3.4.4.1 Switching behaviour of the fans

The fans have different switch-on and switch-off points. The switching point for the
switch-on temperature ① is adjustable. The hysteresis for the switch-off temperature ②
cannot be changed. The switching behaviour of the fans depends on the heat sink and
interior temperature.
