Description
Network Conguration Property Inputs (NCIs)
Send Heartbeat nciSndHrtBt SCPTmaxSendTime
0 to 6553.4 sec
Default: 0
(Disabled)
No
Denes the maximum period of time that elapses before
the network variable outputs (NVOs) shown below are
automatically updated. Each NVO supported has a separate
timer associated with it. The BAS may be able to detect a
missing heartbeat from the unit controller to determine that
communication is lost and take corrective action. The value
of 0 disables the auto update feature.
Supported Variables
• nvoDischAirTemp
• nvoEffectOccup
• nvoEffectSetpt
• nvoFanSpeed
• nvoLocalSpaceTmp
• nvoSetpoint
• nvoSetptShift
• nvoSpaceTemp
• nvoUnitStatus
Device Software

(Major Version)
nciDevMajVer SCPTdevMajVer 0 to 255 No
The software major version of the communication module
rmware.
Do not modify this conguration property.
Device Software

(Minor Version)
nciDevMinVer SCPTdevMinVer 0 to 255 No
The software minor version of the communication module
rmware.
Do not modify this conguration property.
Software Jumpers nciSoftJumpers UCPTsoftJumpers 16 Characters No
Sets the software jumper conguration. This property is not
implemented in unit controller software.

nciUnoccDiff UCPTunOccDiff
2 to 10ºF
1.11 to 5.56ºC
Default:
2ºF / 1.11ºC
No
Sets the Unoccupied hysteresis that determines the Effective
OFF setpoints.
Interaction Rule
nciUnoccDiff < (unoccupied_cool – unoccupied_heat)
1. Analog Null (0x7FFF) is a discrete temperature value of 621.806ºF/327.67ºC. Its purpose is to indicate a sensor failure condition or when the unit controller is not
using that temperature value.
2. The Network Variable (NV) index number is a unique identier for certain LonWorks variables. Some BAS companies use this numeric value instead of text to
reference these variables. The NV index number can also be found in the XIF le.
3. After Receive Heartbeat is enabled, this variable reverts to the default (non-override) value if it is not refreshed often enough through a network command or if
communication is disabled (i.e. the device is disabled or is ofine).
