TROUBLESHOOTING
Troubleshooting table
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.
- 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.
The interventions must be carried out by a qualified
installer or by a specialised support centre.
Effect Cause Solution
The ventilation is delayed with respect to
the new temperature or function settings.
The circuit valve requires a certain time
to open and therefore to make the hot
or cold water circulate inside the device.
Wait 2 or 3 minutes to allow the circuit
valve to open.
The device does not activate the
ventilation. Cold or hot water is missing from the
system. Make sure the boiler or the water cooler
are on.
The ventilation does not start even if
the water circuit is filled with hot or cold
water.
The hydraulic valve stays closed
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.
The ventilation motor is jammed or burnt.
Check the motor windings and check if
the fan rotates freely.
The wirings are not correct, Check all wirings.
The device is losing water in heating
mode.
Leaks at the hydraulic connections of the
system. Check the leak and tighten the
connections.
Leaks at the valves unit. Check the condition of the gaskets.
There is dew on the front panel. Detaches thermal insulation.
Check the correct positioning of the
thermal and acoustic insulations paying
particular attention to the front one
located on top of the finned coil.
There are water drops on the air vent.
High humidity conditions (>60%) might
generate condensation, especially at
minimum ventilation speeds.
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.
The device is losing water in cooling
mode.
The condensate tray is clogged.
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.
The condensate discharge pipe does
not have the slope required fro correct
drainage.
The connection pipes and the valves
unit are not well insulated,
Check the pipes insulation.
The device generates excessive noise.
The fan touches the structure.
Check if the filters are dirty and clean
them if necessary
The fan is unbalanced.
The unbalancing generates excessive
machine vibrations: replace the fan.
Check if the filters are dirty and clean
them if necessary
Clean the filters
