R: -50 to 150°F(-45.5 to 65.5°C)System Occupancy – The status of the System Occupancy network point. D:R:UnoccupiedUnoccupied/OccupiedMaintenanceNavigation: i-Vu® / Field Assistant: Properties > Control Program > MaintenancePoint Name/Description Default/RangeUnitOccupancy Status – The controller's occupancy status as determined by a networkschedule, a local schedule, or a timed override.R: Unoccupied/OccupiedTemp Compensated Start or Learning Adaptive Start – Indicates the type of optimalstart (if any) that is configured and whether the algorithm is active or inactive.R: Inactive/ActiveSpace Temp Source – The source of the controlling space temperature value.Options:Sensor Failure – No valid space temperature or sensor status = failed.SPT Sensor – An SPT sensor is connected to the controller's Rnet port.T55/56 – A T55, T56, or T59 sensor is connected to the controller's I/O terminals.Network – A network temperature sensor is bound to the controller's spacetemperature AV.Airside Linkage – The space temperature from a linked terminal.Locked Value –The controller's space temperature input has been manually locked at avalue.ZS Sensor – A ZS sensor is connected to the controller's Rnet port.R: Sensor FailureSPT SensorT55/T56NetworkAirside LinkageLocked ValueZS SensorSetpoint Adjustment – The amount that a user has adjusted the setpoints on a zonesensor.R: -20 to 20 °F(-11.1 to 11.1 °C)Effective Heat Setpoint – The current heating setpoint. May include offsets fromconfigured occupied/unoccupied setpoints resulting from Optimal Start to DemandLimit.R: _°F/C
