WARNING
For safety reasons, a possibly set nocturnal change (own menu item
nocturnal change) is deactivated during the processing of the nominal
value!
If you need to make a nocturnal change, you must reactivate it after the
nominal value processing.
Note
Please note the following in the temperature control:
The heat radiation of the lighting and the outside temperature can affect
the water temperature. If there is no cooling, it is possible that the set-point
temperature is exceeded.
Depending on the difference between the desired and the current
temperature, the heaters or the cooling are switched. The following states
can occur:
Tubular heater and substrate heating on / Only substrate heating on / All off
/ Cooling only
ProfiLux 4 is programmed in such a way that the substrate heating takes
precedence over the tubular heater. This makes an optimal heating of the
substrate possible. The tubular heater is then switched on when the
substrate heater alone is no longer sufficient.
