Abstract: A method of monitoring the performance of a chiller system includes receiving a temperature sensor reading from a temperature sensor on an input channels at an analog-to-digital (A/D) converter interface. The temperature sensor reading is converted into a first value and then converted into an equivalent resistance value using a set of calibration parameters. A first set of configuration parameters are applied to the resistance value to compensate for inaccuracies in the conversion. The resistance value is adjusted based on an internal temperature parameter. A second set of configuration parameters is applied to the resistance value to account for sensor drift over time. A set of coefficient values related to the characteristics of the sensor are received and used to convert the adjusted resistance value into a temperature value. The resistance value and temperature value are transmitted to an external system for monitoring the chiller system.

Abstract: A housing component (500) for an electronic device (100) includes a rear wall (1526) with an exterior surface, a top Wall (1504), a ledge (1506) with an exterior surface, and an air outlet (1502) formed between the top wall (1504) and the ledge (1506). The ledge (1506) is positioned below the top wall (1504). The exterior surface of the ledge (1506) is positioned at an exterior angle less than 90° relative to the exterior surface of the rear wall (1526).
