Parameter Variable Name Function
Supply
Temperature network output
SNVT_temp_p
nvoDischAirTemp This output network variable is used to monitor the temperature
of the air that leaves the Space Comfort Controller
Valid Range: -40 to 122°F (-40 to 50°C)
The value 621.81°F (327.67°C or 0x7FFF)will be sent as an
invalid value in case of a sensor failure.
This output network variable is used to indicate the actual
occupancy mode of the unit. This information is typically reported
to a supervisory controller or provided to another Space Comfort
Controller to coordinate the operation of multiple units
Valid Range:
0 = OC_OCCUPIED
1 = OC_UNOCCUPIED
2 = OC_BYPASS
1
Occupancy network output
SNVT_occupancy
nvoEffectOccup
3 = OC_STANDBY – Not Used
NOTE : OC_BYPASS can be initiated by either nviOccManCmd or a
local input. NvoEffectOccup will only be in OC_BYPASS for the
duration of the ToccTime (nciGenOpts), until reinitiated by either a
transition of the local input or an update to nviOccManCmd.
This network variable output is used to report the Space Comfort
Controller inputs’ and outputs’ status.
