A refrigerated container system is described that includes a wireless personal area network (WPAN) including a plurality of wireless sensor nodes and a coordinator node through which the sensors provide sensor data to a controller for the refrigerated container system. The wireless sensors and the coordinator incorporate a variety of features that ensure efficient utilization of battery life by preventing unintended pairing of sensors with other WPANs and excessive sensor signal processing arising from door chatter. Finally, pairing is performed without pressing a button on the wireless door sensor. Instead, the sensor's magnetic reed switch is enlisted to detect swiping of a magnet by a user to enter a pairing mode.

An oven temperature controller for regulating temperature to a temperature setpoint over a temperature range in an oven compartment comprising a microprocessor and memory storage means. The memory storage means stores temperature setpoint related information for temperature setpoints over the temperature range and this information is used by the microprocessor for establishing an upper control limit curve and a lower control limit curve. The upper control limit curve and lower control limit curve have no discontinuities over a majority of the temperature range and at least one of these curves is non-parallel to a temperature setpoint line, the temperature setpoint line formed in a stepwise linear manner between temperature setpoints as the temperature setpoint is varied over the temperature range.

A system and method for reducing the amount of electrical noise in a signal produced by a temperature sensor for an appliance which utilizes a running average calculation to provide a more accurate sensor reading in an inexpensive and efficient manner. Consecutive readings obtained by the sensor are digitized and stored in a circular buffer. A running average of the readings stored in the buffer is made upon each new reading and the concurrent erasure of the oldest reading.
