Protection SP for
Glycol
nciLowTempProtGL UCPTlowTempProtGL
0 to 50°F
-17.78 to 10°C
Default:
6.5ºF/-14.16ºC
No
nciLowTempProtGL is enabled by the unit controller JP3
jumper in the shorted position, which selects glycol as the
loop uid.
Unit controller software v3.1 and newer
• Temperature at which a Compressor Low Suction alarm
occurs in Heating mode when the loop uid is glycol.
• nciLowTempProtGL does not apply to the
Dehumidication and Cooling modes, which use a xed
28ºF low temp threshold regardless of the loop uid
type.
Unit controller software v3.0 and older
• Temperature at which a Compressor Low Suction alarm
occurs when the loop uid is glycol.

No
nciLowTempProt is enabled by the unit controller JP3 jumper
in the open position, which selects water as the loop uid.
Unit controller software v3.1 and newer
• Temperature at which a compressor Low Suction alarm
occurs in the Heating mode when the loop uid is water.
• nciLowTempProt does not apply to the Dehumidication

A countdown timer that denes the minimum period of time a
compressor must remain OFF before it is allowed to turn ON
again.

Minimum ON Timer
nciMinCompOnTmr UCPTminCompOnTmr
120 to 1200 sec
Default: 180 sec
No
A countdown timer that denes the minimum period of time a
compressor must remain ON before it is allowed to turn OFF
again.

50 to 95ºF
10 to 35ºC
Default:
95ºF / 35ºC
No
Maximum value of all Occupancy Heating setpoints. It also
species the maximum allowed value of the nvoSetpoint Long
Range Setpoint Adjust. The nciHtgSptHiLim must be greater
than nciHtgSptLoLim.
Heating Setpoint

nciHtgSptLoLim must be less than nciHtgSptHiLim.
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 identier 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 ofine).
