• The monitoring functions of the electronics
during an interruption of the power supply for at
least 48 hours are maintained by an integrated
rechargeable battery.
• This battery is automatically charged when the
appliance is connected.
• If the capacity of the battery is no longer
sufficient to take over the control function, the
error message “BAT.1 LOW/FAIL” appears on the
display.
• At the first starting up it may happen that the
message „BAT.1 LOW/FAIL” appears. The message
will disappear as soon as the battery is charged.
• The battery should be pre-emptively replaced
every 2 years. This replacement must only be
carried out by a recognised service technician.
Before dismantling the battery the appliance
must be switched off and the plug pulled out.
• The battery is a lead-acid storage battery that
must be disposed of separately in the case of a
fault.

• There are two terminals with three floating
contacts on the back of the unit that can be used
to trigger an additional external alarm (visual or
audible).
• The upper contacts correspond to temperature-
and door-alarm, the lower contacts correspond
to a powerfail-alarm.
• Pressing the ENTER-key in an alarm situation
only switches off the internal audible alarm. The
key does not interfere with the external alarm.
The external alarm signal is only switched off
once the cause of the alarm has been eliminated.
• A voltage of between 12V DC and a maximum of
250V AC can be connected at the contacts. The
maximum load must not exceed 8A. The
minimum power rating is 100mA / 5V.
