The probe has a high setting because it is designed to operate as a
probe for switching off the ventilation rather than a probe for
lighting. In fact, it is more convenient that the fans switch off
automatically when you are not near the insert rather than at the
beginning when it is still carrying out the initial lighting.
The temperature probe is located behind the On button; it is easily
accessible and can be checked by disassembling the front panel
(SmartBox) or taking off the fan box (Climasystem) by first removing
the screws that secure it.
To check that the probe works properly, position the button
on II, heat the probe with a hair dryer and wait for the fans
to switch off. In this manner you can check that the probe is
intact.
Never perform this check by subjecting the probe
directly to open flames (cigarette lighter, matches,
etc.) since this could irreparably damage the probe.
If the reaction times of the probe are too long, then you should check
why the structure takes a long time to increase its temperature.
Normally this phenomenon is caused by unsuitable wood or wood with
a low heat yield (see section “4.10 Choice of fuel”) or because the
performance of the chimney flue does not allow suitable discharge of
the fumes and a correct combustion.
5.5. SMARTBOX F80 VN NATURAL VENTILATION
The insert can also operate by natural convection, which means that
the flow of hot air can pass through the entire structure even without
the aid of fans. The Smartbox F80VN maintains as a hot air outlet the
two fins located above the fire door (figure 6) from which a natural air
flow will emerge at high temperatures that will be uniformly dispersed
throughout the room.
5.6. FORCED VENTILATION OPERATION for the CLIMASYSTEM MODELS
The only substantial difference between the ventilation of the
Climasystem and that of the Smartbox is represented by the fact that
the Climasystem model has three fans which are more powerful and
that the button has three positions instead of two.
The operating concept, on the other hand, is the same for the
two models.
• Position I = MANUAL operation
• Position 0 = OFF
• Button on II = AUTOMATIC operation.
5.7. FORCED VENTILATION OPERATION for the SUPERCLIMA MODELS
5.7.1. FC 715 control unit operation
The device allows the speed of the fan, which is controlled by the radio
remote control, to be regulated in one of two modes:
