Description
Network Conguration Property Inputs (NCIs)
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
Local Bypass Time
Setpoint
nciBypassTime SCPTbypassTime
0, 30 to 120 min
Default: 120 min
No
Denes 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 trafc 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 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).
