ABSTRACT:
The present invention provides a refrigerated merchandiser including a case defining a product display area. The product display area defines a highest temperature zone and a lowest temperature zone. The merchandiser includes a first product simulator positioned in the highest temperature zone of the product display area to generate a first signal representative of the temperature of products positioned in the highest temperature zone of the product display area, and a second product simulator positioned in the lowest temperature zone of the product display area to generate a second signal representative of the temperature of products positioned in the lowest temperature zone of the product display area. The merchandiser also includes a controller in communication with the first and second product simulators. The controller is operable to adjust an outlet temperature set point in response to the first and second signals from the first and second product simulators.
