Checking the high limit safety cut-out (STB)

The high limit safety cut-out interrupts the energy supply
when the maximum permissible flow temperature is
exceeded. To enable the boiler to be reset and re-
started, the fault must be removed and the system must
have dropped below the limit.
Check the high limit safety cut-out function
( control device service instructions).
