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.
