Attention!
The factory setting for door alarm activation is 5 minutes. To change this setting, contact
the distributor/seller of the appliance. The user can only enable/disable this function.
- High temp. alarm - If the temperature in the appliance rises above the “High
temp” setpoint longer than the “Alarm delay” setting defines, the high
temperature alarm will be activated.
If products with a temperature above the “High temp” setting is placed in the
appliance near the temperature probe, it may trigger the high temperature
alarm.
Example:
The setpoint is -80°C, the “High Temp.” is set to -70°C and the ”Alarm delay”
is 15 minutes. When the temperature in the appliance rises above -70°C for 15
minutes or longer, the alarm will be activated.
Please note: The temperature probe is measuring the temperature of the air
in the appliance, not the temperature of the products placed in the appliance.
The temperature of the air will change more rapidly than the temperature of
the products.

Attention!
When changing the high temperature setting, remember to have the setpoint of the
appliance in mind. If the “high temp.” is set lower than the appliance setpoint, this will
activate the alarm. You can change the time settings for the “high temp” in the custom
menu when accessing “temp. Alarm delay”.
- Low temp. alarm - If the temperature in the appliance falls below the “Low
temp. alarm” limit for a period longer than the “Alarm delay”, the low
temperature alarm is activated.
If products with a lower temperature than the low temperature alarm setting is
placed against or close to the temperature probe inside the appliance, it may
result in the low temperature alarm being triggered.
Example:
The setpoint is -80°C, the “Low Temp.” is set to -95°C and the ”Alarm delay”
is 15 minutes When the temperature in the appliance falls below -95°C for 15
minutes or longer, the alarm will be activated.
Please note: The temperature probe is measuring the temperature of the
air in the appliance, not the temperature of the products placed in the
appliance. The temperature of the air will change more rapidly than the
temperature of the products.
Attention!
When changing the low temperature setting, remember to have the setpoint of the
appliance in mind. If the “low temp.” is set higher than the appliance setpoint, this will
activate the alarm. You can change the time settings for the “low temp” in the custom
menu when accessing “temp. Alarm delay”.
- Case 1: A door opening can cause the temperature to rise inside the cham-
ber. In this case, the temperature rises above the High Temperature alarm
level, but falls again within 15 minutes. In this case, no alarm is
activated.
- Case 2: Loading products in the chamber can cause the temperature to
rise inside the chamber. In this case, the temperature rises above the High
Temperature Alarm Level, and the recovery time last longer than 15 minutes.
– Therefore, the High temperature alarm will be activated.
