A method and a control panel are described for facilitating the control of a bathing unit system so that the bathing unit system is caused to transition between operating in accordance with a first operational mode to operating in accordance with a second operational mode. A control signal is generated in response to a unitary user input event performed by a user at a control panel of the bathing unit system, the control signal conveying an ambiance activation command associated with a specific ambience setting, the generation of the control signal comprising selecting the specific ambience setting from a set of ambience settings stored in a memory device. The control signal is then transmitted from the control panel to the controller over a communication link where it is processed to cause the bathing unit system to transition from being in the rest mode to operating in accordance with the specific ambience setting. The method and a control panel may allow simplifying the control of the bathing unit system in order to achieve a desired total effect by allowing a user to cause the bathing unit to operate in accordance with an ambience setting by way of a unitary user input event performed at the control panel.
