DESCRIPTION
t0
Standby: the burner waits for a heat request
t1
Input signal standby time: reaction time, the burn-
er controller waits for time
t1
t2
Initialisation verification time: time following start-
up of main power supply
t2l
Check for extraneous light or false flame signal dur-
ing
t2
: the burner controller waits for time

then
enters lockout; the motor does not start
t2p
Maximum fuel oil pre-heating time: the burner
controller waits for time
t2p
then enters lockout
t3
Pre-purging time: the fan motor runs then the fuel
oil valve opens
t3l
Check for extraneous light or false flame signal
during pre-purging: the burner controller enters
lockout after time t3l
t3i
Spark pre-ignition time

t4l
Valve deactivation reaction time following flame
failure
t5i
Spark post-ignition time

tr
Cycle repetition: max. 3 repeats of the complete ig-
nition sequence if flame fails during normal func-
tioning; the controller enters lockout if no flame is
detected after the last ignition attempt
tpp
Post-purging time: supplementary purge at the
end of the heat request Post-purging can be inter-
rupted by a new heat request
