Airflow is a status only item that indicates whether or not
discharge airflow is detected. Airflow status is sensed by a
binary input delivered to the controller by a differential pressure
switch (PC7) . On VAV units duct static pressure is also a factor
in the indication of airflow.
Supply Fan is a status only item which indicates whether or
not the controller is commanding the unit supply fan on .
Ret/Exh Fan is a status only item which indicates whether or
not the controller is commanding the unit RF/EF fan on .

RF/EF Speed a status only item that indicates the current
return/exhaust fan speed .
Speed Cmd is a status only item that indicates the current
return/exhaust fan commanded speed .
Bldg Press is a status only item which indicates the building
static pressure at the building static pressure sensor location .
BldgSP Spt is an adjustable item which sets the building static
pressure set point used for controlling the speed of the exhaust
air fan . The variable speed exhaust air fan is modulated to
maintain the building pressure at this value .

SAF Speed is a status only item that indicates the current
supply fan speed .
Speed Cmd is a status only item that indicates the current
supply fan commanded speed .
Duct Press is a status only item which indicates the current
pressure of the supply air ductwork . The duct pressure is
measured at the location in which the duct static pressure tap
was field installed. This device is not factory installed.
DuctSP SPT is an adjustable item which sets the duct static
pressure set point used for controlling the speed of the supply
air fan . The variable speed supply air fan is modulated to
maintain the duct pressure at this value .
IAQ PPM is a status only item which indicates the current
reading from the CO2 sensor .
OA Flow is a status only item which indicates the current
outdoor airflow based on an optional OA airflow sensor input
used when the unit is equipped with a field supplied OA
measuring station .
Min OAFlw Spt is an adjustable item that is used to set the
minimum CFM when the unit is equipped with a field supplied
OA measuring station .
Bldg Press is a status only item which displays the current
building static pressure reading .
BldgSP Spt is a status only item which indicates the building
static pressure set point used for controlling the exhaust fan
speed . The exhaust fan speed is modulated to maintain the
building static pressure sensor input to this value . Once a valid
password has been entered this item becomes an adjustable
item .
