When at least one of the light sensors is plugged-in, the maximum temperature of the chamber is limited
to 60 °C. If this temperature is reached due to an excessively high temperature set-point or to an error,
the message “ LIGHT SENSOR 60 °C!” is displayed. As soon as the unit has cooled down to a value of
59 °C or below, the message disappears.
