Abstract
A beverage preparation machine (1) comprising a thermal conditioning device (71), such as a heater or cooler, said thermal conditioning device (71) comprising a control unit (4) for controlling a start-up phase of the thermal conditioning device (71) from a temperature of inactivity to an operative temperature, the control unit (4) comprising: a controller with a start-up profile for starting-up the thermal conditioning device (71), wherein the start-up profile has at least one parameter and the controller has a self-learning mode for adjusting the at least one parameter; and a temperature sensor connected to the controller for measuring a temperature of the thermal conditioning device (71); wherein 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; use the adjusted at least one parameter for a remainder of the start-up phase. A method for operating and calibrating the thermal conditioning device of such a beverage preparation machine.
