Troubleshooting
In the event of water leaks or anomalous operation,
disconnect mains power immediately and close all
water taps.
If one of the
occur, contact an
or qualified personnel, do not try to repair yourself.
Troubleshooting table
Maintenance must be carried out by a qualified installer or
by a specialised service centre.
Effect
Ventilation takes a long time to start
when new temperature settings or
anew mode is activated.
The device doesn't start ventilating.
Ventilation does not start even if there
is hot or cold water in the hydraulic
circuit.
The device leaks water when heating.
Rust is forming on the front panel.
Water droplets are forming on the grill
and the air outlet.
The device leaks water only when
cooling.
The device makes excessive noise.

authorised service
Cause
The circuit valve needs time to open
and to let cold or hot water circulate.
No hot or cold water in the system.
The hydraulic valve stays closed.
The fan motor is blocked or burned
out.
The microswitch that stops ventilation
when opening the filter grill doesn't
close properly.
Electrical connections are incorrect.
Water leakage from the system
plumbing.
Leaks from the valve group.
Thermal isolators detached.
In high relative ambient humidity
(>60%), condensation
especially when the fan is at its
minimum speed.
The condensation tank is blocked.
The condensation drain does not have
sufficient incline to drain.
The connection pipes and valve group
are not well isolated.
The fan is touching the structure.
The fan is unbalanced.
Check for dirt in filters and if necessary,
clean them.

may occur,
Solution
Wait 2 or 3 minutes for the circuit valve
to open.
Check that the boiler or the water
cooler are working.
Disassemble the valve body and check
and restore water circulation.
Check that the valve is working by
powering it up separately from a 230V
supply. If it starts working, the problem
may be with the electronic controller.
Check the motor windings and that the
fan can turn freely.
Check that closing the grill closes the
contact on the microswitch.
Check the electrical connections.
Check for leaks and tighten all
connections.
Check the seals.
Check that the thermal
isolators are positioned correctly,
paying particular attention to the one
positioned at the front above the
winged battery.
As soon as relative humidity decreases,
the problem will disappear. In any
case, should some water droplets fall
inside the units, it does not mean that
there is a malfunction.
Slowly pour a bottle of water in the
lower part of the battery to check
drainage; if required, clean the tank
and/or improve the incline of the drain
tube.
Check pipe insulation.
Check for dirt in filters and if necessary,
clean them.
An unbalanced fan causes excessive
vibrations in the machine: replace the
fan.
Clean the filters.
