Network Variable and Configuration Property Definitions
nvoVoltageX
Voltage per phase—compressor X,* UNVT_3phase_volt
nvoVoltageA
nvoVoltageB
nvoVoltageC
nvoVoltageD
nvoVoltageE
nvoVoltageF
This network variable provides a measurement of the three phase voltages at
compressor X (*where X is A, B, C, D, E, or F depending on the network variable.) There
are separate network variables for each compressor.
Configuration Property Definitions
The configuration property definitions (implemented as configuration parameters) are
listed alphabetically by nci name.
nciBaseLdgReq
Default Value for nviBaseLdgReq, SNVT_switch, level 1
This configuration property sets the default value for the base loading request
(nviBaseLdgReq) of the chiller, unless the configuration property nciDefaults = 1. When
nciDefaults = 1, the UC800 controller ignores the BAS value and chooses from other
available requests (external or front panel) based on internal arbitration rules.
• Range: Same as nviBaseLdgReq
• Default: Invalid (0xFF, 0xFF)
• UCPT reference: None
nciBaseLdgSetpt
SNVT_lev_percent, level 1
This configuration property sets the default value for the base loading setpoint
(nviBaseLdgSetpt) of the chiller, unless the configuration property nciDefaults = 1. When
nciDefaults = 1, the UC800 controller ignores the BAS value and chooses from other
available setpoints (external or front panel) based on internal arbitration rules.
• Range: Same as nviBaseLdgSetpt
• Default: Invalid (0x7FFF)
• UCPT reference: None
