Fault during commissioning (fault message 416)
During commissioning, the control unit checks for cor-
rect placement of the flue gas temperature sensor. If
fault message 416 is displayed:
1.
Check whether the flue gas temperature sensor is
correctly installed (bayonet fitting). See previous
diagram.
2.
If required, correct the position of the flue gas tem-
perature sensor.
3.
Check the flue gas temperature sensor resistance.
See previous chapter. Replace faulty flue gas tem-
perature sensor if required.
4.
Turn off the ON/OFF switch.
5.
Turn the ON/OFF switch back on.
Restart the commissioning assistant.
6.
Check for leaks on the flue gas side.
Note
If fault message 416 continues to be displayed
although the flue gas temperature sensor is correctly
positioned: Initial commissioning may result in burner
faults e.g. caused by air in the gas line. Eliminate the
fault and reset the appliance.
Information on replacing the HBMU heat management unit
If replacing the HBMU heat management unit, the
"Vitoguide app" must be used.
See spare part installation instructions and inter-
