The control unit can be reset immediately after a lockout has occurred. After resetting (as
well as after correction of a fault, which resulted in a controlled shutdown, or after each
mains failure) the sequence switch always returns to its start position, whereby only
terminals 7, 9, 10 and 11 receive voltage in accordance with the control program. It is only
then that the control unit begins with a new burner start-up.
Do not keep the reset button pressed for more than 10 seconds.
