Monitoring of Heatup and Cooling
The undertemperature alarm values are not a factor of the setpoint during the
heatup phases of the individual temperature channels. They are based on a
theoretical actual value. This causes an alarm to be triggered when the
heatup phase is longer than anticipated.
The same applies to the overtemperature alarm values during the cooling
phases.
