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: the appliance stands still.
Wait time after a request for heat:
t2
the control box stays still for the t2 time.
Check whether the air pressure switch has already been
moved to the work position before the required heat:
the control box remains in standby status, a lockout fol-
t2a
lows if the air pressure switch remains switched for the
T2a time.
Flame or flame simulation detected before during
standby time:
t2I
lockout occurs if flame or flame simulation persists for
time t2l.
Pre-purging time:
t3
start of the fan motor.
Time for checking the switching of the air pressure
switch in the operating position during the pre-purging
t3a
time: if the pressure switch does not switch within t3a
a lockout follows.
Opening time of air damper opening motor:
time to reach the opening position of the electrical

damper.

Flame or flame simulation detected during pre-purging:
t3I
immediate lockout.
A recycle attempt is made in the event of a pressure
drop during pre-ventilation: in the case of a second air
pressure drop between the 16th and 29th second
t3r
another lockout follows; if there is a pressure drop
between the 30th second and 40th second , the appli-
ance immediately goes into lockout.
Safety time:
if at the end of the ts time there is no flame, a lockout
ts
follows.
Air pressure drop checking time during the ts time and
the normal operation:
t4a
the control box locks out immediately.
Transformer turn on time:
t4i
total ignition time.
Flame loss in operation:

t4I
3 recycle attempts.
Post-purging time:
