Bathing system controller having abnormal operational condition identification capabilities

Abstract From the Canadian patent

A controller suitable for identifying malfunctions in a bathing system is provided. The controller includes a plurality of actuators associated with respective bathing unit components in the bathing unit system. During normal operational conditions the actuators are configured for causing bathing unit components to acquire either one of the actuated state or the non- actuated state. In one aspect the controller can detect a malfunction in an actuator based in part on a measured reaction time associated with the actuator. In another aspect the controller can detect a malfunction in an actuator based on an expected measurement and an observed measurement the expected measurement depending …
