Network Conguration Property Inputs (NCIs)
Occupancy
Temperature
Setpoints
nciSetpoints 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)
occupied_cool <= nciClgSptHiLim
occupied_cool >= nciClgSptLoLim
standby_cool > (standby_heat + nciOccDiff)
standby_cool <= nciClgSptHiLim
standby_cool >= nciClgSptLoLim
unoccupied_cool>(unoccupied_heat+nciUnoccDiff)
unoccupied_cool <= nciClgSptHiLim
unoccupied_cool >= nciClgSptLoLim
occupied_heat < (occupied_cool – nciOccDiff)
occupied_heat <= nciHtgSptHiLim
occupied_heat >= nciHtgSptLoLim
standby_heat < (standby_cool – nciOccDiff)
standby_heat <= nciHtgSptHiLim
standby_heat >= nciHtgSptLoLim
unoccupied_heat<(unoccupied_cool–nciUnoccDiff)
unoccupied_heat <= nciHtgSptHiLim
unoccupied_heat >= nciHtgSptLoLim
*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 point supported by
Receive Heartbeat has a separate timer associated with it.
The value of 0 disables this feature.
Supported Variables
nviApplicMode
nviAuxHeatEnable
nviComprEnable
nviEnergyHoldOff
nviOccSchedule
nviOccSensor
nviSetptOffset
nvoSpaceTemp
Room Sensor
Setpoint Adjust
Enable/Disable
nciLocSptEnable 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 the
setpoint control from a room sensor and enables the setpoint
control from the network.
Supported Values
0 = Disabled
1 = Enabled
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 identier 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 ofine).
