摘要： A beverage preparation machine includes a thermal conditioning device, such as a heater or cooler. The thermal conditioning device contains a control unit for controlling a start-up phase of the thermal conditioning device from a temperature of inactivity to an operative temperature. The control unit includes a controller with a start-up profile for starting-up the thermal conditioning device, and the start-up profile has at least one parameter. The controller has a self-learning mode for adjusting the at least one parameter. A temperature sensor is connected to the controller for measuring a temperature of the thermal conditioning device. The self-learning mode causes the controller during a start-up phase to: calculate a ramp value representative of a rate of change in temperature during the start-up phase of the thermal conditioning device; adjust the at least one parameter as a function of the adjusted ramp value; and use the adjusted at least one parameter for a remainder of the start-up phase.
