NOTE In the case of condensing systems with automatic stokers, the outside sensor input can be used to switch off the heating system. A sensor short-circuit at the outside sensor suppresses a fault message regarding this and switches off the system. The message "Heating system off" appears instead of the fault message in this case.

If a heat generator defect occurs (fault message 30-1 or 31-3) and system frost protection is active at the same time, boiler start-up protection is switched off and thus the heating circuit pumps are started to minimise the danger of system freezing.
