8 Warnings
8.1 Flashing display
The display will flash if the temperature in the aquarium deviates from
the set value by more than + 3 or – 3 °C.
Check immediately:
• Are the heating systems working correctly?
• Is the temperature sensor secured correctly?

The acoustic alarm can be activated in addition to the visual alarm.
This is expedient when the Duomat is installed in the base cabinet of
the aquarium, for example:
• To activate the acoustic alarm: Press key - LED goes ON
• To deactivate the acoustic alarm: Press key again - LED goes OFF

10.1 Replacing the fuses
If one of the connected heating system fails to work although the
corresponding LED indicates that it is on, either the heating system or
the fuse is defective.
• Checking the fuse: Connect standard table lamp to the socket on
the power unit. Set required temperature sufficiently high for the
heating system to be activated. If the lamp does not light up, the
fuse is defective.
• Replacing the fuse: Disconnect the Duomat from the mains.
Unscrew fuse holder and remove defective fuse. Fit new fuse
of the same type (from electrical retailer) and screw fuse holder
back into place.
10.2 What will happen in case of a power failure?
In case of a power failure, all programmed settings and functions will
be retained in the internal permanent memory. As soon as the power
supply to the Duomat is resumed, it will automatically perform the
necessary control actions to restore the temperature in the aquarium
to the set value.
