Abstract
A temperature control system may include a thermoelectric device, a controller electrically coupled to the thermoelectric device, a heat transfer structure thermally coupled to the thermoelectric device, and a temperature controlled medium thermally coupled to the thermoelectric device. The controller may be configured to sense a first value of an electrical characteristic of the thermoelectric device and to generate a first electrical control signal to pump heat through the thermoelectric device in response to sensing the first value of the electrical characteristic of the thermoelectric device. The controller may be further configured to sense a second value of the electrical characteristic of the thermoelectric device and to generate a second electrical control signal to pump heat through the thermoelectric device in response to sensing the second value of the electrical characteristic of the thermoelectric device.
