  • Page 29: Checking Indoor Air-Flow Rate

    4.3 CHECKING INDOOR AIR-FLOW RATE 4.3.1 ESTIMATING AIR-FLOW RATE USING EXTERNAL STATIC PRESSURE A common method of checking indoor is to measure the external static pressure that the air-handler is working against and then referring to the air-flow data in Section 3.12. Measuring external static pressure to a high degree of precision in the field is challeng- ing, so keep in mind that the air-flow rate determined by this method is an estimate, but is accurate enough for all practical purposes.

    4.5 SEQUENCE OF OPERATION 4.5.1 COOLING & HEAT PUMP HEATING MODES When the 2-stage thermostat calls for 1st stage of cooling or heat pump heating and the thermostat fan setting is set to the AUTO position, the G signal from the thermostat causes the Variabe Frequency Drive (VFD) to ramp the motor to the low speed air-flow level (37.5 Hz) which is 63% of full air-flow.
