Safety functions
Level sensor
If the water level in the boiler decreases, the level sensor temporarily turns off the boiler
and triggers a warning.
If the level sensor has turned off the boiler, do not start the boiler again,
rather contact your installation engineer for troubleshooting and remedial
actions.
Over-temperature protection
The over-temperature protection is a digital safety feature. The boiler activates the
over-temperature protection before the mechanical overheating protection is triggered.
If the over-temperature protection is activated, you can reset the warning
yourself. Read about how to reset warnings on page 17. If the over-
temperature protection is triggered repeatedly, you must contact your
installation engineer for troubleshooting and remedial actions.
Overheating protection
The overheating protection is a mechanical safety feature that is triggered if the boiler temperature
exceeds 80°C.
If the overheating protection is triggered, you will need to reset it manually.
If the overheating protection is triggered repeatedly, contact your
installation engineer for troubleshooting and remedial actions.
