Table 6: Variable Definitions
Variable Name e
R = Read
W = Write
Description
nviCapLimit_x
W
Analog Value
Sets humidifier capacity limit (50-100%)
Example: 500 = 50%, 1000=100%
nvoCapLimit_x
R
Analog Value
Read Manual capacity (50-100%)
Example: 500 = 50%, 1000=100%
nviRHDem1_x
W
Analog Value
Writes channel 1 demand or %RH. Allows BAS control of output.
(0 - 100%). Unit must be configured to accept network demand.
Example: 500 = 50%, 1000=100%
nvoRHDem1_x
R
Analog Value
Reads channel 1 demand or %RH. Allows BAS control of output.
(0 - 100%). Unit must be configured to accept network demand.
Example: 500 = 50%, 1000=100%
nviSet1_x
W
Analog Value
Writes setpoint when humidifier is operating on
sensor/transducer controls. Acceptable values are 10 - 90 %.
Example: 500 = 50%, 900=90%
nvoSet1_x
R
Analog Value
Reads setpoint when humidifier is operating on
sensor/transducer controls. Acceptable values are 10 - 90 %.
Example: 500 = 50%, 900=90%
nviDisable_x
W
Binary Value
Allows for remote disable of humidifier.
0 = Run
1 = Disable
nvoDisable_x
R
Binary Value
Checks remote disable status.
0 = Run
1 = Disable
nviNetSensor_x
W
Binary Value
Configures unit to look for either hardwired controls or control
value written from building automation system.
0 = Hard wired controls
1 = Network controls
nvoNetSensor_x
R
Binary Value
Checks current control source.
0 = Hard Wired
1 = Network
nvoFault_x
R
Binary Value
Reads fault status.
0 = Normal operation
1 = Unit Fault
nvoSecurity_x
R
Binary Value
Checks status of security loop (on/off controls wired in series
between terminals 1 and 2 on the low voltage terminal strip).
Humidifier will only operate if loop is closed.
0 = Open
1 = Closed
nvoService_x
R
Binary Value
Checks service light status.
0 = Normal operation
1 = Service required, check humidifier display for information.
nviHum_Control_x
W
Analog Value
Change control type that humidifier is accepting.
Warning: Check physical control type before modifying.
0 = Demand signal
1 = On/Off signal
2 = Transducer (sensed %RH), humidifier uses proportional
algorithm
3 = Transducer (sensed %RH), humidifier uses proportional-
integral algorithm
