SERVICE CONFIGURATION
Compressor Stages
The number of mechanical cooling stages. This decision is not
configurable.
Default = Three stages
Economizer Exists
Set to Yes at factory. This decision is not configurable.
Default = Yes
VFD Input
Defines the electrical control signal used by the Variable Fre-
quency Drive's (VFD) input.
Range = 0-10 Vdc, 2-10 Vdc
Default = 2-10 Vdc
Max VFD Output
The maximum output signal the control supplies to the VFD as a
percentage of its range. The balancer can set this to adjust the
unit's maximum airflow.
Range = 15% to 100%
Default = 100%
Min VFD Output
The minimum output signal the control supplies to the VFD as a
percentage of its range. This must be set to ensure the unit's mini-
mum airflow.
Range = 15% to 100%
Default = 25%
Heat Type
The type of heating used by the unit.
Range = Electric/Gas
Default = Gas
Number of Heat Stages
The number heat stages.
Range = 1 / 2 / 0 (no heating)
Default = 2
SA Tempering
Supply Air Tempering permits using heating, if installed to temper
OA while unit is in Fan Only or IAQ Override mode.
Range = Disable/Enable
Default = Disable
Continuous Occupied Exhaust
This point tells the controller when to run the power exhaust if
equipped on the unit.
If set to YES, the power exhaust will be on all the time when in
occupied mode and will be off when in unoccupied mode. If set to
NO the power exhaust will be controlled by the Power Exhaust
Setpoint.
Range = YES/NO
Default = NO
DCV Control
Enables demand controlled ventilation (DCV) if valid CO
value is available and the unit has an economizer installed.
Range = Disable/Enable
Default = Disable
Indoor CO
Sensor Value @min (ma)
2
The CO
value that corresponds to a 4mA input at the appropriate
2
input channel.
Range = 0 to 9999 ppm
Default = 0 ppm
Indoor CO
Sensor Value @max (ma)
2
The CO
value that corresponds to a 20mA input at the appropri-
2
ate input channel.
Range = 0 to 9999 ppm
Default = 2000 ppm
Outdoor CO
2
The CO
value that corresponds to a 4mA input at the appropriate
2
input channel.
Range = 0 to 9999 ppm
Default = 0 ppm
Outdoor CO
2
The CO
value that corresponds to a 20mA input at the appropri-
2
ate input channel.
Range = 0 to 9999 ppm
Default = 2000 ppm
NOTE: The indoor and outdoor min and max mA setting are used
to set the linear curve of mA vs. PPM.
System Space Temperature
The network space temperature value that the controller is using
for control (if applicable).
Range = N/A
Default = -999.0°F
System Space RH
The network relative humidity value that the controller is using for
control (if applicable)
Range = N/A
Default = -999.0%
System Space AQ
The network indoor air quality (CO
using for control (if applicable)
Range = N/A
Default = -999.0 PPM
System Cool Demand Level
The system cool demand level being received over the network
Range = N/A
Default = 0-3
System Heat Demand Level
The system heat demand level being received over the network
Range = N/A
Default = 0-3
System Outdoor Air Temperature
Allows the outdoor air temperature value to be network readable
when enabled.
Range = N/A
Default = -999.0°F
System Outdoor AQ
Allows network readable value of OAQ for calculation during dif-
ferential OAQ CO
sensor
control
2
Range = N/A
Default = -999.0 PPM
System Fire / Smoke
Allows network readable fire/smoke signal to invoke shutdown
action in the RTU
Range = N/A
Default = OFF
