Advanced functions
The ASF alarm goes off automatically as soon as 50 % of the set tolerance band of the set-
point (in the example 50 °C ± 1 °C) is reached again (section A).
If the temperature setpoint is altered, the ASF is automatically disabled temporarily (see in
the example: The setpoint is changed from 50 °C to 25 °C, section D), until it has reached the
tolerance range of the new temperature setpoint (section E).
