Abstract
An updated operating speed for a fan of an air handler may be determined. The updated operating speed may depend on a target output volume for the air handler and an intermediate resistance value for a filter of the air handler. The intermediate resistance value may be determined by instructing the fan to operate at a first operating speed for a fixed period of time. During the fixed period of time, a pressure sensing system may sense an observed differential pressure measured across the filter. The observed differential pressure may correspond to the intermediate resistance value. The intermediate resistance value may be used to identify, from a set of filter loading values which may be retained in a filter loading data structure, the updated operating speed for the fan such that the air handler is capable of achieving the target output volume.
