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 verication time: time following start-
up of main power supply
t2l
Check for extraneous light or false ame signal dur-
ing t2: the burner controller waits for time t2 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 ame signal
during pre-purging: the burner controller enters
lockout after time t3l
t3i Spark pre-ignition time
ts Safety time
t4i Total spark ignition time
t4l
Valve deactivation reaction time following ame
failure
t5i Spark post-ignition time
- Time needed to reset controller from reset button
- Time needed to reset controller from remote reset
tr
Cycle repetition: max. 3 repeats of the complete ig-
nition sequence if ame fails during normal func-
tioning; the controller enters lockout if no ame 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
