A method of operating a compartmentalized transport refrigeration system having first, second and third compartments respectively served by a host refrigeration unit and first and second remote refrigeration units. The method includes the steps of providing a first signal when either of the first and second remote refrigeration units is in a cooling cycle, cycling the host refrigeration unit between cooling and heating cycles to hold a selected set point temperature of a fresh load in the first compartment, in the absence of the first signal, and providing a predetermined null period between the heating and cooling cycles of the host unit when the first signal is present. In a preferred embodiment a prime mover for a refrigerant compressor is operable at a selected one of high and low speeds, with the method including the step of preventing high speed operation when any remote refrigeration unit is in a heating cycle.
