SCPTsetPnts
50 to 95ºF

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)
• occupied_cool <= nciClgSptHiLim
• occupied_cool >= nciClgSptLoLim
• standby_cool > (standb nciOccDiff)
• standby_cool <= nciClgSptHiLim
• standby_cool >= nciClgSptLoLim
• unoccupied_cool>(unoccupinciUnoccDiff)
• 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
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 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 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).
