VAV Start Up/Check Out Procedure
Applying Power to the Receiver
Restore power to the VAV VV550 Controller. Observe LED5 on the receiver ( Figure 14, p. 33 ). It will
light and stay constantly On when 24 V power is normal.
Receiver Indicates Readiness to Associate
After initial power up, the receiver conducts a channel scan for 10 seconds. During this time, the
receiver selects from 16 available channels the clearest channel on which to operate. LED1, LED2,
and LED3 flash rapidly in succession (round-robin style) while the channel scan is in progress.
Note: Do not attempt association until the channel scan is finished. After the channel scan is
finished, LED3 will begin blinking (one-blink pattern) to show that the receiver is ready to
be associated with a sensor. LED3 will stop blinking when association has been established
(
Figure 15, p. 33 ).
