9.3 Automatic Error Indication
The automatic error indication (alarm output) shall warn the user and guarantee a secure output in the event of a
system error. In the first place, however, its task is to switch the system off in case of a faulty setup or a defect in the
sensing head or in the electronic circuits.
Never rely exclusively on the automatic error indication when monitoring critical heating processes. It is
strongly recommended to take additional safety measures.
