Troubleshooting
•
If sensor and receiver still do not operate properly, replace bad components. If unit passes
tests, check VV550 operation.
4. Defective VAV VV550
•
Disconnect the receiver sensor wires on the VAV VV550 on terminals TB3-1 and TB3-2 and
measure the VDC. It should be 5VDC. If 5VDC is not present check incoming power to the VAV
VV550 Controller board on TB1-1 and TB1-2. Should measure 24VAC ± 10%. If you measure
the proper voltage at TB1-1 and TB1-2 and no voltage at TB3-1and TB3-2 replace VV550.
Note:
If no voltage at TB1-1 and TB1-2, see VV550 failure procedures
•
Disconnect the receiver sepoint wires on the VAV VV550 on terminals TB3-2 and TB3-3 and
measure the VDC. It should be 5VDC. If 5VDC is not present check incoming power to the VAV
VV550 Controller board on TB1-1 and TB1-2. Should measure 24VAC ± 10%. If you measure
the proper voltage at TB1-1 and TB1-2 and no voltage at TB3-2and TB3-3 replace VV550.
