9.5.2
Continuous purging function, (only for
applications in which this is provided for)
Continuous purging is an operation that maintains the air purging
regardless of whether there is a request for the burner to turn on
or not. From the moment it is set, the motor keeps running wheth-
er the limit thermostat (TL) has not been switched (burner off), or
when the burner is blocked.
Only when the limit thermostat (TL) is switched does the motor
stop for the standby time of four seconds (standby position = t2 +
t1).
The function can be set from the reset button when the limit ther-
mostat (TL) is not switched (burner off), by following the proce-
dure in the post-purging function paragraph 9.5.1 "Post-purging
function (t6) by pressing the button 7 times = continuous purg-
ing.
To reset this function, press and hold the button for at least 5 sec-
onds at least, till the LED indicator changes to red then release it
without carrying out any operation, then wait for 20 seconds for the
burner to start again.
If when the limit thermostat (TL) switches, there is an extraneous
light the motor stops as long as the extraneous light is there fol-
lowed by the block.
The control box's factory settings are as follows: 0 minutes = no
continuous post-purging.
