Description
Network Conguration Property Inputs (NCIs)
Brownout Reference
Setpoint
nciBrownoutRef UCPTbrownoutRef
25 to 1023 counts
Default: 400
No
Detects a unit controller brownout condition. A
brownout condition occurs when nvoBrownout < 80% of
nciBrownoutRef, and clears when nvoBrownout > 90% of
nciBrownoutRef.
Only perform the calibration procedure if the unit controller
24VAC voltage is within normal operating parameters. A
password of 1023 is required.
Compressor Low
Pressure Alarm Delay
nciLowPresAlmDly UCPTlowPresAlmDly
0 to 120 sec
Default: 30 sec
No
Species the time delay between the Low Pressure input and
compressor(s) alarm generation.
Compressor Low
Suction Temperature
Protection Differential
nciLowTmpProtDif UCPTlowTmpProtDif
2 to 15°F
1.11 to 8.34°C
Default:
8°F / 4.44°C
No
nciLowTmpProtDif is added to the selected Compressor
Low suction Tdemperature SP (nciLowTempProt or
nciLowTempProtGL) to determine the setting at which the
alarm clears.
Compressor Low
Suction Temp
Protection SP for
Glycol
nciLowTempProtGL UCPTlowTempProtGL
0 to 50°F
-17.78 to 10°C
Default:
6.5ºF/-14.16ºC
No
Temperature at which a Compressor Low Suction alarm
occurs in the Heating mode when the loop uid is glycol.
nciLowTempProtGL is enabled by the unit controller JP3
jumper in the shorted position, which selects glycol.
nciLowTempProtGL does not apply to the dehumidication
and cooling modes, which use a xed 28ºF low temp
threshold regardless of the loop uid type.
Compressor Low
Suction Temp
Protection SP for
Water
nciLowTempProt UCPTlowTempProt
0 to 50°F
-17.78 to 10°C
Default:
28ºF/-2.22ºC
No
Temperature at which a Compressor Low Suction alarm
occurs in the Heating mode when the loop uid is water.
nciLowTempProt is enabled by the unit controller JP3 jumper
in the open position, which selects water.
nciLowTempProt does not apply to the dehumidication and
cooling modes, which use a xed 28ºF low temp threshold
regardless of the loop uid type.
Compressor
Minimum OFF Timer
nciMinCompOffTmr
UCPT
minCompOffTmr
0 to 1200 sec
Default:* 360 sec
No
A countdown timer that denes the minimum period of time a
compressor must remain OFF before it is allowed to turn ON
again.
*Default value of 180 applies to the following:
• SmartSource (Series2) v5.0
• Ennity Large Two Compressor (SS2C) v1.0
Compressor
Minimum ON Timer
nciMinCompOnTmr
UCPT
minCompOnTmr
120 to 1200 sec
Default: 180 sec
No
A countdown timer that denes the minimum period of time a
compressor must remain ON before it is allowed to turn OFF
again.
Fourth Stage Heating
Setpoint Differential
nciStg4SptDiff UCPTstg4SptDiff
1 to 10°F
0.55 to 5.56°C
Default:
6ºF / 3.33ºC
No
Determines the Fourth Stage Heating ON setpoints from the
Third Stage ON setpoints for SmartSource (Series2) units
controlled by room sensors.
HVAC Unit Type
Identier
nciHVACType SCPThvacType
0 to 9
Default: 3
No
Denes the primary application and equipment type for the
unit controller.
Do not modify this conguration property.
Supported Values
0 = HVT_GENERIC
1 = HVT_FAN_COIL
2 = HVT _VAV
3 = HVT_HEAT_PUMP (Default)
4 = HVT_ROOFTOP
5 = HVT_UNIT_VENT
6 = HVT_CHILL_CEIL
7 = HVT_RADIATOR
8 = HVT_AHU
9 = HVT_SELF_CONT
Hydronic Cooling ON
Setpoint
nciHydroClgOnSpt UCPThydroClgOnSpt
50 to 70ºF
10 to 21.12ºC
Default:
55ºF / 12.78ºC
No
Species the Entering Water Temperature (EWT) Hydronic
Cooling setpoint for units with a waterside economizer.
Hydronic cooling is enabled if the EWT is below the value of
nciHydroClgOnSpt. It is allowed to operate in conjunction
with compressor cooling. If the EWT drops below the xed
value of 35ºF, hydronic cooling is disabled.
Hydronic Heating ON
Setpoint
nciHydroHtgOnSpt UCPThydroHtgOnSpt
70 to 158ºF
21.11 to 70ºC
Default:*
90ºF / 32.22ºC
No
Species the Entering Water Temperature (EWT) Hydronic
Heating setpoint for units with a hydronic heating coil.
Hydronic heating is not allowed to operate in conjunction with
compressor heating.
*Default value: 70ºF / 21.12ºC
• SmartSource (Series2) v6.1 and older
• Ennity Large Two Compressor (SS2C) v1.1 and older
