The function adapts the refrigeration system’s suction pressure so that it will not become so low that
the most heavily loaded refrigeration appliance is unable to maintain the required temperature.
The procedure is that the gateway constantly makes enquiries with the selected refrigeration
appliances following which it transmits signals to the compressor control.
