Condition / Response
The unit has been operating in "Pre Cool" for 120
minutes.
This is an occupied mode that stops ventilation.
If Pre Cool command is removed after the diagnostic
has been activated it will be cleared.
The relief air damper position has been lower than
the damper command by 10% for 5 continuous
minutes.
The relief fan remains on but its speed is limited to
the value of the relief damper voltage input.
The relief air damper position has been greater than
the damper command by 10% for 5 continuous
minutes.
The relief fan remains on but its speed follows the
lower commanded value, or if the command
increases the speed is limited to no greater than the
value of the relief damper voltage input.
The Relief Air Damper Input has failed out of range.
This voltage is an indication of actual damper
position.
Relief damper is closed and the relief fan is
commanded off. Economizer cooling is terminated.
Relief Fan X is expected to be running, this diagnostic
will be generated when a No Flow condition exists for
40 continuous seconds.
Failure of fan X with other relief fans available:
Generate "Relief Fan X Proving Failure" diagnostic
and take no other action.
Failure of fan X with other relief fans not-available:
The relief damper will be closed, the relief fan will be
commanded off, economizing will be disabled and the
outside air damper will be driven to the active
minimum position.
If the Return air temperature exceeds 135F then an
Immediate Stop will be generated. This is intended to
shut the unit down the unit if high duct temperatures
exist.
This Diagnostic is only available if the Return Air
Temperature is operating normally.
The Return Air Humidity sensor has failed out of
range.
This drives a 'fall back' response to Economizer
enthalpy decision.
The Return Air Temperature sensor has failed out of
range.
Rapid Restart. Affects DX capacity operation and
target capacity, see spec for details.
Rapid Restart. Economizer capacity terminates on
rapid start time (rather than return air temperature),
see spec for details.
This drives a 'fall back' response to Economizer
enthalpy decision.
