Abstract
A system and method for controlling refrigeration including a simulated product temperature sensor operable to measure a simulated product temperature from a refrigeration case and a transceiver in communication with said simulated product temperature sensor and operable to wirelessly transmit data. A receiver receives the wirelessly transmitted data and a controller in communication with the receiver controls the refrigeration system based upon the wirelessly transmitted data from the refrigeration case.
