Example:
min. 10°C / max. 18°C / Hysteresis 2°C
When a limit is exceeded the alarm status is reset when 16°C (18-
2) is reached or when the value falls below 12°C (10+2). If the
temperature rises or falls by more than 2°C in five minutes the
alarm is also triggered.
Relative Humidity/Scalar / Absolute Humidity:
The settings made here have exactly the same function as the
temperature settings.
Delay Time: The alarm is triggered with a delay of this time (in
minutes) to compensate for short-term limit value violations.
Interval: Enter here the send interval (in minutes) for sending a
message when there is an active alarm. If you want to send just a
single message, enter an „E“ here.
Timer: This timer interval is based on the CRON service such
as is used in Linux/Unix systems. Valid characters are:
* : stands for all valid values in the respective input field (e.g.
all minutes or all hours)
- : specifies a range of from ... to .. For example, weekday „2-4“
stands for Tuesday to Thursday, whereas entering a „*“ triggers
the timer on all weekdays.
/ : Interval within the entered range , e.g. minute „0-45/2“ starts
the timer in the range between the 0th and 45th minute every
two minutes (0, 2, 4, 6 ,8, 10, ... , 44).
, : specifies an absolute value. For example minute 0, 15, 30
starts the timer on the hour, quarter-hour and half=hour.
This function requires that the „Timer“ box be checked.
