4. Now, as described under 5.4.2, set the individual values for temperature, air flap position
etc. which you want the appliance to operate at. For universal ovens UN/UF and incubators
IN/IF, the set values can be changed while the timer elapses. The changes are effective im-
mediately. For sterilisers SN/SF, parameters cannot be changed while the timer elapses.
For universal ovens UN/UF and incubators IN/IF, you can choose if the timer should run
setpoint-dependent or not in the Setup – this determines if the timer should not start
until a tolerance band around the set temperature is reached or if it should start right after
activation (see page 38). If the timer runs setpoint-dependent, this is indicated by the
symbol in the timer display. symbol in the timer display.
When the timer has elapsed, the display shows 00h:00m. All func-
tions (heating etc.) are switched off. If a fan had been active, it will
keep on running for a short safety period. In addition, an acoustic
alarm sounds, which can be turned off by pressing the confirma-
tion key.
To deactivate the timer, open the timer display by pressing the
activation key again and then turning the turn control to reduce
the timer setting until --:-- is displayed. Confirm with the confirma-
tion key.
