ture sensor" and "Enabled".

correctly, fault message A3 appears on the display.

ture sensor test, see Maintenance.

gas temperature sensor in the flue gas connection.
Note
The burner remains blocked until the test has been
passed.

ON/OFF switch off and then back on again.
Confirm the commissioning assistant with "Next".
