control module. When the unit faults, the LED will flash a
certain number of times. A flashing green LED diagnostic code
indicates that a sequence of events has forced a lockout
condition and is in a lockout state. Number of flashes indicates
the type of failure. The flash code or number of flashes will
occur followed by a pause before it repeats. Any power
interruption of more than 2 seconds – with the reapplication of
power, will re-set the controls. If a fault condition existed prior
to the reset, the fault condition will clear with the exception of
the FV sensor codes. If the fault condition still exists after the
application of power, the control will indicate the appropriate
fault.
