TROUBLESHOOTING
TROUBLESHOOTING
6.1 Preliminary warnings
Should you encounter any of the anomalies below:
• 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 loosing water in cooling mode
• the device generates excessive noise
• there is dew on the front panel
Follow the instructions below:
– disconnect the device from power supply immediately
– close the water taps
– contact immediately an authorized technical support
center or qualified staff
The interventions must be carried out by a qualified in-
staller or by a specialized support center.
Do not intervene personally.
6.2 Troubleshooting table
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 on, 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 the electrical connections.
The device is losing water in heating mode.
Leaks at the hydraulic connections of the system. Check the leak and tighten the connection.
Losses in the valve group. Check the condition of the gaskets.
There is dew on the front panel. Detached 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 loosing 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 for
correct drainage.
The connection pipes and the valves unit are not well insulated.
Check the pipe insulation.
The device generates excessive noise.
The fan touches the structure. Verify
The fan is unbalanced.
The unbalancing generates excessive machine vibrations: replace the
fan.
Check the filters for dirt and clean them if necessary Clean filters
