With the temperature-dependent light reduction, it is possible to prevent your aquarium
from being further heated by the illumination on hot summer days. This feature is especially
useful when an existing cooling system cannot provide sufficient temperature reduction.
The following parameters can be set:
The determining Temperature sensor (for example, temperature 1 if you have
connected one temperature sensor. If you connected more than one, select the
sensor to be used for the measurement).
The Temperature excess minimal – If the nominal temperature is exceeded by this
value, then the reduction of the illumination intensity of the affected lamps begins,
adjustable from 1 °C up to 5 °C - this setting is only relevant for dimmable lamps!!
The Temperature excess maximal – If the nominal temperature is exceeded by this
amount, the lighting concerned is switched off completely, adjustable from 2 °C to 10
°C, must be at least 1 °C higher than the minimum temperature limit - this setting is
only relevant for dimmable luminaires!
The Shut off limit – If the nominal temperature is exceeded by this amount, non-
dimmable luminaires are switched off. A value between 1 °C and 10 °C is adjustable.
These lights are not switched on again until the programming of the corresponding
illumination run defines again a switch on (luminaire has been switched off according
to the programming, for example at night - and is switched on again, for example in
the morning). A drop in the temperature alone does not lead to a new switch-on,
which is particularly useful with gas discharge lamps, since these should not be
switched on and off continuously. This setting is only relevant for non-dimmable
luminaires!
Example for Dimmable Lamps
Nominal temperature = 26.0 °C, min. temperature excess = 2.0 °C, max.
temperature excess = 4.0 °C, this results in the following table
