Abstract

A system for controlling a flow rate through an HVAC component is provided. The system includes a controller communicably coupled with a potentiometer and an actuator configured to drive the HVAC component between multiple positions to affect the flow rate. The controller configured to determine an actuator position setpoint based on a flow rate setpoint, drive the actuator to the actuator position setpoint using a calculated travel period, and set a current actuator position based on a voltage signal received from the potentiometer upon stopping the actuator at an expiration of the calculated travel period.
