Description
Network Configuration Property Inputs (NCIs)
Occupancy
Temperature
Setpoints
nciSetpoints
(3)
SCPTsetPnts
50 to 95ºF
10 to 35ºC
Defaults:
See Description*
No
Defines the space temperature heating and cooling setpoints
for different occupancy modes. See
The Occupancy Temperature Setpoints must be kept in
ascending order as follows:
unoccupied_heat <= standby_heat
<= occupied_heat <= occupied_cool
<= standby_cool <= unoccupied_cool
Additional interaction rules
• occupied_cool > (occupie nciOccDiff)
• standby_cool > (standb nciOccDiff)
• unoccupied_cool>(unoccupinciUnoccDiff)
• occupied_heat < (occupied_cool – nciOccDiff)
• standby_heat < (standby_cool – nciOccDiff)
• unoccupied_heat<(unoccupied_cool–nciUnoccDiff)
*Default Values
• Occupied_cool = 75ºF, 23.88ºC
• Standby_cool = 77ºF, 25.00ºC
• Unoccupied_cool = 85ºF, 29.44ºC
• Occupied_heat = 70ºF, 21.11ºC
• Standby_heat = 66ºF, 18.88ºC
• Unoccupied_heat = 60ºF, 15.55ºC
Receive Heartbeat
nciRcvHrtBt
SCPTmaxRcvTime
0 to 6553.4 sec
Default: 0 sec
(Disabled)
No
Specifies the maximum amount of time the supported
overrides must be refreshed (i.e. written) before the unit
reverts back to the default value. Each variable supported by
Receive Heartbeat has a separate timer associated with it.
The value of 0 disables this feature.
Supported Variables
• nviApplicMode
• nviAuxHeatEnable
• nviComprEnable
• nviEnergyHoldOff
• nviFanOnAuto
• nviHumidistat
• nviOccSchedule
• nviOccSensor
• nviSetptOffset
• nviSpaceTemp
Room Sensor
Setpoint Adjust
Enable/Disable
nciLocSptEnable
(7)
UCPTlocSptEnable
0 to 1
Default: Enabled
No
Enables or disables the local hardwired setpoint adjustment.
If the value of nciLocSptEnable is set to 0, this disables
setpoint control from a room sensor and enables setpoint
control from the network.
Supported Values
0 = Disabled
1 = Enabled
Second Stage
Setpoint Differential
nciStg2SptDiff
UCPTstg2SptDiff
1 to 5°F
0.55 to 2.78°C
Default:
2ºF / 1.11ºC
No
Used to determine the Second Stage Heating and Cooling
ON setpoints from the First Stage ON setpoints for units
controlled by room sensors.
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

The software major version of the communication module
firmware.
Do not modify this configuration property.
