nviApplicMode (nviFP05)
This network variable input is used to coordinate the Space Comfort Controller with any supervisory
controller.
If a mode that is not supported by the unit controller is requested, the unit controller will use
HVAC_AUTO.
The nviApplicMode overrides the local control of nvoHeatCool.
Refer to nvoHeatCool(nvoFP03) for more information.

0 = HVAC_AUTO (Mode determined by unit)
1 = HVAC_HEAT (Use heat setpoints)
2 = HVAC_MRNG_WRMUP (Morning warmup)
3 = HVAC_COOL (Use cool setpoints)
4 = HVAC_NIGHT_PURGE (Free cooling)
5 = HVAC_PRE_COOL (Morning cooldown)
6 = HVAC_OFF (No unit operation allowed)
7 = HVAC_TEST (Special test mode, manufacturer-defined)
8 = HVAC_EMERG_HEAT (Emergency heat)
0xFF = HVAC_NUL (same as HVAC_AUTO)

HVAC_AUTO
nviFanSpeedCmd (nviFP06)
This input network variable is used to override the local fan speed operation.
The system can be configured to use this variable as a 3 speed fan override or a variable speed fan
override.
To use this input as a 3 speed fan override, the Boolean constant nviFanSpeedCmdDigital
(nciCb01_124/ConstantBool3) must be set to true.
When in 3 speed fan operating mode, the requested speed (Off, 1,2,3,Auto) are linked to the values of
nciFanSettings.FanSpeed1Level,FanSpeed2Level and FanSpeed3Level (nviFP39).

FanSpeed1Level, FanSpeed2Level or FanSpeed3Level based on the received information from nvi-
FanSpeedCmd.
When in variable fan speed operating mode, if not in auto mode the fan output will be set to the value
received by nviFanSpeedCmd.
