Unit Information Tab
Space Temp:
The temperature, as reported by the zone sensor.
Active Setpoint:
The active (or actual) setpoint currently used by the VAV VV550 Controller. Can
be either Heating or Cooling depending on operating mode.
Primary Air / Discharge Air Temperature:
Shows the auxiliary temperature input.
Note:
This will be defined in configuration as either Primary Air or Discharge air temperature
depending on unit control strategies. See Configuration section for more details.
Airflow:
Measured in CFM. When a valid flow value is present, the controller operates under
pressure independent control. If after an airflow sensor failure, the airflow returns to the valid range
(airflow value greater than 10% of configured nominal airflow), the controller automatically
resumes pressure independent control. When the communicated airflow setpoint is invalid, the
flow sensor has failed, or calibration has failed, the controller closes the air valve if the configured
