Disch Air
is a status only item which displays the current temperature reading from the unit's
discharge air temperature sensor (DAT). This sensor is standard on all units.
DAT Clg Spt
is a status only item which indicates the temperature that the DAT should be
maintained at when it is in the cooling mode of operation.
DAT Htg Spt
is a status only item which indicates the temperature that the DAT should be
maintained at when in the heating mode of operation.
Min DAT Limit
is a status only item which indicates the discharge air low limit temperature
on CAV zone control units. Heating will be activated to maintain this setting when the
discharge temperature falls below it during the Fan Only operating state. On VAV or CAV
discharge control units, the minimum discharge temperature limit is the DAT Clg Spt.
SAFSpeed
is a status only item which indicates the capacity of the supply air fan.
DSP
is a status only item which displays the current duct static pressure reading.
DuctSP Spt=
is a status only item which indicates the duct static pressure set point used for
controlling the VFD for the supply air fan. The VFD is modulated to maintain the duct
pressure at this value.
RF/EF Speed
is a status only item indicating the capacity of the return fan/exhaust air fans.
BSP
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 return/exhaust fan VFD. The return/exhaust fan VFD is modulated to maintain
the building static pressure sensor input to this value.
OA Temp
is a status only item which displays the current temperature reading from the unit
mounted outdoor air temperature sensor. This sensor is standard on all units.
EW Temp
is a status only item that displays the current temperature reading from the unit
mounted entering water temperature sensor. The sensor is standard on all water-cooled units.
Rel Humidity
is a status only item that displays the current relative humidity reading from the
optional humidity sensor.
