Configuration Tables
| Doorway / InSite Code | Label | Description | Units | Default Value | Range |
| C1 | SACT | Sensor Action; sets pre-processing for temperature input and
selects external input modes. 0: use local sensor unless remote hardwired sensor connected (see use of nviRemoteTemp for Open systems) 1: average of valid sensor values 2: maximum of valid sensor values 3: minimum of valid sensor values 4: use remote sensor as Occupation input , VFC shorted is occupied 5: use networked temperature (nviRemoteTemp) if valid, else remote hardwired if valid, else local 6: use remote sensor as Occupancy / standby input, VFC shorted is occupied with close control. open circuit is standby or non-occupied according to zone occupancy pattern 7: use remote sensor as Occupation input, internal occupancy AND external VFC shorted is occupied, external VFC open is non-occupied |
