After turning on the temperature control unit, thermoregulation is always started. An INFO appears
for a few seconds. This makes it possible to suppress the automatic start.

the power outage.

Alarm functions
An alarm is a system state that signals unfavorable process conditions. The temperature control unit
can be programmed so that the plant operator is warned when defined limit values are exceeded.
The response of the temperature control unit to an alarm can be determined. Possible responses
are: Switch off temperature control or control temperature to a safe setpoint (2nd setpoint).
1.5.3.3
Warning messages
Warning messages contain a message about the irregularity of the temperature control unit. These
messages have no further consequences. The plant operator evaluates the relevance of the message
and takes action where necessary.
