primary system pump is operating. If output (SO) is set to
System Backup Pump, system pump output (SO) is
energized and System pump Feedback is de-energized the
System Backup Pump output (SO) is energized.
When the Fuel Valve Energized input (CS) is not energized
and Input (SI) is energized the modulation rate is set to the
"Low Fire Spd" setpoint. When input (SI) is not energized
the modulation rate is set to "Fan Purge Spd" setpoint.
When the fuel valve energized input (CS) is energized input
(SI) is ignored.
Never close output (SO).

System Pump Feedback indicates the Primary System
Pump is not operating.
Closes when a any alarm is active.
