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 fluid.
Unit controller software v3 .1 and newer
• Temperature at which a Compressor Low Suction alarm
occurs in Heating mode when the loop fluid is glycol.
• nciLowTempProtGL does not apply to the
Dehumidification and Cooling modes, which use a fixed
28ºF low temp threshold regardless of the loop fluid
type.
Unit controller software v3 .0 and older
• Temperature at which a Compressor Low Suction alarm
occurs when the loop fluid is glycol.

A countdown timer that defines the minimum period of time a
compressor must remain OFF before it is allowed to turn ON
again.
Compressor
Minimum ON Timer
nciMinCompOnTmr
UCPTminCompOnTmr
120 to 1200 sec
Default: 180 sec

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

nciCoolIntStgTmr
UCPTcoolIntStgTmr
120 to 1200 sec
Default: 300 sec
No
A countdown timer that defines the minimum period of time
between turn-on of the cooling stages.

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 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).
