The display remains on for 3 sec.
2.5 Standby
If no key is pressed within 30 seconds, the oven
switches to the “Standby” mode.
The following are displayed in this mode:
- Upper display: Current temperature,
- Lower display: Current time.
At the same time, the brightness of the displays and
the LEDs is reduced.
Press any key to exit the standby mode.
The unit does not switch to the standby
mode while the oven is heating, during wait-
ing phases prior to heating, or while values
are being entered.
2.6 Mains Power Failure
Detection
The controller is equipped with a mains power failure
detection function which activates to overcome brief
power outages or if the main power switch is acciden-
tally switched off.
If the power supply fails for less than 10 minutes
during heating, the controller will continue from the
point in the program at which the power failed.
The timer is battery-buffered and may react to a pow-
er failure with a delayed start. The casting time will be
recalculated to reflect this.
The heating programme will not be restart-
ed if power is not restored until after the
programmed casting time has passed!
