Description
Network Configuration Property Inputs (NCIs)
HVAC Unit Type
Identifier
nciHVACType
SCPThvacType
0 to 9
Default: 3
No
Defines the primary application and equipment type for the
unit controller.
Do not modify this configuration 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
Local Bypass Time
Setpoint
nciBypassTime
SCPTbypassTime
0, 30 to 120 min
Default: 120 min
No
Defines the amount of time that the unit can be in the Bypass
mode initiated by the Timed Override button. Pressing the
Timed Override button 4-9 seconds sets the bypass timer to
the maximum nciBypassTime value. The value of 0 disables
this feature.
Location
nciLocation
SCPTlocation
32 Characters
No
Provides descriptive physical location information for the unit.
Minimum Send Time
nciMinOutTm
SCPTminSendTime
0 to 6553.4 sec
Default:0
(Disabled)
No
Minimum period of time between automatic network variable
output transmissions. It limits network traffic when output
network variables are frequently changing. The value of 0
disables the timer.
Supported Variables
nvoBrownout
• nvoDischAirTemp
• nvoEWT
• nvoLocalSpaceTmp
• nvoLWT
• nvoSpaceTemp
• nvoSuctionTemp1
• nvoSuctionTemp2
Occupied Setpoint
Differential
nciOccDiff
UCPToccDiff
1 to 5°F
0.55 to 2.78°C
Default:
1ºF / 0.55ºC
No
Sets the Occupied and Standby Setpoint hysteresis to then
determine the Effective OFF setpoints.
Interaction Rules
• nciOccDiff < (occupied_cool – occupied_heat)
• nciOccDiff < (standby_cool – standby_heat)
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

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).
