DESCRIPTION
VALUE
t0
Standby: the burner waits for a heat request
-
t1
Standby time for an input signal: reaction
time, control box remains in waiting mode
for t1
≤
1 sec
t2
Initialisation verification time: time follow-
ing startup of main power supply
3,5 sec
t2l

Cycle repetition: max. 3 repeats of the com-
plete ignition sequence if flame fails during
normal functioning; the controller enters
