Abstract
A diagnostic method for verifying the proper functioning of a fluid flow control device of a fluid system, the method including determining whether at least one pressure sensor is functional and if the at least one pressure sensor is considered functional, determining whether a bypass valve is functional and if the bypass valve is considered functional, determining whether at least one flow sensor is functional, if the at least one flow sensor is considered dysfunctional, a flow sensor fault is raised; and otherwise if the at least one pressure sensor is considered dysfunctional, using the at least one flow sensor to determine whether the bypass valve is functional, if the bypass valve is considered functional, determining whether at least one pump is functional, a pump alert is raised if the at least one pump is considered dysfunctional.
