Condition / Response
The supply air static pressure exceeded the Duct
Static Pressure High Limit Setpoint for at least one
second continuously.
The unit will shut down but will be allowed to restart
once the pressure falls below the high limit setpoint.
Note: VOM/EOM Behavior - During these modes this
diagnostic changes behavior to a warning
diagnostic and the active mode will be honored. If
the mode has the supply fan On its speed will be
reduced to minimum.
The supply air pressure has exceeded the Duct Static
Pressure High Limit Setpoint for the 3rd consecutive
time without the supply fan running for 3 continuous
minutes. (If the fan runs for 3 continuous minutes the
counter will be reset.)
The unit will shut down but will not be allowed to
restart even if the pressure falls below the high limit
setpoint.
Note: VOM/EOM Behavior - During these modes this
diagnostic changes behavior to a warning
diagnostic and the active mode will be honored. If
the mode has the supply fan On its speed will be
reduced to minimum.
The Supply Air Temperature sensor has failed.
If no other source for Discharge Air Temperature all
heating, cooling, and economizer capacity control is
terminated.
The discharge pressure sensor for circuit X has failed
out of range.
Circuit X operation will be inhibited.
There is no valid source for Discharge Pressure
Sensor Active. All sources are unavailable.
VVDA units only.
See 'Duct Static Pressure Local is Invalid' below for
VVDA units.
There is no valid source for Discharge Pressure
Sensor Local. Both the local wireless and wired
sensors are unavailable.
For all units.
For VVDA units:
• The supply fan speed is overridden to minimum
speed.
• DX Cooling is allowed
• All heating is disabled
For CVDA, CVZT and VVZT units:
• The supply fan operation is normal
• High Duct Static Limit Protection, High Duct Static
Limit Trip, and Full Airflow Limit Control is disabled.
The unit is following Emergency Override Pressurize.
The unit is following Emergency Override
Depressurize.
The unit is following Emergency Override Purge.
