Ja, soweit ich weiß, wurden vorletztes Jahr noch andere Regler mit blauen LEDs verbaut, aktuell ist aber die mit den roten LEDs und wenn ich mich richtig erinnere, gab es Wärmeprobleme mit dem alten Regler (AKO?)
edit:
Unfortunately, this machine cannot be called the
Expobar Brewtus III as it is called in some other
world markets, hence the rather uninspiring name
used in this review. This is an update of the
previous Brewtus II dual boiler machine. The
previous machine did suffer from problems
mainly the AKO temperature controller failing and
an inappropriate expansion valve (OPV), these
came to light some months after the review. The
Brewtus II also had some quality control issues I
thought were one off’s, but this proved not to be
the case.
