Network Conguration Property Inputs (NCIs)

(3)
SCPTsetPnts
50 to 95ºF
10 to 35ºC
Defaults:
See Description*
No
Denes the space temperature heating and cooling setpoints
for different occupancy modes. See Effective Occupancy
Modes.
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 > (occupied_heat + nciOccDiff)
• standby_cool > (standby_heat + nciOccDiff)
• unoccupied_cool>(unoccupied_heat+nciUnoccDiff)
• 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
Species 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

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

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
Denes 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
