PoKo (potential free contact) Alarm plug connector
Signal contact for external monitoring
Observe the functional options, which the PoKo provides in the main menu.
The potential free contact (PoKo) signals the condition of the temperature control
device by means of the contact position. A closed operating contact means ready
status (must be set via the menu). The operating contact is open in case of a fault or
error (this applies to the normally open contact between pin 1 and pin 2). Further
applications are possible e.g checking of the actual value. The connection is designed
as a potential free changeover contact.
