This example shows an upper temperature limit of 55 °C and
a lower temperature limit of 15 °C. The dead-band is set to
10.
If an alert is triggered at 55 °C, the sensor has to measure
45 °C or less, before another alert is triggered on again
exceeding 55 °C.
4.4.2 Temperature alerts
Querx TH supports for types of temperature alerts:
Temperature too high
Temperature too low
Temperature rises too fast
Temperature drops too fast
How Querx TH reacts upon occurring alerts is discussed in
chapter 5 'Data access and configuration of interfaces'.
1.
In the configuration interface, open the page
Sensors
/
Temperature.
2.
Optionally, enter a
Sensor name
, through which it can be
identified in alert notifications.
1.
Set
Upper limit
to the value at which the maximum
temperature is exceeded.
2.
Set
Lower limit
to the value at which the minimum
temperature is under-run.
3.
Set
Alert delay
to the number of seconds, that a threshold
needs to be exceeded, before an alert is triggered.
4.
Set
Dead-band
to an appropriate value, for example 0.5.
1.
Set
Drop value
to the number of units, that the measured
value may drop within a defined period of time.
Configuration
