Apply Changes - the Apply Changes ag must be changed
from no to yes in order for the controller to recognize
the changes. Setting the Apply Changes ag to YES will
automatically reset the controller.
Min OA Reset is an adjustable item that sets the type of
minimum OA damper position reset to be used. When this
is set to “None” the Min OA Pos= parameter is set to the
Ventilation Limit. When this is set to “Network,” “Ext VDC,” “Ext
mA,” “IAQ VDC,” or “IAQ mA” then the Min OA Pos= parameter
varies from the Ventilation Limit down to the Demand Control
Ventilation Limit as the reset signal goes from its maximum to
minimum value.
NOTE: When the Min OA Reset type is set to Network and
the Apply changes ag is set to yes, the value of the
Vent Limit is automatically set to 100%, the value of
the DCV limit is set to 0% and the LoFlo V Lmt is set
to 0%.
BSP OA Ovrd is an adjustable item used to enable/disable the
building static pressure override feature.
Rst Lmt Snsr is an adjustable item used to set the sensor to
be used in conjunction with the OA reset limit function.
OA @ MinV/mA is an adjustable item used when Min OA
Reset= is set to “Ext VDC” or “Ext mA” to dene the Min OA
Pos= is when the eld signal is at minimum value.
NOTE: Min OA Pos= is limited above the Demand Control
Ventilation Limit.
OA @ MaxV/mA is an adjustable item used when Min OA
Reset= is set to “Ext VDC” or “Ext mA” to dene the Min OA
Pos= when the eld signal is at the minimum value.
NOTE: Min OA Pos= is limited below the ventilation limit.
Min V/mA is an adjustable item used to set the minimum value
of the eld input signal.
Max V/mA is an adjustable item used to set the maximum
value of the eld input signal.
PPM @ DCV Limit is an adjustable item used when Min OA
Reset= is set to “IAQ VDC” or “IAQ mA” to dene at what
PPM value the Min OA Pos= is to be at the Demand Control
Ventilation Limit value.
PPM @ Vent Limit is an adjustable item used when Min OA
Reset= is set to “IAQ VDC” or “IAQ mA” to dene at what PPM
value the Min OA Pos= is to be at the Ventilation Limit value.
IAQ PPM is a status only item which indicates the current
reading from the CO
2
sensor.
Min PPM is an adjustable item that sets the minimum PPM
value.
Max PPM is an adjustable item that sets the maximum PPM
value.
V/mA @ Min PPM is an adjustable item that sets the
minimum PPM value at the minimum DC voltage or mA value
of the CO
2
sensor used when Min OA Reset= is set to “IAQ
VDC” or “IAQ mA.”
V/mA @ Max PPM is an adjustable item that sets the
maximum PPM value at the maximum DC voltage or mA value
of the CO
2
sensor used when Min OA Reset= is set to “IAQ
VDC” or “IAQ mA.”
Min CFM is an adjustable item that sets the minimum CFM
value of the eld supplied ow station.
Max CFM is an adjustable item that sets the maximum CFM
value of the eld supplied ow station.
V/A @ Min CFM is an adjustable item that sets the sensor
input value at minimum CFM reading.
V/A @ Max CFM is an adjustable item that sets the sensor
input value at maximum CFM reading.
Min Fan Diff is an adjustable item which sets a differential
between the discharge and return fan capacities above which
the minimum allowable Min OA Pos= begins to be reset
upwards from the Demand Control Ventilation Limit toward the
Ventilation Limit.
Max Fan Diff is an adjustable item which sets a differential
between the discharge and return fan capacities at which
the minimum allowable Min OA Pos= is fully reset up to the
Ventilation Limit.
Min Clg Spd is an adjustable item that sets the discharge fan
speed on a VAV unit at which the Ventilation Limit reaches the
LoFloVent= value.
Des Clg Spd is an adjustable item used to adjust the design
cooling speed setpoint.
Design Flow is an adjustable item used to turn the optional
DesignFlow outdoor airow measuring reset function on and
off. This is one of several available methods of automatically
resetting the Min OA Pos parameter.
Field OA Stn is an adjustable item used to turn the optional
eld supplied outdoor airow measuring station function ON
and OFF.
