5 - INCONVENIENCES AND POSSIBLE SOLUTIONS
MALFUNCTION
Ventilation activation is delayed with
respect to the new temperature or
function settings.
Ventilation speed increases or de-
creases automatically.
The appliance does not start ven-
tilation.
The fan does not activate even
if there is hot or cold water in the
hydraulic circuit.
The appliance loses water during
heating function.
Dew formations are present on the
front panel.
A few water drops are present on the
air outlet flap.
CAUSE
- The circuit valve requires a
certain time for its opening and
therefore to make hot or cold
water circulate in the appliance.
- The electronic control works so
as to adjust the best level of
comfort.
- Hot or cold water is missing in the
system.
- The hydraulic valve remains
closed
- The ventilation motor is locked or
burned out.
- The electrical connections are not
correct.
- Losses in the water connection
of the system.
- Losses in the valves unit.
- The thermostatic valve integrated
in the connection unit between
panel and battery does not close
flow towards the wall.
- Thermal insulators are discon-
nected.
- In situations of high relative am-
bient humidity (>60%) conden-
sation phenomenons may occur,
especially at minimum ventilation
speeds.
SOLUTION
- Wait 2 or 3 minutes so that the
circuit valve opens.
- Wait for temperature adjustment
or select silent function in case
of need.
- Check that the boiler or the water
refrigerator are operational.
- Dismount the valve body and
check if water circulation is
restored.
- Check the operating status of the
valve by powering it separately at
220 V. If it activates, the problem
may be in the electronic control.
- Check the motor windings and
the free rotation of the fan.
- Check the electrical connections.
- Check the loss and firmly tighten
the connections.
- Check the status of the seals.
- Replace the junction which
integrates the thermostatic valve
in the water inlet upper unit.
- Check for correct positioning of
the thermoacoustic insulators,
paying particular attention to
the front one above the finned
battery.
- Once relative humidity drops, the
phenomenon disappears. In any
case, the possible fall of some
water drops inside the appliance
does not indicate a malfunction.
