ADMIN
All data and settings that were preset by the manufacturer of the freezer appliance, such as the permitted or possible set
point limits for the refrigeration compartment temperature, are stored under the "ADMIN" user profile.
The operator cannot modify the settings in this profile.
6.4.1 Switching the appliance on and off
Once the user profile has been changed, the display switches to the start screen. Touch VF XXXYY on the display to
switch to the controller view. Press the ON/OFF
symbol on the touch screen unit. The temperature and "collective
alarm" appear on the display. Acknowledge the alarm.
To switch off the appliance, first press the ON/OFF symbol
on the touch screen unit and then set the main switch to
position 0.
Caution:
To switch off the chest freezer for longer periods, press the ON/OFF symbol on the touch screen unit
until OFF appears on the display and then set the main switch to position 0.
If the alarm contact of the alarm system (see point 7 of the operating instructions) is connected to an in-
house fault monitoring system, an alarm is triggered when the cabinet is switched off.
Inform the office responsible for monitoring faults well in advance that you intend to switch off the chest
freezer.
Caution:
If the appliance is only switched off at the main switch, the "power failure" alarm triggers and the appliance
records the temperature inside the cabinet for approx. 35 hours, powered by the internal battery.
