nciFanSettings (nviFP39)
This configuration property defines the different available fan configurations.
Field Description
FanCtrlType
This configuration is used to choise the fan control type (Variable, 3Speed, 2Speed,1 Speed or
None)
FanMode
This configuration is used to configure the behavior of the fan.
Continuous = Fan continuously operating
Cycle = Fan cycling based on cooling/heating load
Con Cycle = Fan continuously operating in occupied mode and cycling in unoccupied mode.
Cycle Heat = Fan cycling based on heating load only
Cycle Cool = Fan cycling based on cooling load only
CoolMaxFanSpeed This configuration is used to set the maximum fan speed in cooling mode.
HeatMaxFanSpeed This configuration is used to set the maximum fan speed in heating mode.
FanOffDelay
This configuration is used to set the Fan Off delay. On a request to stop the fan, the fan will
run at minimum speed during this delay before being completely stopped. During that time,
heating/cooling operation is disabled.
FanSpeed1Level
This configuration is used to configure the load (heating/cooling) required to start the fan when
in Cycle mode configuration. This is also the fan speed at which the fan will be set when the
system is overridden to low speed and nviFanSpeedCmdDigital (nciCb01_124/ConstantBool3)
is set to TRUE.
FanSpeed2Level
This configuration is used to configure the fan speed at which the fan will be set when the
system is overridden to medium speed and nviFanSpeedCmdDigital (nciCb01_124/
ConstantBool3) is set to TRUE.
FanSpeed3Level
This configuration is used to configure the fan speed at which the fan will be set when the
system is overridden to high speed and nviFanSpeedCmdDigital (nciCb01_124/
ConstantBool3) is set to TRUE.
VarSpeedMinLevel This configuration is used to set the minimum fan speed operation.
FanCoolLow
This configuration is used to set the minimum cooling load required to start the fan operation
algorithm
FanCoolHigh
This configuration is used to set the cooling load at which the fan will be set to
CoolMaxFanSpeed.
FanHeatLow
This configuration is used to set the minimum heating load required to start the fan operation
algorithm
FanHeatHigh
This configuration is used to set the heating load at which the fan will be set to
HeatMaxFanSpeed.
