Standby time pending an input signal to control box:
t1
reaction time, the control box stands still for the time t1.
Flame or flame simulation detected before demand for
t1I heat: if the presence of light lasts for the t1l time, a block
follows.
Wait time after a request for heat:
t2
the control box remains idle for the t2 time.
Check whether the motor rotation is already present at
the moment of request for heat: the control box remains
t2a
in standby status, then there is a lockout if the number of
rotations is greater than, or equal to, 520rpm.
Flame or flame simulation detected before during
t2I standby time: lockout occurs if flame or flame simula-
tion persists for time t2l.
t3 Pre-purging time: start of the fan motor.
Time for checking the motor rotation during pre-purging:
t3a if the number of rotations is less than 520rpm, after t3a
there will be a lockout
Flame or flame simulation detected during pre-purging
t3I
and pre-ignition: immediate lockout.
t3i Pre-ignition time of the igniter.

A recycle is carried out if the motor rotation drops below
t3r 520rpm during pre-purging and pre-ignition: after 3 recy-
cle attempts, there is a lockout
Safety time:
if, at the end of the time ts there is no flame, the start-up
ts
cycle is repeated. After 3 firing attempts, there is lock-
out.
Post-ignition time of the igniter: the igniter works during
t4i
the safety time.
Time for checking rotation during the safety time ts, or in
t4a normal operation: if the number of rotations drops below
520rpm, the control box goes immediately into lockout.
Flame loss in operation: valve drop maximum reaction
t4I
time, lockout occurs after 3 recycle attempts.
Post-purging time: additional purging time on the open-
t6
ing of the heat limit thermostat (TL).
Flame or flame simulation detected during post-purging:
t6I lockout occurs if flame or flame simulation persists for
time t6l.
