Troubleshooting
Table of anomalies and remedies
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 heat exchanger.
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
