Abstract
Circuits for controlling an impeller in a fluid flow distribution system to achieve a target fluid flow are disclosed. The circuit to output a signal representative of a speed value (N) of the impeller derived from a stored power consumption value (W) and speed value (N) pairs to achieve the target fluid flow. The circuit to receive a power signal representative of an input power consumption value (W) of the impeller at the speed value (N) to input fluid to the fluid flow distribution system and to compare the value (W) represented by a power signal for the speed value (N) with the stored value (W) and impeller speed value (N) pairs to determine a least difference impeller speed value (N) of the stored pair comprising a least difference between the value (W) and the value (W). The circuit to output a speed signal representative of value (N).
