BSP Input is an adjustable item used to select whether on
not a building static pressure sensor is connected to the unit
controller . If this is set to No the controller ignores any building
static pressure input . If BSP control of the supply fan is desired
this parameter must be set to Yes . This parameter applies only
to 100% OA unit configurations.
Remote SF Cap is an adjustable item for setting the supply fan
speed by the keypad or by a network control signal .
DSP DB is an adjustable item which sets a dead band around
the DuctSP Spt= parameter . No duct static pressure control
action is taken when the current duct static pressure input is
within this dead band .
SAF Ramp Time is an adjustable item that sets the amount
of time it will take for the variable speed fan to drive from
its minimum to maximum speed as well as its maximum to
minimum speed . The SAF Ramp Time= value on the keypad
must be changed whenever the ramp time of the variable
speed fan is changed . The ramp up time must equal the ramp
down time, and both must equal the SAF RampTime value to
provide stable operation .
Min Period is an adjustable item that sets the duration of the
sample time between speed changes . The sample time must
be long enough to allow the static pressure to get very close to
its steady state value before another calculation is made .
Max Spd Chg is an adjustable item that sets the maximum
value for a speed increase or decrease . This speed change
(either a positive or negative value) is added to the current
fan speed whenever the duct static pressure is outside of the
deadband, and the Min Period time has passed since the
previous speed change .
DuctPress1 is a status only item that indicates the current
value for the duct status pressure sensor .
Min Clg Spd is an adjustable item that sets the minimum
supply fan speed used for cooling operation when 1ZnVAV is
selected as the method of supply fan control .
Max Clg Spd is an adjustable item that sets the maximum
supply fan speed used for cooling operation when 1ZnVAV is
selected as the method of supply fan control .

Min Htg Spd is an adjustable item that sets the minimum
supply fan speed used for heating operation when 1ZnVAV is
selected as the method of supply fan control .
Max Htg Spd is an adjustable item that sets the maximum
supply fan speed used for heating operation when 1ZnVAV is
selected as the method of supply fan control .
Space Period is an adjustable item that sets the "sampling
time" used in the PI control function to vary the supply fan
speed when 1ZnVAV 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
1ZnVAV supply fan control is selected .
Space PAT is an adjustable item that sets the "project ahead
time" used in the PI control function to vary the supply fan
speed when 1ZnVAV 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 1ZnVAV supply fan control is selected .
Min PPM is an adjustable item that sets the minimum PPM
value of the field supplied CO
Max PPM is an adjustable item that sets the maximum PPM
value of the field supplied CO
V/mA @ Min PPM is an adjustable item that sets the DC
voltage or mA value at the minimum PPM value of the field
supplied CO input signal .
2
V/mA @ Max PPM is an adjustable item that sets the DC
voltage or mA value at the maximum PPM value of the field
supplied CO input signal .
2
Min SAF PPM is an adjustable item that sets the PPM value at
which the supply fan speed is controlled to minimum when CO
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 supply fan control is selected .
2
Min PPM Spd is an adjustable item that sets the supply fan
speed when the CO 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 input signal is at maximum when CO
2
supply fan control is selected .
