POWER Green UCB power indicator Lit indicates 24 VAC is present at 24V~ IN COM and HOT pins
FAULT
FAULT
Red networking error and firmware error
indicator
1/10th second on/off flashing indicates a networking error
(polarity, addressing, etc.) or a firmware error (likely correctable
with re-loading from USB flash drive)
SA BUS
SA BUS
Green UCB SA bus communication
transmission indicator
Lit/flickering indicates UCB-to-economizer board SA bus
communication is currently active, off indicates the economizer
board is awaiting SA bus communication
