Input Network Variables (nvi’s) Description
Parameter
Variable Name
Function
Room
Temperature
network input
SNVT_temp_p
nviSpaceTemp
This input network variable provides a network remote temperature
value to the thermostat. When linked of written to, the internal
temperature reading (internal sensor) is no longer used.
Valid Range: 40 to 122°F (-40 to 50°C)
Default Null (release) Value: 621.81°F (327.67°C or 0x7FFF)
This network variable is subject to the Receive HeartBeat Time,
nviRcvHrtBt.
Outdoor Air
Temperature
network input
SNVT_temp_p
nviOutdoorTemp
This input network variable provides outdoor air temperature
information to the thermostat from a network value temperature
value. The device will automatically display the value on its display
when linked.
Valid Range: 40 to 122°F (-40 to 50°C)
Default Null (release) Value: 621.81°F (327.67°C or 0x7FFF)
Occupied
Cool & Heat
Setpoints
network Input
SNVT_temp_p
nviSetpoint
This input network variable is used to allow the occupied
temperature setpoints only to be changed via the network from a
single analog value. (Note: the Stand-By and Unoccupied setpoints
are not changed). The corresponding heating and cooling values
are derived from the minimum deadband configuration value
Default Null Value: 621.81°F (327.67°C or 0x7FFF)
Ex. If the minimum deadband configuration value = 2 °F and
nviSetpoint = 70°F.
•
The resulting Occupied heating setpoint will equal 69 °F which is
derived from 70 °F minus _ the minimum deadband configuration
value of 2 °F
•
The resulting Occupied cooling setpoint will equal 71 °F which is
derived from 70 °F plus _ the minimum deadband configuration
value of 2 °F
Room
Humidity
network input
SNVT_lev_percent
nviSpaceRH
This input network variable is the measured room humidity in
percent monitored by the thermostat.
Valid Range: 5 to 90%
Default Null Value: +163.835 (0x7FFF)
This network variable is subject to the Receive HeartBeat Time,
nviRcvHrtBt
