Troubleshooting
In case of water leaks or anomalous functioning immediately cut
off the power supply and close the water taps.
Should one of the following anomalies occur, contact an
authorised service centre or an authorised qualified person, but
do not intervene personally.
- The ventilation does not activate even if there is hot or cold
water in the hydraulic circuit.
-
The appliance leaks water during the heating function.
-
The appliance leaks water only during the cooling function.
-
The appliance makes an excessive noise.
-
There are formations of dew on the front panel.
The interventions must be carried out by a qualified installer or by
a specialised service centre.
Effect
Cause
Remedy
A delayed activation of the ventilation respect
to the new temperature or function settings.
The circuit valve needs some time to open
and as a result the hot or cold water takes
time to circulate in the appliance.
Wait for 2 or 3 minutes to open the circuit
valve.
The appliance does not activate the
ventilation.
No hot or cold water in the system.
Check that the water boiler or cooler are
functioning correctly.
The ventilation does not activate even if there
is hot or cold water in the hydraulic circuit.
The hydraulic valve remains closed.
Dismount the valve body and check if the
water circulation is restored.
Check the working efficiency of the valve
by powering it separately with 230V. If it
activates the problem could be the electronic
control.
The fan motor is blocked or burnt out.
Check the windings of the motor and thefree
rotation of the fan.
The micro-switch that stops the ventilation
when the filter grill is opened does not close
correctly.
Check that by closing the grill the micro-
switch contact is activated.
The electrical connections are not correct.
Check the electrical connections.
The appliance leaks water during the heating
function.
Leaks in the hydraulic connections of the
system.
Check the leak and fully tighten the
connections.
Leaks in the valve unit.
Check the state of the gaskets.
There are formations of dew on the front
panel.
Thermal insulation unstuck.
Check the correct positioning of the thermo-
acoustic insulation paying attention to that in
the front above the finned battery.
There are drops of water on the air outlet grill.
In situations of high humidity (>60%)
condensation could form, especially at the
minimum ventilation speeds.
As soon as the humidity starts falling the
phenomenon disappears. In any case the
presence of a few drops of water in the
appliance does not indicate a malfunction.
The appliance leaks water only during the
cooling function.
The condensation bowl is blocked.
Slowly pour a bottle of water in the low
part of the battery to check the drainage; if
necessary, clean the bowl and/or increase
the inclination of the drainage pipe.
The condensation discharge does not need
an inclination for correct drainage.
The connection pipes and the valve unit are
not insulated well.
Check the insulation of the pipes.
The appliance makes a strange noise.
The fan touches the structure.
Check the clogging of filters and clean them
if necessary
The fan is unbalanced.
The unbalancing causes excessive vibrations
of the machine; replace the fan.
Check the clogging of filters and clean them
if necessary
Clean the filters
