One RTCSmp HOIN induction generator can control up to four heat retaining plates. Hence, four configurations 
are available, ranging from one to four heat retaining plates. For each configuration, one temperature control 
switch controls up to two heat retaining plates. When two heat retaining plates are connected to one switch, both 
plates would be set to the same set temperature.
