If one of the parameterized input temperatures is unavailable to the controller for a period longer
than the monitoring time, the controller enters the error mode. The error mode is sent to the bus
as the value 1.
Note
About item 2:
This object must be connected to the "Fault, actual temperature (slave)" object in
order to indicate the error mode.
About item 3:
This object must be connected to the "Fault, actual temperature (slave)" object in
order to indicate the error mode.
