Once energized, in no case should the compressor be restarted within less than 3 minutes. In the situation that memory
function is available, for the first energization, if the compressor is at stop before de-energization, the compressor will be
started without a 3-minute lag; if the compressor is in operation before de-energization, the compressor will be started with
