This is an indicator that the static pressure set point is too high 2.
Temperature humidity dew point co voc s pressure and low temperature limit detection.
The static pressure probe is designed to pick up static pressure in a duct plenum air handler or other hvac equipment.
The probe has two orifices vertically opposite each other that cancel out any airflow induced errors.
