Description
Network Configuration Property Inputs (NCIs)
Send Heartbeat
nciSndHrtBt
SCPTmaxSendTime
0 to 6553.4 sec
Default: 0
(Disabled)
No
Defines 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

No
Sets the Unoccupied hysteresis that determines the Effective

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 identifier for certain
L
on
W
orks
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 file.
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 offline).
