by the dead-band value, before being able to trigger a
further alert.
The minimum temperature is set to
15°C
in the example
depicted above. The dead-band is set to
5°C
.
An alert is triggered if the temperature falls below the
minimum temperature
(1)
. If the temperature falls below
this value again after having returned towards its normal
state by less than the value assigned to the dead-band, no
further alert is triggered
(2)
. A further alert is only triggered if
the value has returned towards its normal state by more
than the value of the dead-band
(3)
and then falls back down
below the minimum value
(4)
.
5.1.2 Alert Delays
A delay can be configured for alerts that are based on limit
value transgressions, if you wish to accept short-term
fluctuations. This can, for instance, be useful to allow for a
tolerated decline in temperature during ventilation.
