II.c) Firing up
This function allows you to easily fire up the boiler. After igniting the
boiler, you need to activate an automatic fire-up cycle. By selecting optimum
parameters, the boiler uses the zPID function to smoothly switch to the duty
mode. If the boiler reaches the
fire-up threshold
temperature,
the fan
item
will appear instead of the
fire-up
function. From now on, the option will be
used to activate/deactivate the fan. This setting allows you to temporarily
deactivate the fan at any time, e.g. while feeding fuel.
If during the fire-up cycle the boiler does not reach 40
O
C
within 30
minutes,
(default parameters), the following warning message will appear
on the display:
To restore the boiler to operation, switch off
the alarm
by pressing the
encoder
and restarting the
fire-up
procedure.
