Temperature alarm threshold
The maximum permitted deviation from the temperature set point in K,
Deviations trigger a tolerance range alarm (chap. 10.5) on the main con-
troller. For technical reasons, the deviation should be at least 1.0K.
0 to 999 min
Temperature alarm-delay time
Period until the main controller triggers a tolerance range alarm after
closing the door. This prevents alarms constantly being triggered during
the unstable operating phase after closing the door.
This has no effect on the safety controller, which can still trigger a limit
alarm or offset alarm.

Setting the offset value for door heating
Offset to the temperature set-point (inner chamber), standard setting 1.5
K. You can use this value to increase (setting 1.0 K) or decrease (setting
2.0 K) inner chamber humidity.
