Maintenance - Carrier VAV Zone II Installation And Startup Manual

System Space AQ – The indoor air quality received over the network. -999 indicates no
value has been received and it will not be used.
System Cool Demand Level– The value received over the network and used by the
demand limiting function to expand the cooling setpoint.
System Heat Demand Level– The value received over the network and used by the
demand limiting function to expand the heating setpoint.
System Outdoor Air Temperature – The OAT received over the network.
System Occupancy – The status of the System Occupancy network point.

Point Name/Description
Unit
Occupancy Status – The controller's occupancy status as determined by a network
schedule, a local schedule, or a timed override.
Temp Compensated Start or Learning Adaptive Start – Indicates the type of optimal
start (if any) that is configured and whether the algorithm is active or inactive.
Space 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 space
temperature AV.
Airside Linkage – The space temperature from a linked terminal.
Locked Value –The controller's space temperature input has been manually locked at a
value.
ZS Sensor – A ZS sensor is connected to the controller's Rnet port.
Setpoint Adjustment – The amount that a user has adjusted the setpoints at a zone
sensor.
Effective Heat Setpoint – The current heating setpoint. May include offsets from
configured occupied/unoccupied setpoints resulting from Optimal Start to Demand
Limit.
Effective Cool Setpoint – The current cooling setpoint. May include offsets from
configured occupied/unoccupied setpoints resulting from Optimal Start to Demand
Limit.
