摘要

1. Method for regulating the three-phase current output of a temperature-controlled electrical sauna heating device (1), in dependency upon a nominal/actual temperature difference of a sauna room, by means of three regulatable relays (11, 12, 13), whereof each one switches a phase (U, V, W) and all of which, during a first method stage, are triggered at the first time of heating-up, in order to achieve the full heat output, and after reaching the nominal temperature for the first time, during a second method stage, however, only one or two of the relays (11, 12, 13) are triggered, for maintaining the nominal temperature value, characterised in that during the second method stage, for maintaining the nominal temperature value, in each case one or two relays (11, 12, 13) are triggered in cyclic sequence.
