Abstract
A method of operating a rethermalizing station having an induction coil includes detecting a temperature of a food pan, selecting, based on the temperature of the food pan, a selected mode from a set comprising a low temperature mode, an over temperature mode, and a keep warm mode, and varying, in accordance with the selected mode, an output power of the induction coil by controlling a supply current to the induction coil to vary between a first nonzero current value and a second nonzero current value.

A method of operating a rethermalizing station comprising a three-dimensional induction coil, the method comprising:
- obtaining a detected temperature of a food pan;
- performing a comparison of the detected temperature and a targeted temperature;
- and
- varying, based on the comparison, an output power of the three-dimensional induction coil between a first nonzero output power value and a second nonzero output power value by controlling a supply current to the three-dimensional induction coil to vary between a first nonzero current value and a second nonzero current value.
