Note: Depending on the inertia of your cooling circuit an overshooting of the temperature may be possible.
Example: You want to have an alarm monitoring for the cooling chamber mentioned above. The
alarms should start when the temperature will be rising above
–15°C or falling
below
–30°C. Therefore you have to select –15°C for the maximum alarm-value “Al.Hi“
and
–30°C for the minimum alarm-value “AL.Lo“.
The alarm will be starting after the temperature rises above
–15°C and stays above –
15°C for the entered delay time or after it had been falling below
–30°C and stays below
–30°C for the entered delay time.
Please note that the alarm-outputs are inverted! This means, that the output will be active when
there is no alarm.

as often till the device executes a reset. The values will be stored at it.
Example: You want to have a temperature alarm-monitoring of a greenhouse. The alarm should
start when the temperature rises above 50°C or falls below 15°C.
Therefore your settings will be 50°C for the maximum alarm-
value “AL.HI“ and 15°C for
the minimum alarm-
value “AL.Lo“. The alarm will be starting after the temperature rises
above 50°C and stays above 50°C for the entered delay time or after it had been falling
below 15°C and stays below 15°C for the entered delay time..
