The controller is configured obtain one or more current operating signals related to the flow rate of the output stream produced by the mixer valve and compare each of the one or more current operating signals to a corresponding historical operating signal, the historical operating signal being an operating signal previously obtained by the controller, and to generate a diagnostic signal based on the comparison.

Abstract: A control system for one or more ablutionary devices includes a mixer valve having a first inlet and a second inlet configured to receive a supply of hot and cold water, and an outlet configured to output cold water, hot water or a mixture thereof as an output stream for suppling water to the one or more ablutionary devices downstream of the mixer valve; and a controller in communication with the mixer valve. The controller is configured to obtain a supply coupling setting that indicates which of the first and second inlets is to receive, or is receiving, hot water during operation of the control system and which of the first and second inlets is to receive, or is receiving, cold water during operation of the control system; and control the mixer valve according to one or more target output water properties and the supply coupling setting.

Abstract: A liquid dosing apparatus for dispensing a liquid from a container into a liquid stream of a shower, toilet, or tap includes an adapter, a dosing mechanism, a damping control system, and a dispensing outlet. The adapter is arranged to detachable receive the container. The dosing mechanism includes a dosing chamber and a movable member. The dosing mechanism is arranged to draw a set volume of the liquid into the dosing chamber on activation by moving the moveable member in a first direction. The damping control system is arranged to control a dispensing rate of the set volume of the liquid by controlling return speed of the moveable member. The damping control system is arranged to allow and control adjustment of the dispensing rate. The dispensing outlet is arranged to dispense the liquid into the water stream at the controlled dispensing rate.
