Abstract
There is provided a resistive actuation unit for activating a tub system an operation of which is controlled by a controller. The actuation unit comprises at least one switching device coupled to a body of the tub and in communication with the controller. The switching device comprises a first and a second resistive element, each of which having a resistive value, which changes upon a contact being made on the resistive element. The controller detects a change in resistive value of at least one of the first and the second resistive element. If the controller detects a change in the resistive value of the first resistive element only, the selected function of the tub system is activated. Otherwise, the controller determines that water contacted the second resistive element and the selected function is not activated.
