4. On the Read/Write screen, in the Operation box select
the Monitor radio button by clicking on it. In the Display
box select the Decimal radio button by clicking on it.
5. Enter the following string of memory addresses into the
Memory Address box exactly as shown then press the
Enter key: 0212-0217,0A01-0A02,0204,0505-0507,
0901-0902,091A-091B,0935-0936.
6. Notice in the Read/Write area that the values located in
0A01 and 0A02 are identical. Write to 0A01 by clicking
on the value and change it to any value other than the
value at 0A02.
7. Write a value of 4 to location 0204. This will reset the
controller. The program will stop; all outputs will go off.
8. Write 255 to location 0212, this will return a value of 1.
This will begin forcing the F&BP damper to the full
bypass position (or begin closing the valve)
9. Watch memory location 0506 change, when this value
stops changing, the damper is in the full bypass position
(or valve fully closed). On a sheet of paper, write this value
down for later use.
10. Write a 0 to location 0212. Then write a 255 to location 0213,
this will return a value of 1. This will begin forcing the F&BP
damper to the full face position (or begin opening the valve).
11. Watch memory location 0506 change, when this value
stops changing, the damper is in the full face position (or
valve fully opened). On a sheet of paper, write this value
down for later use.
12. Write a 0 to location 0213.
13. Using the Read/Write screen write the lowest value of the
two numbers you wrote down on the sheet of paper to
location 091A, then write the higher value to location 091B.
14. Change location 0A0l 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 control-
lers except you must replace all instances of 0A01 with
8001, and replace all instances of 0A02 with 8002.
MicroTech 325 Water Valve Calibration
The following procedure is for Model 13-hot water valve only
(not cold water valve)
1. Establish communications to the controller using a PC
with the Windows Monitor software and proper cables.
2. In the Windows Monitor program, go to Support menu
and choose Read/Write.
3. Make sure the address located in the Controller Address
box is the same as the UV you wish to work on. If you are
directly connected to the controller you wish to work on,
and the controller is not a Master in a Master/Slave
network, then the Controller Address 00.FF may be used.
4. On the Read/Write screen, in the Operation box select
the Monitor radio button by clicking on it. In the Display
box select the Decimal radio button by clicking on it.
5. Enter the following string of memory addresses into the
Memory Address box exactly as shown then press the
Enter key: 0212-0217,0A01-0A02,0204,0505-0507,
0901-0902,091A-091B,0935-0936
6. Notice in the Read/Write area that the values located in
0A01 and 0A02 are identical. Write to 0A01 by clicking on
the value and change it to any value other than the value
at 0A02.
7. Write a value of 4 to location 0204. This will reset the
controller. The program will stop; all outputs will go off.
8. Write 255 to location 0216, this will return a value of 1.
This will begin forcing the valve closed.
9. Watch memory location 0505 change, when this value
stops changing, the valve is fully closed. On a sheet of
paper, write this value down for later use.
10. Write a 0 to location 0216. Then write a 255 to location
0217, this will return a value of 1. This will begin forcing
the valve opened.
11. Watch memory location 0505 change, when this value
stops changing, the valve is fully opened. On a sheet of
paper, write this value down for later use.
12. Write a 0 to location 0217.
13. Using the Read/Write screen write the lowest value of
the two numbers you wrote down on the sheet of paper to
location 0935, then write the higher value to location 0936.
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 control-
lers except you must replace all instances of 0A01 with
8001, and replace all instances of 0A02 with 8002.
