Signal delay
The fault status signal delay is used to set the period of time a fault must be pending to
be handled as such.
When parameterized “Stop“ at the universal fault inputs, the controller switches off all
function blocks (boiler sequence manager, all boilers, primary controller, and the heat-
ing circuit). Frost protection continues to be active.
