Shut-down test

If the reset push-button is pressed during running operations for
more than 5 seconds and less of 10 seconds the burner will per-
form a shutdown, the oil valve is closed, the flame stop and start-
up sequence restarts.
If the switch off test is enabled, the number of repetitions of the
start up sequence (see paragraph "Recycle and limit of repeti-
tions" on page 28) and the number of possible resets (see par-
agraph "Protection reset" on page 29), are reset.
6.7.4

Intermittent operation

After 24 hours of continuous operation, the control box starts the
automatic switch-off sequence, followed by a restart, in order to
check for a possible fault with the flame sensor. This automatic
switch-off can be fixed at 1 hour, (see paragraph "Programming
menu" on page 32).
The modification of the parameter setting for intermittent opera-
tion takes effect if:
 during the heat request, the switching off test function is ena-

bled;
 there is a flame loss;

 the heat request switches off and then later restarts;

 the control box switches off and restarts;

 the automatic restarting of the intermittent function occurs

(1hour/24hours).

Recycle and limit of repetitions

The control box allows a recycle function, i.e. complete repetition
of the start-up sequence, making up to 3 attempts, in the event
the flame failure during operation.
If the flame failure 4 times during operations, this will cause a
burner lockout.
If there is a new heat request during the recycle, the 3 attempts
are reset when the limit thermostat (TL) switches.
NOTE:
After 510 seconds of continuous operation, a new attempt of
possibility is added.
By disconnecting the power supply, when a new heat request oc-
curs (power supply is applied to the burner) all possible attempts
at re-ignition are reset (maximum 3).
