• Domestic water sensor
If there is no sensor or if a short circuit occurs, an error warning
(50) is triggered and all the functions associated with it are
automatically deactivated.
• Flue gas sensor
These sensors must always be present. They are being constantly
monitored. If there is a sign of irregularity, the boiler will
automatically switch off.
• Boiler’s frost protection functions
Once the boiler temperature falls below 5°C, the function for the
protection of the boiler from frost turns on the boiler. The boiler
will then heat up instantly to a temperature of 20°C.
• System’s frost protection
The system’s frost protection ensures the protection of the system
in the case of low outdoor temperatures by activating the pumps.
This causes the water in the heating system to circulate.
Depending on the current outdoor temperature, the pumps may
be activated at intervals or permanently. The frost protection
function can be deactivated. (See Parameter
33).
• Boiler behaviour in event of malfunction
The boiler operation will be shut off in the event of dangerous
malfunctions with subsequent fan and pump overruns. Each error
has its own error code (See Chap 6.1.1 Error Codes).
• Emergency functions
If the safety remains intact, the emergency functions will be on; in
other words, the functions that are not affected by the errors will
remain active.
