Normal operation with preheating

Yellow
Flame loss during operation (Recycle max 3 attempts)
MV = still
Yellow
Signal not required

t1 Waiting time of a control box input signal: reaction time,
the control box stands still for the time t1.
t1I Presence of extraneous light before the heat request: if
the presence of light during the t1l time, a block follows.
t2 Wait time after a request for heat:
the control box stays still for the t2 time.
t2I Presence of extraneous light during the oil preheating:
if the presence of light lasts the t2l time, a block follows.
t2p Maximum preheating time: if the thermostat K does not
make the switch within the time t2p a block follows, the
control box remains still for the time t2p.
t3 Pre-purging time
start of the fan motor.
t3I Presence of an extraneous light during pre-purging.

total turn on time ts + t5i.
t5i Transformer post- turn on time:
additional turn on time after ts.
t4I Flame loss in operation:
maximum oil valve drop reaction time, after three recycle
attempts a block follows.
t6 Post-purging time:
additional purging time on the opening of the heat limit
thermostat (TL).
t6I Presence of an extraneous light during post-purging. if
the presence of light lasts the t6l time, a block follows.
t7 Long pre-purging time
pre-purging time more than t3.
