Network Conguration Property Inputs (NCIs)

Setpoints

nciSetpoints SCPTsetPnts

50 to 95ºF

Defaults:

See Description*

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)

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

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).
