Indoor Airflow / Static Pressure

Static pressure is not requested for ductless highwall, cassette, or console systems. Ducted Fan Coil / AHU systems require static pressure readings.

Infinity/Evolution communicating control: use the service menu/blower assessment to collect these readings.

Requested system airflow from Infinity/Evolution User Interface (CFM) *

System static pressure from Infinity/Evolution User Interface / blower assessment *

Blower motor rpm *

Return static pressure (in. wc.) *

Supply static pressure (in. wc.) *

Static pressure after furnace / before coil (in. wc.) *

Static pressure after coil (in. wc.) *

Total external static pressure (TESP) (in. wc.) *

Calculated from return + supply static pressure.

Calculated indoor airflow (CFM)
