Min PPM is an adjustable item that sets the minimum PPM
value of the eld supplied CO
2
input signal.
Max PPM is an adjustable item that sets the maximum PPM
value of the eld supplied CO
2
input signal.
V/mA @ Min PPM is an adjustable item that sets the DC
voltage or mA value at the minimum PPM value of the eld
supplied CO
2
input signal.
V/mA @ Max PPM is an adjustable item that sets the DC
voltage or mA value at the maximum PPM value of the eld
supplied CO
2
input signal.
Min SAF PPM is an adjustable item that sets the PPM value
at which the supply fan speed is controlled to minimum when
CO
2
supply fan control is selected.
Max SAF PPM is an adjustable item that sets the PPM value
at which the supply fan speed is controlled to maximum when
CO
2
supply fan control is selected.

speed when the CO
2
input signal is at minimum when CO
2
supply fan control is selected.
Max PPM Spd is an adjustable item that sets the supply fan
speed when the CO
2
input signal is at maximum when CO
2
supply fan control is selected.
Min CFM is an adjustable item that sets the minimum CFM
value of the eld supplied airow station input signal.
Max CFM is an adjustable item that sets the maximum CFM
value of the eld supplied airow station input signal.
V/mA @ Min CFM is an adjustable item that sets the DC
voltage or mA value at the minimum CFM value of the eld
supplied airow station input signal.
V/mA @ Max CFM is an adjustable item that sets the DC
voltage or mA value at the maximum CFM value of the eld
supplied airow station input signal.
SAF CFM DB is an adjustable item that sets the “deadband”
used in the PI control function to vary the supply fan speed
when airow (CFM) supply fan control is selected.
SAF CFM Period is an adjustable item that sets the “sample
time” used in the PI control function to vary the supply fan
speed when airow (CFM) supply fan control is selected.
Space Gain is an adjustable item that sets the “gain” used
in the PI control function to vary the supply fan speed when
airow (CFM) supply fan control is selected.
Space Max Chg is an adjustable item that sets the maximum
value of increase or decrease of the supply fan speed each
period used in the PI control function to vary the supply fan
speed when airow (CFM) supply fan control is selected.
BSP DB is an adjustable item that sets the “deadband” used
in the PI control function to vary the supply fan speed when
building static pressure (BSP) supply fan control is selected.
BSP Period is an adjustable item that sets the “sample time”
used in the PI control function to vary the supply fan speed
when building static pressure (BSP) supply fan control is
selected.
BSP Gain is an adjustable item that sets the “gain” used in the
PI control function to vary the supply fan speed when building
static pressure (BSP) supply fan control is selected.
Max Spd Chg is an adjustable item that sets the maximum
value of increase or decrease of the supply fan speed each
period used in the PI control function to vary the supply fan
speed when building static pressure (BSP) supply fan control is
selected.
DSP Ctrl Dly is an adjustable item that sets the duration of
time that the minimum speed signal is sent to the variable
speed supply air fan after the supply fan is started via a digital
output. Control reverts to either duct pressure or speed after
the fan has been on for the DSPCtrlDelay (default 30 seconds).
Min Speed is an adjustable item which is used to set the
minimum supply fan speed (default 33%).
VAVBox Out is a status only item that indicates the current
value of the VAV output. The VAV output is only available to the
eld via network communications.
Max Vent Speed is an adjustable item that sets the supply fan
speed when an external ventilation override input to the supply
fan is present.
Max SAF RPM is an adjustable item that sets the maximum
RPM value for the supply air fan. Note this is set based on the
supply fan model size and the system specications.
ECM Status is a status only item that indicates the current
status of the supply fan motor.
