TROUBLESHOOTING
In case of water leaks or abnormal operation,
disconnect the device from power supply immediately
and close the water taps.
Should you encounter any of the anomalies below,
avoid taking actions on your own and contact
immediately an authorised technical support centre or
qualified staff.
Troubleshooting table
The interventions must be carried out by a qualified
installer or by a specialised support centre.
Effect
The ventilation is delayed with respect to
the new temperature or function settings.
The device does not activate the
ventilation.
The ventilation does not start even if
the water circuit is filled with hot or cold
water.
The device is losing water in heating
mode.
There is dew on the front panel.
There are water drops on the air vent.
The device is losing water in cooling
mode.
The device generates excessive noise.

Cause
The circuit valve requires a certain time
to open and therefore to make the hot
or cold water circulate inside the device.
Cold or hot water is missing from the
system.
The hydraulic valve stays closed
The ventilation motor is jammed or burnt.
The wirings are not correct,
Leaks at the hydraulic connections of the
system.
Leaks at the valves unit.
Detaches thermal insulation.
High humidity conditions (>60%) might
generate condensation, especially at
minimum ventilation speeds.
The condensate tray is clogged.
The condensate discharge pipe does
not have the slope required fro correct
drainage.
The connection pipes and the valves
unit are not well insulated,
The fan touches the structure.
The fan is unbalanced.
Check if the filters are dirty and clean
them if necessary
The ventilation does not start even if the water circuit
is filled with hot or cold water.
The device is losing water in heating mode.
The device is losing water in cooling mode.
The device generates excessive noise.
There is dew on the front panel.
Solution
Wait 2 or 3 minutes to allow the circuit
valve to open.
Make sure the boiler or the water cooler
are on.
Demount the body of the valve and
check if the water circulation is restored.
Check the valve operation feeding it
separately to 230 V. If you were to turn,
the problem may be in the electronic
control.
Check the motor windings and check if
the fan rotates freely.
Check all wirings.
Check the leak and tighten the
connections.
Check the condition of the gaskets.
Check the correct positioning of the
thermal and acoustic insulations paying
particular attention to the front one
located on top of the finned coil.
As soon as the level of relative humidity
drops, the phenomena disappears.
However, a few water drops falling
inside the device will not cause any
malfunction.
Slowly pour a bottle of water in the
lower section of the battery to check the
drainage; if necessary clean the tray and/
or improve the slope of the drain pipe.
Check the pipes insulation.
Check if the filters are dirty and clean
them if necessary
The unbalancing generates excessive
machine vibrations: replace the fan.
Clean the filters
