Description:
The TC500 had BACnet points to control the occupancy status of the device. This point has a fail-detect policy where it requires the value to be written periodically or else it will go back to a "default" value. This will be seen as the occupancy state going back to default after a period of 5 minutes.
Procedure:
- Set up a new BACnet tuning Policy
- Set the Max Write Time to 1 min
- For the BACnet point ni_NetSchCurrentState (MSV-1) set the tuning policy to that which was created above. (this will ensure that the point is updated within the fail-detect period and maintain the desired value)
