These settings can only be made if the relevant input has previously been activated via
“Extra configuration”.
For more detailed information, refer to section 13.5 “Fault properties”.
The text for the fault inputs is predefined as

Signal delay
The fault status message delay is used to set the period of time to elapse for a fault to
be handled as such.
Parameterization “Stop“ at the universal fault inputs means that all function blocks
(boiler, main controller, primary controller, heating circuits, and DHW) will be switched
off by the controller. Frost protection, however, continues to be active.

The digital fault inputs cannot be monitored. We recommend to use wiring where the
signal drops out when there is a fault pending.
13.8.2 Analog fault input with limit value supervision
An analog input can be monitored for limit value crossings.
An input that is already configured can also be monitored. For example, the main flow
temperature sensor can also be monitored to ensure that a maximum flow temperature
will not be exceeded.
