Claim 0:
1. A method for controlling a start-up phase of a thermal conditioning device of a beverage preparation machine, the method comprising:
loading a ramp value representative of a rate of change in temperature of the thermal conditioning device during a previous start-up phase;
determining a parameter of the start-up phase based on a start temperature of the thermal conditioning device, a stored operative temperature of the thermal conditioning device, and the loaded ramp value;
powering up the thermal conditioning device;
the thermal conditioning device comprising a controller that has a self-learning mode for adjusting the parameter;
determining that a temperature of the thermal conditioning device is not between a predetermined threshold temperature value and the stored operative temperature;
entering the self-learning mode when the temperature of the thermal conditioning device is not between the predetermined threshold temperature value and the stored operative temperature;
in the self-learning mode, measuring a ramp time duration for the thermal conditioning device to go from a first calibration temperature to a second calibration temperature;
calculating an adjusted ramp value based on the ramp time duration; and
adjusting the parameter based on the adjusted ramp value and continuing the start-up phase with the adjusted parameter.
