OPTIONAL VAV CONTROL BOARD FLASH CODES

Flash codes are also utilized by the VAV add-on board
to aid in troubleshooting optional VAV applications.
Flash codes are displayed by a red LED located near
the center of the board using a short on/off cycle
(approximately 200-ms on and 200-ms off).
To verify that the board is functioning correctly, the
LED will display a repetitive 1 second on, 1 second off
"heartbeat". Do not confuse this "heartbeat" with the
error flash codes shown in the table below. To prevent
confusion, a 1-flash, flash code is not used.
