A method for controlling a substrate temperature in a substrate processing system includes determining a temperature difference between the substrate temperature before the substrate is loaded onto a substrate support device and a desired temperature for the substrate support device and, during a first period, controlling a thermal control element to adjust the temperature of the substrate support device to a temperature value based on the temperature difference. The temperature value is not equal to the desired temperature for the substrate support device. The method further includes loading the substrate onto the substrate support device after the first period begins and before the temperature of the substrate support device returns to the desired temperature and, during a second period that follows the first period, controlling the temperature of the substrate support device to the desired temperature for the substrate support device.

A closed-loop temperature controller employing at least two sensors: a control temperature sensor and a safety sensor at the heat-transfer element. The heat-generating element is separated from the controlled mass/volume by a transport delay so that the mass or volume that is being heated or cooled is located in a vessel which is located remotely from the heat-transfer unit. Thermally conducting fluid flows through a conduit that connects the heat-transfer unit to the vessel. Upon fluid flow interruption or control sensor removal, the temperature controller quickly detects thermal runaway before the safety sensor has reached the critical temperature. In heated systems, the temperature controller will therefore minimize direct damage and/or overshoot damage caused by excessive heat. It will also maintain the heater's output at an elevated, but non-damaging level to enable a fast recovery to the original setpoint temperature after the nonlinearity subsides.

A cooking appliance is adapted to perform either as a single large fan-forced convection oven capable of cooking a larger food, or as smaller independently-operable fan-forced convection ovens each capable of cooking smaller foods. Features of the cooking element arrangement provide faster, more efficient, and higher quality results regardless of the size and amount of food being cooked.
