Abstract
A refrigerated merchandiser includes a sensor coupled to a case adjacent an air inlet. The sensor is in communication with a portion of a refrigerated airflow passing through the air inlet to sense a temperature of the airflow and to generate a signal indicative of an air return temperature. The merchandiser also includes a controller in communication with the sensor to receive the signal indicative of the air return temperature, the controller further in communication with a conductive film on a door and programmed to initiate a clearing interval to clear condensation from the door in response to the signal indicative of the air return temperature reaching a first predetermined temperature threshold.
