Return to Normal display:
If no entry is made for 120 seconds, the controller returns from each menu to normal display.
To directly return from each menu to normal display, keep pressed down the confirmation button and
press the arrow-up button, if appropriate, several times. Each time you press the arrow-up button the
controller goes back one level.
5.1 Menu structure overview
Normal display

If there is no indication on the controller, press the confirmation button until the display lights up.
The controller now shows normal display (chap. 5).
Warming chambers may release odors in the first few days after commissioning. This is not a
quality defect. To reduce odors quickly we recommend heating up the chamber to its nominal
temperature for one day and in a well-ventilated location.
6.1 Adjusting air change
Opening the black exhaust air flap on top of the chamber serves to adjust the air change.
BD-S / BD-S-UL, ED-S / ED-S-UL: The open exhaust air flap allows increasing fresh air circulation through
the exhaust air outlet.
FD-S / FD-S-UL: The open exhaust air flap and fan operation allow fresh air to come in through the venti-
lation gaps.
Note: If the exhaust air flap is completely open, the spatial temperature accuracy can be negatively influ-
enced.
For connection to an exhaust/ventilation system see chap. 4.2.
