9. Watch memory location 0507 change, when this value stops
changing, the OA damper should be fully opened. On a
sheet of paper, write this value down for later use.
10. Write a 0 to location 0214. Then write a 255 to location
0215, this will return a value of 1. This will begin closing the
OA damper.
11. Watch memory location 0507 change, when this value stops
changing, the OA damper is fully closed. On a sheet of pa-
per, write this value down for later use.
12. Write a 0 to location 0215.
13. Using the Read/Write screen write the lowest value of the
two numbers you wrote down on the sheet of paper to
location 0901, then write the higher value to location 0902.
14. Change location 0A01 to match 0A02.
15. Reset the controller by writing 4 to location 0204.
16. The controller should start its program and begin
operating normally.
Note: The same procedure is used for MicroTech 125
controllers except you replace all instances of 0A01 with
8001, and replace all instances of 0A02 with 8002.
