Analog, Binary, and Multistate Screens

Use the Analog, Binary, and Multistate screens to view input, output, and value points. These three
categories are presented in expanding boxes that stretch across the middle of each screen and are
defined from the factory.
Note: For field use of spare points, refer to the Appendix section of the Tracer BACnet VAV

Airflow Setpoint (Active): Displays the active airflow setpoint. The airflow setpoint will be
determined based on the heat cool mode status, and the required heating or cooling capacity.
Space CO2 Concentration: CO
The controller compares the space CO
determines the demand ventilation rate of the zone. The resulting ventilation rate is called the
effective ventilation setpoint. The effective ventilation setpoint is the outdoor airflow required
to provide ventilation. It is used to calculate the ventilation ratio of the zone.
Space Temperature: The temperature, as reported by the zone sensor.
Space Temperature (Active) Setpoint: The active (or actual) setpoint currently used by the
Tracer UC210 controller. Can be either Heating or Cooling depending on operating mode.
Space Temperature Setpoint BAS: Shows the setpoint being communicated to the VAV unit
from a BAS system.
Space Temperature Setpoint Local: Displays setpoint from local zone sensor.
Space Temperature Setpoint Default: Displays default configured setpoint.
Discharge Air Temperature: Shows the discharge air temperature input, which is the
temperature of the air leaving the VAV box.
DA Temperature Setpoint BAS: Displays communicated discharge air temperature setpoint, if
valid, when discharge air temperature control reset is enabled.
Ventilation Ratio: Required ratio of OA to primary air to meet zone ventilation need.
Ventilation Setpoint: Arbitrated final value of the zone ventilation requirement.
Air Flow Stpt Active Min: Displays active minimum flow setpoint.
Note: The UC210 may not be using the minimum flow setpoint if space conditions require
more airflow).
Air Flow Stpt Active Min Source: Displays the current minimum flow setpoint source.
Supply Fan Status: Indicates current fan On/Off status, or None if no fan present.
Air Valve Position Command: Indicates desired air valve position.
Heat Output Secondary Status: Indicates Reheat Capacity Status in percentage.
