Abstract
A fluid delivery control system including a rotatable flow control member to provide a flow control signal to a controller and a rotatable temperature control member to provide a temperature control signal to a controller.
Claims15
A fluid delivery control system comprising:
- a first fluid control valve;
- a first electric actuator operably coupled to the first fluid control valve;
- a controller in electrical communication with the first electric actuator;
- a user interface including a flow control member and a temperature control member configured for manual movement by a user;
- the flow control member in electrical communication with the controller, the flow control member supported for rotation about a rotational axis and configured to provide a flow control signal to the controller in response to rotation;
- the temperature control member in electrical communication with the controller, the temperature control member coaxially aligned with the flow control member, supported for rotation about the rotational axis, and configured to provide a temperature control signal to the controller in response to rotation relative to the flow control member;
- and
- wherein the controller is configured to cause the first electric actuator to adjust a fluid flow rate in response to the flow control signal and to adjust a fluid temperature in response to the temperature control signal.

A fluid delivery control system comprising:
- a flow control member supported for rotation by manual input from a user;
- a flow potentiometer operably coupled to the flow control member and configured to generate an electrical flow control signal in response to rotation of the flow control member relative thereto;
- a temperature control member supported for rotation relative to the flow control member by manual input from a user, the temperature control member being coaxially aligned with the flow control member;
- and
- a temperature potentiometer operably coupled to the temperature control member and configured to generate an electrical temperature control signal in response to rotation of the temperature control member relative thereto.
