List of the phases

Ph00

Lockout phase

Ph01 Safety phase

Ph10 t10 = closure in pause

Ph12 Standby

Ph22 t22 = Uphill train of the fan motor (fan motor = ON,

safety valve = ON)

Ph24 The burner moves to the pre-purging position

Ph30 t1 = pre-purging time

Ph36 The burner moves to the ignition position

Ph38 t3 = pre-ignition time

Ph40 TSA1 = safety time 1 (ignition transformer ON)

Ph42 TSA1 = safety time 1 (ignition transformer OFF), t42 =

pre-ignition time OFF

Ph = Phase

Ph44 t44 = interval time 1

Ph60 Operation

Ph62 t62 = max. time to reach the low flame (the burner

moves to the switch-off position)

Ph70 t13 = post-combustion time

Ph72 The burner moves to the post-purging position

Ph74 t8 = post-purging time

Ph80 t80 = emptying time (valve leak detection)

Ph81 t81 = atmospheric test time (valve leak detection)

Ph82 t82 = filling time (valve leak detection)

Ph83 t83 = pressure test time (valve leak detection)

Ph90 Standby time due to lack of gas
