Output Network Variables (nvo's) Description

All output network variables will be updated no faster than the Minimum Send Time (nciMinOutTm)
configuration value, if used.
An output network variable will be transmitted immediately when its value has changed significantly.
Additionally, this variable will also be transmitted as a heartbeat output on a regular basis as dictated by the
Maximum Send Time (nciSndHrtBt) configuration value.

Function
This output network variable is used to monitor the effective
space temperature sensor that the Space Comfort Controller is
using for control. This output echoes the value of the input.
Valid Range: -40 to 122°F (-40 to 50°C)
The value 621.07°F (327.67°C or 0x7FFF) will be sent as an
invalid value in case of a sensor failure.
This output network variable is available to report the Space
Comfort Controller status. It combines the operating mode, the
capacity of heating and cooling used and an indication if any
alarms are present in the object.

This output network variable is used to monitor the outdoor air
temperature.
Valid Range: -40 to 122°F (-40 to 50°C)
The value 621.07°F (327.67°C or 0x7FFF) will be sent as an
invalid value in case of a sensor failure or if unconnected.
