Network interface used
Advanced network interface can be obtained when thermostats are fully integrated to the reservation system.
In these cases, the occupancy network commands state enumerations text presented by a front end system can be expanded to
better represent the nature of the application.

= Local PIR Occupancy
At initial power-up, when the thermostat 24 Vac power supply is applied; if there is no occupancy network command received by
the thermostat and if the PIR devices do not detect any movement, the initial occupancy of the zone will be stand-by mode.
Occupied state network command
At any time, an occupied network command will always force the local zone to be in occupied mode and to use the occupied
setpoints.
Unoccupied state network command
At any time, an unoccupied network command will always force the local zone to be in unoccupied mode and to use the
unoccupied setpoints. If the thermostat local override function is not locked out by configuration, the local user may initiate a
temporary local override to occupied as dictated by the temporary occupancy time configuration parameter setting.
Local occupancy state network command
If previously in unoccupied mode when the thermostat receives a local occupancy state network command, the local PIR
occupancy loop will now be enabled. If the PIR devices do not then detect any movements, the occupancy of the zone will be
stand-by mode.
As soon as the PIR device detects a movement or motion, the occupancy status switches to occupied and the occupied setpoints
are used. The room will then be in occupied mode until a door toggle is detected.
If a door toggle is detected, then the room switches to stand-by mode and the stand-by setpoints are used. If any occupants are
left in the room, local movements must be seen to resume the occupied mode.
At anytime, if the PIR device detects a local movement or motion, the occupancy status switches to occupied and the occupied
setpoints are used.
The local zone never goes into unoccupied mode and the unoccupied setpoints are never used.
