A method of controlling a refrigerated merchandiser including a plurality of display case modules each having a separate refrigeration circuit with a compressor and an evaporator. The method includes selectively starting and stopping a first compressor of a first refrigeration circuit having a first evaporator associated with a first display case module to regulate a temperature in a product display area of the first display case module, and selectively starting and stopping a second compressor of a second refrigeration circuit having a second evaporator associated with a second display case module to regulate a temperature in a product display area of the second display case module. The method also includes controlling the first refrigeration module and the second refrigeration module based on a heat load of the merchandiser and a predetermined number of start/stop cycles of each of the first compressor and the second compressor within a given time period.
